1. Introduction
General Descripon
This manual is intended to provide basic instrucon to qualified personnel on the prop‐
er installaon, operaon, and maintenance of hospital Isolated Power Systems (IPS) as
manufactured by PG LifeLink.
Isolated Power Systems protect paents and aending medical personnel from the
electric shock hazards of common ground faults, without disconnecng power to cri‐
cal electro‐medical equipment. They are intended for installaon inside any Category 1
Space of a Health Care Facility that may be subject to wet procedures, including all
Operang Rooms and many other Crical Paent Care Areas.
In the event that a piece of line‐powered equipment fed from the IPS experiences a
first fault to ground, an integral hospital isolaon transformer safely limits the other‐
wise hazardous fault current to a comparably low level. Unlike other ground fault
protecon methods such as GFCI, which interrupt the circuit aer an actual fault cur‐
rent is detected, a properly installed and maintained IPS impedes the flow of high level
fault currents by eliminang the return circuit path from ground back to the voltage
source. This key feature is the reason that Isolated Power Systems are the preferred
protecon method for all branch circuits serving crical paent related equipment
where loss of power cannot be tolerated.
The Line Isolaon Monitor (LIM) is another standard component of Isolated Power
Systems. It connuously monitors the line‐to‐ground impedance of all isolated branch
circuits including any connected device loads, and acvates an alarm to nofy medical
staffwhenever the system’s Total Hazard Current (THC) exceeds a predetermined val‐
ue. Acvaon of this alarm indicates that a fault path has likely developed somewhere
in the system between one of the two energized conductors and ground. However,
because both lines are isolated from ground, the IPS will connue to provide protec‐
on, allowing staffto safely complete crical procedures. Upon compleon of the case
and safe removal of the paent from the area qualified personnel can idenfy the
source of the high hazard current and correct it as necessary before the next case.

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
Model Types
This manual covers basic installaon and operaon of the following models manufac‐
tured by PG LifeLink:
 IPP-P Isolated Power Panel
Standard IPS with single isolated output
 IPX-P Duplex Isolated Power Panel
Two single voltage IPS panels installed side by side in a single enclosure
 IPL-P Laser Isolated Power Panel
Specialty IPS with single high‐voltage (208 or 240 VAC) output and programmable
control of individual circuits for supplying medical laser devices in up to 12 rooms
 IPD-P Dual Output Isolated Power Panel
Specialty IPS with dual outputs (120 and 208 or 240 VAC) for supplying a medical
laser in addion to typical line powered equipment in a single room
System Components
Each IPS includes the following standard components. Consult PG LifeLink’s website or
equipment catalog for detailed model informaon or product selecon guides. Fea‐
tures such as enclosure size, electrical rangs, number of circuits, and available acces‐
sories vary by model type and are oen unique to customer’s project requirements. In
addion to this document, always review the PG LifeLink shop drawings submied with
each Sales Order for specific panel informaon.
 Backbox
Backboxes are fabricated of galvanized steel and are designed and tested as NEMA
Type 1, general‐purpose enclosures in accordance with UL 50. Flush‐mounted type
is standard, but surface‐mounted opon is available. Contractor may request that
backboxes be shipped for rough‐in phase ahead of remaining items. Note, addion‐
al shipping charges may apply.
 Interior Equipment Chassis
The factory assembled interior chassis module includes all circuit breakers, equip‐
ment ground bus, Line Isolaon Monitor, and associated accessories such as Fault
Locaon or Load Monitoring. For IPP‐P and IPX‐P type panels, the isolaon trans‐
former is also pre‐assembled to the interior chassis, which mounts to four threaded
studs on inside of backbox with provided hardware.
 Line Isolaon Monitor
A Line Isolaon Monitor (LIM) is supplied with each IPS to monitor the Total Hazard
Current (THC) of the system and signal an alarm if this value exceeds 5 mA. Each
LIM includes a wiring harness and terminal block for field connecon of oponal
remote annunciators and other accessories. IPX‐P and IPD‐P type panels each in‐
clude two separate LIMs. An addional manual specific to the model of LIM in‐
stalled will be included with the shipment. Be sure to read the appropriate LIM
manual carefully prior to energizing the IPS panel. Pay close aenon to the voltage
limitaons for the specific LIM being installed. While the standard SafeDetec LIM
will automacally adjust to either 120V or 208V inputs, the older Mark V LIM re‐
quires manual configuraon of the operang voltage via a selector switch/jumper
seng on the circuit board. Connecng a LIM that is manually configured for 120V
operaon to a 208V IPS circuit will cause severe damage to the LIM. Note that
dual‐voltage IPD‐P panels include both 120V and 208V circuits.

 Circuit Breakers
Each IPS includes a primary main circuit breaker which provides overcurrent protec‐
on for the enre system. Per UL 1047, the primary main breaker is sized at 125%
of rated full load amps of the isolaon transformer primary winding. The secondary
winding is connected directly to the lugs of the branch circuit panelboard which
includes up to sixteen 2‐pole bolt‐on branch circuit breakers. Branch breakers are
factory installed according panel schedule(s) or other project documents provided.
Type IPD‐P panels also include secondary main circuit breakers to protect each of
the dual secondary windings independently. The installaon contractor is responsi‐
ble for supplying a suitable upstream feeder breaker to protect the conductors sup‐
pling the primary of the IPS. It is highly recommended that upstream feeder break‐
ers include electronic or adjustable instantaneous trip capabilies that are compa‐
ble with the inducve load inrush current generated by the isolaon transformer.
For more informaon on inrush current, refer to secon 5 or consult our website for
PG LifeLink’s Isolated Power System Design & Installaon Guidelines.
 Isolaon Transformer
Most panels are shipped from the factory with the transformer mounted and pre‐
wired to the interior chassis. On some models, the transformer is shipped on a sep‐
arate skid and must be installed in the top of the enclosure by the contractor. When
shipped separately, ensure that the correct transformer is matched with the panel
interior, and refer to manufacturer’s shop drawings for proper wiring. Larger 15 and
25 kVA transformers can weight up to 350 lbs and may require special liing equip‐
ment for installaon.
 Front Trim
The Front Trim Panel is fabricated from type 304 brushed stainless steel. It mounts
to the backbox via three compound slide hinges and is secured with 1/4‐20 stainless
steel hardware provided. The fully concealed slide hinges allow for easy access to
internal components for maintenance and tesng. The front trim also includes a
lockable hinged door for access to circuit breakers and oponal fault locator/load
monitor interface. The LIM(s) is flush mounted to the trim plate by the installer and
is accessible from the front of the panel when in use.
2. Receiving, Handling, and Storage
Customer should inspect all crates and packages immediately upon receipt. Document
any apparent damage or missing items, and nofy PG LifeLink and/or carrier as soon as
possible to iniate a claim if necessary. PG LifeLink Isolated Power Systems are typically
packaged as three separate components: back box, pre‐wired equipment chassis with
transformer(s), and front trim. Note that the transformers for some larger capacity
systems (such as IPD‐P and IPL‐P) may be packaged or delivered separately.
Equipment chassis plates are supplied by the factory packaged in cardboard containers
and may be stacked 2‐3 per skid, along with associated front trim panels. Pay careful
aenon when moving or unpacking skids, as the front trim panels may be located in
a shallow wooden crate beneath the cardboard containers. Labeling included in the
back boxes, front trim panels, and interior chassis assemblies includes the associated
part number of the matching components. Consult labels in each component to
match the chassis to the correct backbox and front trim. PGL recommends that chas‐
sis assemblies, trim panels, and other parts be stored in a clean, dry, indoor locaon.
Protect equipment from exposure to dust, liquids, paint, and other construcon mate‐
rials before, during, and aer installaon.

5. Installation Instructions
General Installaon Guidelines
A major goal when designing and installing Isolated Power Systems is to minimize
the cumulave leakage current of the installed system. Carefully reviewing and
following these guidelines will help ensure that the installaon passes all required
startup and commissioning test criteria, and safely operates as intended.
 Chapter 6 of NFPA 99 ‐Health Care Facility Code defines the performance
maintenance and tesng requirements for electrical systems in health care facil‐
ies including hospitals and ambulatory surgery centers. Among these is the
requirement that the insulaon impedance of all newly installed IPS be tested
prior to being placed into service. The minimum allowable insulaon imped‐
ance from each energized line to ground, including all branch circuit wiring and
receptacles, is 200,000 ohms. For a 120V system this equates to a maximum of
0.6mA of leakage current. Liming the baseline leakage of the installed system
ensures that adequate operaonal headroom of at least 4.4mA is available for
powering a suitable number of devices without exceeding the 5.0mA Total Haz‐
ard Current alarm threshold.
 Verificaon of baseline system leakage is included with startup/commissioning
tesng service and is performed by a factory technician for all new installaons.
Contact PG LifeLink Field Service at 800-287-4123 to schedule tesng; ad‐
vanced noce is required. Note that acvaon of standard factory warranty is
conngent on compleon of startup tesng by a factory authorized technician.
 In the United States, installers should thoroughly review and be familiar with
NFPA 70 ‐Naonal Electric Code, Arcle 517 (Health Care Facilies) before
aempng to install or wire an Isolated Power System. There are several instal‐
laon requirements specific to health care occupancies that must be followed.
Pay special aenon to Parts I, II, and VII. The following secons specifically
address installaon requirements related to Isolated Power Systems:
 517.13 Grounding of Receptacles and Fixed Electrical Equipment
 517.14 Panelboard Bonding
 517.19 Crical Care Areas
 517.20 Wet Procedure Locaons
 517.160 Isolated Power Systems
Cauon! Hazard of Equipment Damage
 Proper operaon of this equipment is dependent on correct
installaon and setup.
 Do not modify this equipment or use in a manner for which it is
not intended.
 Use only with PG LifeLink recommended accessories.
 Failure to adhere to the instrucons contained in this document
can result in personal injury, equipment malfuncon, or serious
damage to connected equipment.

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
 Canadian installers should review and be familiar with the specific installaon re‐
quirements for Isolated Power Systems found in CSA C22.1 ‐Canadian Electrical
Code, Part 1, Secon 24 (Paent care areas).
 Isolated Power Systems should be located as close as possible to the point of use to
reduce leakage current associated with the branch conductors. Generally, panels
are installed inside the room being served, or just outside in an adjacent corridor
wall. An IPS is only permied to serve one operang room (with the excepon of
high voltage x‐ray/laser panels). When installed outside of the room, a remote an‐
nunciator is required inside of the room to nofy staffof an alarm from the LIM.
 The Paent Care Vicinity is the primary focus for personnel fault protecon. This
area centers on the normal locaon of the surgical table/paent bed, extending 6
feet horizontally beyond the paent perimeter and vercally from the floor up to
the ceiling. Line powered, portable or ceiling mounted equipment which may ex‐
tend into this area such as service booms, pendants, monitors, C‐arms, and surgical
lights should be fed from an un‐grounded isolated power system for protecon
against line‐to‐ground faults without power interrupon. Fixtures and equipment
which do not extend down below the ceiling including overhead lighng should not
be connected to IPS. Non‐medical equipment such as personal computers, moni‐
tors, communicaon, and A/V equipment that is not intended to enter the paent
care vicinity should be fed from normal grounded power circuits with GFCI protec‐
on instead of IPS.
 Note, as with most inducve loads, the inrush current of the IPS isolaon transform‐
er may be up to 15X its rated primary current and may take up to a second to sub‐
side, based on site condions. PGL highly recommends upstream feeder breakers
supplying any IPS panel include electronic or adjustable instantaneous trip capabili‐
es that are compable with the inducve load inrush current generated by the
isolaon transformer. Consult our website for a copy of PG LifeLink’s Isolated Power
System Design & Installaon Guidelines for more informaon.
 Avoid connecng devices with commercial‐grade power supplies including low pass
filter networks or surge protecon circuits (TVSS or MOV line to ground) on IPS.
These devices include capacive coupled current paths from line to ground and can
raise the system Total Hazard Current. If in doubt, verify with device manufacturer if
equipment is compable with medical isolated power systems. In general, only
“Medical Grade” equipment should be connected.
 Do not supply general lighng loads from IPS branch circuits. Permanently wired
overhead ceiling fixtures are considered outside of the Paent Care Vicinity and do
not pose a fault risk to the paent. Typical circuitry contained in these fixtures will
contribute a disproporonately high level of leakage current to the system, leading
to a reduced operang range. However, certain adjustable boom‐mounted lighng
devices such as surgical and exam lights as well as wall mounted x‐ray film view box‐
es are accessible to paents and staffand therefore do require IPS protecon.
 Certain devices are not compable with IPS and therefore should not be installed on
IPS branch circuits. These include:
 GFCI, AFCI, Surge Protected, and Isolated Ground type receptacles, as
well as some receptacles with integral USB charging capability

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual

 Certain Medical‐Grade power strips with loss‐of‐neutral or loss‐of‐
ground sensing circuits
 For addional informaon regarding system compability, contact PG LifeLink’s
engineering team at [phone] or [e-mail]
 Upon compleng installaon, installer should perform the Contractor Isolated Power
System Start‐Up Procedure. A copy of this procedure is included with each panel and
may also be downloaded from our website at hp://www.pglifelink.com/technical‐
resources.
Back Box Installaon
 Installaon of PG LifeLink Isolated
Power Panels is the responsibility
of the installaon contractor
including selecon and supply of
a suitable support structure and
aachment hardware. The size
and maximum weight for each
panel type is listed in Table 1.
 PGL recommends securing panels
to a rigid support structure such
as channel‐strut using minimum
5/16” commercial grade hard‐
ware. Four mounng holes are
located on each side of the back
box for this purpose. If necessary,
use shims between the back box
and support anchorage to ensure
that the sides of the enclosure
are not distorted as the mounng
bolts are ghtened, which may
result in mis‐alignment of the
front trim mounng hardware.
NOTE: Do not locate any mounng hardware or conduit entry points on the rear sur‐
face of the back box. This will interfere with installaon of the interior equipment
chassis as well as the front trim panel.
 When installing flush‐mount type panels, posion the boom edge of the back box
approximately 18 inches above the surface of the finished floor, and ensure that the
front edge is recessed approximately 1/8” behind the final finished wall surface. If
the backbox protrudes beyond the wall, or is recessed too far behind the surface,
this may cause difficulty when securing and aligning the front trim. Keep in mind
that final finished wall and floor dimensions may change significantly aer rough‐in
depending on the types and thicknesses of finishes applied.
 For panels weighing 500 pounds or more, PG LifeLink recommends installing a lower
horizontal brace or saddle to support the underside of the backbox in addion to the
vercal side supports.

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
 A label is affixed inside the back‐
box indicang the correct orienta‐
on. Be sure to install with the
top side facing up so that the
interior chassis will align properly
when installed. A raised chassis
support ledge is located along the
boom interior of the backbox.
 Different models of backboxes
look similar. Verify that the part
numbers marked on the backbox
ID label matches the labels on the
associated equipment chassis and
front trim (shipped separately).
 Install conduit prior to installing
equipment chassis assembly.
Remove all metal shavings and
clean interior to avoid contamina‐
on of equipment.
 All conduit should enter from the
top of the enclosure to allow
proper clearance for installaon
of the equipment chassis assem‐
bly. Installer may locate and in‐
stall branch circuit conduits as
convenient along the top surface
of the back box, being careful to
maintain adequate separaon
between isolated branch circuit
conductors and non‐isolated feed‐
er conductors, as well as low‐
voltage signal wires connected to
the remote terminal block. Loca‐
on of primary main and remote
terminal connecon points vary
by model. Always refer to specific
project drawings when locang
conduit entry points.
 If site condions require locang
conduit on the sides or boom of
the enclosure, it is recommended
that installer first pre‐install the
equipment chassis (and trans‐
former if shipped separate from
the chassis) prior to drilling to ensure proper clearance can be maintained.
 Conduit runs for branch circuits should be as short and direct as possible to minimize
accumulated leakage current. Generally, the maximum recommended cumulave

length of for all branch circuit conductor pairs from a single transformer is 500 feet.
Avoid unnecessary bends and juncons where possible.
 In accordance with NEC 517.13 (A), all branch circuit conduit shall be metallic and
“shall itself qualify as and equipment grounding conductor in accordance with [NEC]
250.118”. In Canada, branch circuit conduit must be non‐metallic in accordance with
CEC Part 1 Secon 24‐204(2)(f).
Interior Equipment Chassis Installaon
 The equipment chassis has four
mounng slots which align with four
threaded studs on the inside rear of the
backbox. A mounng ledge is also pro‐
vided along the boom of the backbox
which supports the weight of the chas‐
sis and aligns it vercally with the front
trim.
 When removing the chassis from its
packaging , transporng or liing it into
place inside the enclosure do not place
pressure on or use any of the compo‐
nents or brackets for liing. Use only
the sides of the main chassis plate for
liing. If the chassis assembly includes
an oponal power receptacle or ground
jack accessory plate it may be temporar‐
ily removed to facilitate chassis installa‐
on. Note that the equipment chassis is extremely heavy and can weigh up to several
hundred pounds. Do not aempt to lior install chassis assembly or transformer
without proper safety equipment. The two mounng slots at the top of the chassis
may be used as liing points.
 To install the chassis, first rest its boom edge on the mounng ledge and align the
lower open ended slots with the studs in the rear of the backbox, then lt up and into
place, engaging the upper mounng slots with the studs. Secure with four 5/16‐18
nuts and washers provided, ensuring that chassis is flush against the rear of backbox.
 A serialized idenficaon label is affixed to each equipment chassis as well as the
circuit breaker dead‐front barrier. Ensure that the serial numbers are the same on
both labels and do not switch barriers with another panel.
 The Line Isolaon Monitor and wiring harness is included with the equipment chassis
and is packaged independently in cardboard to protect it during shipping and storage.
The LIM will be installed directly to the rear of the Front Trim in a subsequent step
(see Front Trim Secon). Do not remove the LIM from its packaging unl final assem‐
bly stage. Ensure that LIM is installed only with the equipment chassis with which it
was originally packaged. Note that connecng some older LIMs (such as the Mark V)
to a panel with the wrong voltage will cause severe damage to the device and will
void the warranty.

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
Isolaon Transformer Installaon
 While most chassis assemblies include a
pre‐wired, low‐profile isolaon trans‐
former mounted directly to the chassis
assembly, certain model types, including
IPD‐P and IPL‐P panels require installa‐
on of a separate, shelf‐mounted trans‐
former in the upper poron of the back‐
box. These components are typically
very heavy and require suitable liing
equipment. Use only the liing points
on either side of the top support rail
when liing or transporng transform‐
ers. Do not exert pressure on the wind‐
ings or wire leads while liing or manip‐
ulang.
 To install upright, shelf‐mounted trans‐
formers, use appropriate liing equip‐
ment to remove from crate and carefully
suspend boom surface approximately
12” above the floor. Inspect lower rails
and mounng holes. Install the provid‐
ed rubber vibraon isolaon grommets
along with 5/16”‐18 bolts and fender
washers in each of the four mounng
holes (see Figure 4). Then carefully li
and posion the transformer above the
corresponding holes in the upper trans‐
former mounng shelf at the top of the
backbox. Carefully lower transformer

Wiring
 Isolated Power Systems require a single‐phase, 3‐wire incoming power feed (H,H,G
or H,N,G). Verify that the incoming voltage matches the Primary Voltage listed on
the isolaon transformer as well as the project drawings. Both of the incoming
power conductors are connected directly to the line side terminals of the Primary
Main Circuit Breaker. This 2‐pole breaker is sized to protect the isolaon transform‐
er windings. Terminate the incoming grounding conductor on the ground bus.
 The primary and secondary leads of the isolaon transformer are pre‐wired to the
main circuit breaker and panelboard lugs for IPP‐P and IPX‐P type panels. Installer
must terminate the transformer leads for IPD‐P, and IPL‐P type panels. Carefully
review the project shop drawings for each panel to verify the proper transformer
rangs (kVA, primary and secondary voltages), and compare to the data label on the
front of the transformer. Note the wire designators on the label and at the end of
each lead. Connect the primary winding (H1/H2) to the load side of the primary
main circuit breaker. Connect the secondary winding (X1/X2) directly to the panel‐
board lugs and connect the transformer grounding lug to the chassis ground bus
with the provided green insulated conductor. Reference Figure 6 for typical connec‐
ons. For IPD‐P panels with dual secondary winding transformers, the secondary
leads (X1/X2 & X3/X4) will connect to secondary main circuit breakers instead of
directly to the panelboard. Be certain to connect the correct set of leads to the
correct side of the panel based on the winding voltage. Note that mis‐wiring the
transformer leads can create an extremely hazardous situaon and may cause
catastrophic damage to the panel as well as any connected equipment.
 Special low leakage wire should always be used for branch circuit wiring of isolated
power systems. Cross‐linked, polyethylene type insulaon with a dielectric constant
of less than 3.5, such as XHHW‐2 is highly recommended. Standard construcon
type wiring such as THHN may be used for the incoming primary feeds and equip‐
ment ground wires only. Refer to Informaonal Note No. 2 of NEC 517.160(A)(6).
 For installaons in Canada, PG LifeLink recommends the use of RW 90 XPLE type
wire for all branch circuit conductors. Refer to CEC Part 1 ‐Secon 24‐204(2)(b).
 As noted in the previous secon, the total length of branch circuit conductors fed
from each isolaon transformer should be kept as short as possible to minimize
accumulated leakage current of the system. The recommended maximum cumula‐
ve length for all branch circuits of each leg (L1 or L2) is 450‐500 feet per transform‐
er. Avoid unnecessary runs where possible, minimize the number of connecon
points, and limit addional “slack” conductor coiled up inside juncon and device
boxes.
 All Isolated Power System branch circuits are protected by two‐pole circuit breakers
because there is no grounded neutral on the secondary output side of the trans‐
former. Up to a maximum of 16 branch circuit breakers may be installed on each
transformer. Refer to Figure 6.
 The Naonal Electric Code (NFPA 70) requires isolated branch circuit conductor insu‐
laon to be colored orange and brown, with a disncve stripe running its length in
a contrasng color (other than white, green, or gray). Orange wires (L1) are con‐
nected to the upper pole of each branch breaker and to the silver terminal screw

Page 14 © 2023 POST GLOVER LIFELINK, INC. ‐All rights reserved
PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
(typical neutral side) of each NEMA receptacle in the circuit. Brown wires (L2) are
connected to the associated lower pole of each breaker and the brass terminal screw
(typical hot side) of each receptacle. Consistent polarity should be maintained
throughout the installaon. Reference NEC 517.160(A)(5) or CEC Part 1 24‐204(2)(c‐
d). See Figure 6 for a typical installaon wiring diagram.
 Do not use pulling compounds to lubricate inside of conduit. This will break down
the insulaon properes and raise leakage current. A dry talc powder may be used.
It is recommended to use conduit with a slightly larger diameter to ease wire pulling
and avoid damage to the insulaon. An interior coang of PVC may also be used.
Reference NEC 517.160(A)(6).
 Isolated power circuits must be kept separate from other circuits and may not share
conduit or raceway with non‐isolated circuits, or isolated circuits from another sys‐
tem. Reference NEC 517.160(A)(1).
 The grounding terminals of each receptacle and hardwired device fed from the sys‐
tem must be connected to the Reference Ground Bus inside Isolaon Panel. When
mulple panels serve the same room or space, they must be bonded together locally
with a minimum #10 AWG insulated equipment bonding conductor. This includes
circuits from panels installed outside of the room, as well as non‐isolated (grounded)
circuits present in the room. Reference NEC 517.13 , 517.14, and 517.19.

 Where listed, follow component manufacturer’s specified ghtening torque for all
circuit breaker and bus lug electrical connecons. Where component manufacturer
specs are not available, torque all electrical connecons according to the values
listed in Table 2.
 IPS Panels that include System Load Monitoring (SLM), Branch Circuit Load Monitor‐
ing (CLM), or Fault Locaon (FLS) opons have special requirements for roung
circuit conductors. The isolaon transformer H1 primary lead should be routed
through the System Load Monitor Current Transformer (CT). Refer to Figure 6.
 Panels that include the Fault Locaon System (FLS) and/or branch Circuit Load Moni‐
toring (CLM) opons also require special branch conductor roung by the installa‐
on contractor. Each system includes one or two CT bank assemblies capable of
monitoring up to eight branch circuits each. If both opons are selected, up to four
CT banks will be installed (two on either side of the panelboard). The outermost CT
banks monitor CLM load current while the inner banks are used for FLS to idenfy
the circuit where a ground‐fault has occurred. Both isolated branch circuit conduc‐
tors (L1 & L2) should be routed through the associated FLS current transformer.
While, only the L1 conductor is routed through the CLM current transformer. See
Figure 6 for more details. The equipment chassis will also include labels with in‐
strucons for wiring these devices.
 Panels with CLM and/or FLS include a set of DIN rail mounted fused dis‐connects.
These are located next to the CT Manager module above the main breaker.
 The Line Isolaon Monitor connecon harness and remote terminal block (TB‐
REMOTE) are pre‐wired and installed on the equipment chassis. The LIM will be
mounted to the front trim panel during the final steps of installaon. Refer to the
specific user manual for the LIM being installed for detailed informaon on the
proper installaon, wiring, operaon, and maintenance of the LIM, including any
remote annunciators or accessories.
 Wiring for low voltage remote annunciators and accessories should enter through
conduit at the top of the enclosure terminate on the appropriate poles of the Re‐
mote Terminal Block. Route and secure wires to maintain adequate separaon from
power conductors and terminals. Consult LIM User Manual for recommended type,
gauge, and length of remote wiring. When pulling and terminang remote wiring,
ensure that no conductors come in contact with the metal enclosure, conduit, or
earth ground. This can adversely affect operaon of the remote device as well as
the LIM.

Front Trim Installaon
 A stainless steel front trim assembly is
included with each panel. The trim is
shipped with a protecve film covering
the brushed finish surface. Store flat, and
fully support trim panel when liing. Also
avoid leaning cover against wall or other
vercal surfaces to prevent bowing,
which can result in permanent warping or
mis‐alignment of the inset hinged breaker
access door. Verify that the front trim
matches the installed backbox.
 Before installing front trim, locate trim
mounng hardware consisng of 1/4‐20
stainless steel truss head screws and
black clip‐on u‐nuts. Hardware is pack‐
aged with equipment chassis. Install u‐nuts
at each mounng hole locaon along the
perimeter of front flange of the backbox.
 Once equipment chassis installaon and
wiring is complete and all finished wall
surfaces have been applied, the front trim
can be installed. The trim is mounted to
the backbox via three fully‐concealed
compound slide‐hinges. This feature
allows qualified users to easily open the
enclosure for maintenance/tesng with‐
out an exposed hinge or seam.
 To install, first loosen thumb‐screws and
fully extend slides on each of the three
compound slide‐hinges along the leside
of the backbox. Slides are locked in re‐
tracted posion for shipment. Ensure
thumb‐screw on boom hinge drops into
lower cam posion to prevent the weight
of the trim plate pressing against finished
wall when open. See Figure 7.
 Litrim panel and align drop pins with
pivot holes at the end of each hinge slide.
Lower trim to engage pins with slides.
See Figure 8. Note that trim panel cannot
be open more than 90°. Forcing panel to
open further will damage hinges and
likely cause mis‐alignment. If necessary,
remove door completed by liing it offof the hinges for full access. Lay trim flat when
not installed on hinges. Repeat steps above for reinstallaon.

6. Operation
Refer to Line Isolaon Monitor instrucon manual supplied with panel for complete
system operaon guidelines.
System Startup ‐Aer system has been properly installed and all wiring connecons
have been verified, energize the Primary Main Circuit Breaker in the Isolated Power
System panel. The LIM will undergo the following inializaon process each me unit is
energized:
1. Aer power is applied unit will perform a “lamp test”, illuminang all LED indica‐
tors and segments, as well as signaling audible alarm. The LCD screen displays cur‐
rent firmware version and serial number of the unit. If any problem is noted with
LEDs or displays, or if the audible alarm signal is not present, contact technical
support.
2. Aer “lamp test” is complete, the unit will enter self‐calibraon mode for approxi‐
mately 30 seconds. “Ca” is displayed on the LED screen, and the LCD display indi‐
cates “Status: Calibraon”.
3. Upon compleon of self‐calibraon, unit will enter normal operaon mode.
4. If this is the first me LIM has been energized, or if unit has been turned offfor
more than two weeks, a reminder to set the system me will appear. Refer to User
Menu secon of the LIM manual.
Normal Operaon ‐Under normal operang condions the LIM will exhibit the follow‐
ing:
1. The green “SAFE” indicator is illuminated, indicang unit is energized and condion

PG LIFELINK IPS PLUS Series Operaon and Maintenance Manual
© 2023 POST GLOVER LIFELINK, INC. ‐All rights reserved Page 19
is normal.
2. The red “HAZARD” and amber “SILENCED” indicators are exnguished. (Excepon:
if “Alarm Volume” has been set to “Mute” in the configuraon menu, the amber
“SILENCED” indicator will be connuously illuminated)
3. The 2‐digit mA display, along with the 16‐segment bar graph will indicate the calcu‐
lated Total Hazard Current for the Isolated Power System, including any connected
equipment.
4. The LCD display screen indicates “Status: System OK” along with the current me,
measured line‐voltage, and (if acvated) % of system full load.
THC Measurement ‐The primary funcon of the Mark V Line Isolaon Monitor is to
connuously monitor the line‐to‐ground impedance of both line conductors of a single
phase, ungrounded, Isolated Power System. A “fault” condion exists when a piece of
connected equipment causes this impedance to drop significantly, causing a proporon‐
al rise in the calculated Total Hazard Current (THC). When the THC exceeds the selected
alarm threshold value of 5 mA or 2 mA, audible and visual alarms are triggered on the
front of the LIM as well as on any connected remote annunciators.
System Load Monitoring ‐When installed and configured, the oponal System Load
Monitor (SLM) feature connuously displays the total system load current as a percent‐
age of the main breaker trip rang on the LIM’s user interface. Users can set a pre‐
alarm threshold value (default 80%) to nofy when system load is nearing breaker trip
point to avoid potenal overload and shutdown of panel. Refer to LIM manual for more
detailed informaon.
Circuit Load Monitoring ‐When installed and configured, the oponal Circuit Load Mon‐
itoring (CLM) feature connuously monitors the load current to each individual branch
circuit. A pre‐alarm value (default 80%) can be set for each circuit to nofy staffof po‐
tenal overload and loss of parcular branch circuit(s). When pre‐alarm is triggered,
relevant informaon is displayed on the LIM’s status screen. Status can also be ob‐
served via LEDs on the FLCLMS CT Manager module located behind the breaker access
door. Refer to LIM manual for more detailed informaon.
Fault Locaon System ‐When installed and configured, the oponal Fault Locaon Sys‐
tem (FLS) feature is automacally acvated whenever the measured THC of the IPS rises
above 4.8 mA, indicang the potenal of a line‐to‐ground fault on the system. The FLS
analyses each branch circuit and determines which one is contribung the highest incre‐
mental THC. The circuit number is idenfied on the LIM’s status display and also via
LEDs on the FLCLMS CT Manager. Refer to LIM manual for more detailed informaon.
