HOW TO USE THIS MANUAL
Page iv
BP+15-150,2.9X
5/95
A proper understanding and use of this operating and maintenance manual will
enhance UPS system reliability. Therefore, the manual should be given equal status
with the tools and equipment used to align and maintain the system. Conversely,
improper understanding or application of the principles set forth can result in impaired
system operation, loss of power to critical equipment loads, injury to personnel and/or
damage to the UPS.
The following guidelines will assist in the understanding and use of this manual.
1. Become familiar with the Table of Contents. It is here that the user can
first determine where in the manual required information or guidance can be
found.
2. Read through the entire manual so as to become familiar with its style and
general contents.
3. Know the manual’s limitations. It is not the intent of this manual to give a
detailed theory of operation of the UPS system. Troubleshooting is limited to the
isolation and correction of problems that are signaled by the Control!
Monitoring/Alarm Panel.
4. Be thoroughly familiar with the safety precautions outlined in Sections II
and IV of the manual.
5. Do not take short cuts when operating the UPS or performing mainte-
nance on the system. A slower, more deliberate pace will give better results
because it eliminates confusion and any false conclusions which may be reached
by skipping steps. Careful adherence to step sequences presented herein is, more
often than not, the fastest way to achieve desired results.
6. This manual is written based on the assumption that maintenance
personnel will be fully knowledgeable in electronics and aware of the hazards of
working with high voltage equipment. Always remember that voltages may be
present even when the system has been fully shut down. Use a voltmeter to check
terminals to ground. There is no substitute for common sense.
7. Don’t guess! If you don’t know, ask someone who does.
8. Remember that the International Power Machines Service Staff is always
available to answer your questions or provide helpful advice about your UPS
system. Call them on our Service Hot Line:

Handling and Unpacking Instructions
Page v
BP+15-150,2.9X
5/95
Handling Instructions:
1. Cabinets should always be stored in an upright position. Failure to observe this precaution can cause serious damage and
cancellation of warranty.
2. Cabinets should be forklifted only at appropriate lifting points. Make sure that forks are long enough to go entirely under the unit
and protrude from the other side. Be careful not to puncture another unit beyond the one being lifted.
3. Chains, cables, ropes or other retaining devices should not be wrapped around a cabinet. The weight of the system is great
enough to cause collapse of the cabinet when lifted by these means.
4. Padding must be used when transporting the system so as to help prevent damage to the cabinets.
Inspection and Unpacking Instructions:
The uninterruptible power system (UPS), battery pack cabinet and/or power distribution unit (PDU) is thoroughly checked, both
electrically and mechanically, before shipment from the factory. With the extensive protection provided in packaging the unit for
shipment, it should be in proper condition upon receipt. However, there is a possibility that the unit might have been damaged in
transit so a complete inspection of the equipment should be made before signing receipt. As a minimum, the following inspection
procedures should be executed as soon as possible after delivery.
Receiving / Unpacking lnspection Checklist
5. Each palletized unit is designed for forklift or lift gate handling. It is recommended that all packaging be left intact until the unit
is in close proximity to its final location to prevent incidental damage during movement.
6. Inspect the exterior packaging for obvious damage such as punctures or gashes that are indicative of damage to the unit. If
evidence of damage exists, save the packaging material for inspection by the carrier when a claim is filed. Request for inspection
should be made immediately.
7. Strapping should be cut and the corrugated cap and/or sleeve carefully removed. Remove padding and plastic sheeting. The
cabinet then may be unbolted from the shipping pallet.
8. Inspect each cabinet: check all exterior surfaces for scratches, chips, cracks and/or indentations. Check monitoring panels
carefully.
9. If door key is needed, locate key envelope taped to rear of cabinet. Open each door, checking for damage.
10. A label on the outside of the UPS tells the location of the Operations & Maintenance (O & M) Manuals.
11. Remove any internal padding/packaging, checking carefully for parts, documentation, etc., that might have been shipped inside
the cabinet. If foam
12. blocks are inside the battery trays, leave them in place. The are to keep small batteries from moving around inside the trays.
Damage Documentation
It is the responsibility of the recipient to file claim with the carrier for damages to the equipment or notify IPM, depending on the
f.o.b. point. Any and all damage noted upon receipt of the UPS, battery pack and/or PDU should be clearly identified in detail on the
Bill of Lading. Carrier’s claim procedures should be initiated promptly. In the event damage is found after delivery, it should be
reported as soon as possible (normally, there is a 15 day time limit on reporting damages incurred in shipment).

SECTION I
Theory of Operation
Page 1.1
BP+ 10-150

1.1 General
The BalancedPower Plus® (BP+) Uninterruptible Power System (UPS)
presented in this manual is a solid state, on-line system designed to provide high
quality, continuously filtered and conditioned ac power to computers, their
peripherals and/or other critical equipment loads. Most commonly, the UPS is
configured as a single, stand-alone unit. Fifteen (15) power ratings are available
from 10 to 300 kVA. Information contained herein is applicable to all power ratings
except where specified otherwise.
A single UPS is comprised of the following basic components:
Input transformer
Rectifier/Charger
Inverter
Static Bypass Switch
Bypass Breaker
Output Transformer
System Control Logic and Circuitry
Digital Monitoring Panel
Battery
DC Disconnect
A one-line diagram in Section II shows the relationship of these various
components.
1.2 Rectifier/Charger
The UPS input voltage from the utility is fed into the rectifier/charger
(usually referred to as the rectifier) which converts the ac to filtered, regulated dc
voltage. The dc is used to power the inverter and to recharge the batteries as
necessary. The assembly consists of an input circuit breaker, a transformer, and a
solid-state three-phase rectifier designed to eliminate even ordered harmonics. An
optional input filter reduces harmonics caused by rectifier switching. This prevents
the harmonics from affecting utility distribution.

SECTION I
Theory of Operation
Page 1.2
BP+ 10-150
2/95
1.3 Inverter
The inverter changes dc voltage to precision ac voltage through pulse width
modulation (PWM) inversion. Output isolation transformers and an output filter
provide “clean”, computer grade ac which is then sent to the critical load. When
utility power is available, the rectifier supplies power to the inverter. Should the
utility power fail, the inverter is powered by the batteries for a predetermined length
of time.
1.4Static Bypass Switch
The static bypass switch connects the UPS bypass input to the load in the
event of the loss of the inverter output or an overload condition. During normal
conditions, the static bypass switch is in the open or disconnected mode which
isolates the bypass input from the load.
If the inverter output becomes unavailable or exceeds its specified tolerance,
the static bypass switch will close and transfer the load directly to ac power
without interruption. This transfer is automatically inhibited in the event the UPS
bypass input is not within specified tolerance.
As soon as the inverter becomes available, returns to within tolerance or the
overload clears, the static bypass switch will disconnect and retransfer the load to
the inverter. Note, however, that so long as the inverter is out of specification, the
static bypass switch will automatically inhibit retransfer of the load.
1.5 Batteries
The optional battery pack supplies 216 VDC (10-30 kVA) or 360 VDC (37.5-
150 kVA) nominal. It can be attached to the UPS module to form a single unit or
may stand alone to accommodate space restrictions. It is the energy reservoir of the
UPS and provides dc power to the inverter in case of loss of UPS input power or
rectifier malfunction. The DC Disconnect (Battery) Circuit Breaker electrically
isolates the battery pack from the UPS module for maintenance purposes and
provides overcurrent protection at the battery output.

SECTION I
Theory of Operation
Page 1.3
BP+ 10-150
2/95
1.5 Batteries (continued)
The rectifier/charger normally provides a maintaining or “float” charge to
the batteries. Following periods of discharge when the batteries have supplied
power to the inverter, the rectifier/charger increases power to the batteries in order
to recharge them.
1.6 Control Logic and Control Circuitry
The control logic and circuitry of the UPS provide the operating logic and
system control for all functions ranging from limiting the rectifier/charger inrush
current by “walking” it in, to maintaining the inverter output voltage within rigid
specifications, to determining whether or not the static bypass switch should be
activated. The control logic is, for all practical purposes, the brain of the UPS.
1.7 Digital Monitoring Panel
The UPS is equipped with a standard Digital Monitoring Panel which
selectively monitors critical parameters of the UPS, using bright, easy-to-read
digital LED displays. In addition, detailed instructions guide the operator through
the UPS startup sequences. An alarm history can be called up on these digital
displays when desired.
In the event of an abnormal condition, an audible alarm sounds and the
corresponding red LED illuminates to identify the condition so that corrective
action can be taken. Alarm Silence and Emergency Power Off pushbuttons are
provided.
This panel is discussed in greater detail in Section III.

1.8 Multi-Level Passwords
A password is required to access and make use of the UPS Maintenance
Menu, described in Section 3.6.3. This menu, with five subsections, makes
possible the performance of a variety of maintenance functions including transfer
and retransfer to bypass, password changes and adjustment of time and date.
All passwords may be changed by a person who already knows either the
password in question or a higher level password.
Passwords consist of a minimum of 4 characters and a maximum of 9
characters. The numerals 0 through 9 and letters A through F may be employed.
The first character of the password indicates the privilege level of the
password. The higher the privilege level, the more capabilities that password can
access.
Privilege level 0: No password. Used for the front panel display of
voltages, currents, etc. only. Does not permit any
menus to be accessed.
Privilege level 1: Reserved for future development.
Privilege level 2: Remote operator password. Used to monitor the UPS,
but not to affect transfers and retransfers.
Privilege level 3: Reserved for future development.
Privilege level 4: Operator password. Monitors the UPS as well as
allowing transfers, retransfers, transfer enables,
retransfer enables, reset faults, etc.

1.9 Phone Home Alarm Reporting
When this UPS is activated for phone home operation and the UPS senses
one of several pre-selected alarm conditions, the UPS automatically dials IPM’s
Field Service computer without human assistance and notifies IPM’s Field Service
personnel of a system problem requiring attention.
Important information downloaded during each phone home event includes:
1) UPS name, ID and serial number, 2) customer ID and phone number and 3)
list of active alarms. You obtain the following benefits from this feature:
a. Immediate field service notification of site power or UPS problems,
even when the UPS is unattended.
b. Increased availability due to reduced mean-time-to-repair with
automatic notification and complete remote diagnostic capabilities.
c. 24-hours per day, 7 days per week monitoring of unmanned facilities
and locations where operators are unfamiliar with the UPS. Often,
service personnel can take steps to solve a UPS problem remotely
before the user is aware that there is a problem.
An internal modem and a dedicated telephone line are required. Phone
Home Alarm Reporting can be activated only with a Field Service level of password.
It is normally done at the time of startup by our Customer Engineer.
1.10 Dial-Back Security
This security feature is provided to insure system integrity. It prevents
“hackers” or other unauthorized persons from intentiona11y or unin-
tentionally accessing the UPS database. Anyone calling the UPS must
establish authority through the use of a dial-back password. The unit will
validate this password against up to four passwords stored in non-volatile
memory. One of the passwords will allow direct communication to commence
with the UPS. The other three passwords will have associated telephone
numbers. If one of these three passwords receives validation, the UPS logic will
hang up and dial back the phone number associated with that password. When
connection is made, the remote operator must enter the normal privilege level
password for access to the corresponding level of monitoring diagnostics and

SECTION I

2/95
1.10 Dial-Back Security (continued)
controls. In this way high level security is provided since the remote operator must
know the dial-back and access passwords and be calling from the proper
associated phone number.
An internal modem and a dedicated telephone line are required. Dial-Back
Security can be activated only with a Field Service level of password. It is normally
done at the time of startup by our Customer Engineer. Phone Home Alarm
Reporting and Dial-Back Security can share the same modem and telephone line.

2.1 General
Your International Power Machines BalancedPower Plus UPS is UL-listed
and designed for installation on the computer room floor. Its attractive computer-
like appearance and quiet operation eliminate any necessity of creating special
facilities to house the UPS and its battery component. Since all modern computer
rooms utilize environmentally controlled conditions, installation in such a locale
will normally suffice to meet the needs of the UPS.
In the event that computer room installation is not practical, the selection of
a location for the UPS is critical to the performance of the system and to the life
expectancy of its components. Failure to select a site which meets all requirements
specified in this section can result in excessive maintenance problems. For
environmental considerations, please see the Installation Information at the end of
this section.
Operating temperature range for batteries is 0°C to 40°C (32°F to 104°F).
Battery warranty is conditional upon application at or below 25°C (75°F).
Continuous operation above 25°C may reduce or void battery warranty.
The BalancedPower Plus battery pack supplied by International Power
Machines is listed by Underwriters Laboratories only for use with the
BalancedPower Plus UPS.
2.2 Mechanical Preparation of UPS
The UPS can be fully accessed from the front for operation and mainte-
nance. However, during installation the UPS and any accompanying battery
cabinets should be left at least two feet (61 cm) from the wall to allow access to the
rear. If optional top cable entry has been purchased, an area of at least three feet
(91 cm) is required at the right side for installation.
The following steps should be taken, in the order indicated:

panel on the bottom of the UPS by removing six (6) screws.
4. For optional top cable entry, remove the right side cover by removing
two (2) screws at the bottom (inside front and back) and lift the cover. Drill holes in
the appropriate conduit plate of suitable size for the cables to be inserted through
it, and replace the plate.
5. Fasten leveling feet (packed inside) to the four bottom corners of the
UPS cabinet. Access to the inside of the cabinet is not required. Refer to Figure 2-1.
(An optional pedestal mount may replace leveling feet and casters.)
a. First screw the leveling foot screw through the leveling plate.
b. Use two sets of 114-20 x 1” screw, flat washer and lock washer to
fasten the leveling plate to the bottom of the cabinet. Two threaded holes are in the
floor of the cabinet to receive them.
c. Screw in each leveling foot until it is a minimum of 0.75 in (1.9 cm)
above the floor level. Tighten locking nut to keep it there.
6. If an IPM battery pack is to be attached to the left side of the
UPS, perform this sequence. If the battery cabinet is not to be attached to the left
side of the UPS, skip Step 6.
a. Open the left-hand front door of the UPS. Remove eight (8) screws

If batteries are not provided in IPM cabinets, see Disconnect Installation
Drawing at the back of this section for wiring of separate circuit breaker and skip
this Section 2.3. For battery preparation refer to the battery manufacturer’s
manual.
IPM battery trays are shipped screwed to the shelf supports and should be
left fastened down.
1. Fasten leveling feet (packed inside) to the four bottom corners of the
battery cabinet. Access to the inside of the cabinet is not required. Refer to Figure
2-1. (An optional pedestal mount may replace leveling feet and casters.)
a. First screw the leveling foot screw through the leveling plate.

fasten the leveling plate to the bottom of the cabinet. Two threaded holes are in the
floor of the cabinet to receive them.
c. Screw in each leveling foot until it is a minimum of 0.75 in (1.9 cm)
above the floor level. Tighten locking nut to keep it there.
2. If an IPM battery cabinet is to be attached to the left side of the UPS,
remove the fiberboard shipping panels from the left side of the UPS and the right
side of the battery cabinet by forcing out the fasteners. Leave the red glastic panel
attached. It is recommended that the battery cabinet not be attached to the
right side of the UPS.
a. If more than one battery cabinet is used, the one with a disconnect
circuit breaker should go adjacent to the UPS. This is Battery Cabinet #1.
3. Remove each left battery cabinet cover by removing screws from the
inside front. Be very careful not to touch the screwdriver against the battery
terminals. Then pull side panel forward and lift to remove.
4. In each battery cabinet, cut the straps holding the top tray of batteries If
foam blocks are inside the battery trays, leave them in place. They are to keep
small batteries from moving around inside the trays.
