Preface
The INFI 90®OPEN Modular Power System II supplies 5, 15,
-15, 25.5, 48 and 125 VDC power to an INFI 90 OPEN cabinet.
This power system can operate on 120/240 VAC or 125 VDC
input power. This power system is a direct replacement of the
Network 90™power system and INFI 90 modular power system
in their entireties. Components of the Network 90 power sys-
tem or the INFI 90 modular power system cannot be used with
INFI 90 OPEN Modular Power System II components. The
INFI 90 OPEN Modular Power System II fits in the same cabi-
net space as an INFI 90 modular power system that uses a
power mounting unit. Benefits of the modular power system II
are power factor correction, on-line replaceable components,
and improved monitoring functions that are selectable. The
system can operate in either an N, N+1 or N+x configuration or
2N configuration.
This instruction provides information on modular power sys-
tem II installation, operation, maintenance and troubleshoot-
ing. Anyone installing or operating the modular power system
should read and understand this instruction.

Safety Summary
GENERAL
WARNINGS Equipment Environment
All components, whether in transportation, operation or storage,
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to insure that contact with
energized parts is avoided when servicing.
Special Handling
This device uses electrostatic sensitive devices.
SPECIFIC
WARNINGS Insure the fan blades have stopped rotating before removing the
fan assembly from the fan chassis. Removing an operating fan
assembly exposes rotating fan blades that can cause injury. (p. 3-6,
7-5)
Verify the main power and power entry panel circuit breakers are
turned off before starting installation, retrofit, upgrade, or wiring pro-
cedures. Failure to do so could result in severe or fatal shock. Do
not turn the power on until the installation, retrofit, upgrade, or wiring
procedures are complete. (p. 3-10, 3-14, 7-6, 7-9, 7-11, 7-14)
There are exposed AC and DC connections inside the cabinet.
These exposed electrical connections present a shock hazard that
can cause injury or death. (p. 6-3)
If input or output circuits are a shock hazard after disconnecting sys-
tem power at the power entry panel, then the door of the cabinet
containing these externally powered circuits must be marked with a
warning stating that multiple power sources exist. (p. 6-3)
Never clean electrical parts or components with live power present.
Doing so exposes you to an electrical shock hazard. (p. 6-5)
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using com-
pressed air, injury to the eyes could result from splashing solvent as
it is removed from the printed circuit board. (p. 6-5)
Allow 30 seconds for the line filter capacitors to discharge before
handling the module after removal. Failure to do so could result in
severe or fatal shock. (p. 7-3, 7-4, 7-11)
Handle the module by surfaces other than the heat sink. The heat
sink may be hot and may cause severe burns. (p. 7-4)

Sommaire de Sécurité (suite)
AVERTISSEMENTS
D’ORDRE
SPÉCIFIQUE
(SUITE)
Si des circuits d'entrée ou de sortie sont alimentés à partir de
sources externes, ils présentent un risque de choc électrique même
lorsque l'alimentation du système est débranchée du panneau
d'entrée d'alimentation. Le cas échéant, un avertissement signalant
la présence de sources d'alimentation multiples doit être apposé sur
la porte de l'armoire. (p. 6-3)
Des lunettes de protection devraient être portées lors de travail
avec des solvants nettoyants. Lorsqu'on enlève les solvants des cir-
cuits imprimés à l'aide d'air comprimé, les éclaboussures de solvant
pourraient causer des blessures aux yeux. (p. 6-5)
Allouer 30 seconds pour permettre aux capaciteurs filtres de ligne
de se décharger avant de manipuler le module après l’avoir retiré.
Un manquement à cette précaution pourrait causer un choc sévère
ou fatal. (p. 7-3, 7-4, 7-11)
Le module doit être manipulé à l'aide de surfaces autres que le dis-
sipatour thermique. Ce dernier risque d'être chaud et de provoquer
des brûlures sérieuses. (p. 7-4)
ATTENTIONS
D’ORDRE
SPÉCIFIQUE
Ne pas installer les modules d’alimentation de champ IPFLD48 et
IPFLD125 dans le même châssis IPCHS01. CECI causerait des
dommages à l’équipement. (p. 2-3, 3-23)

mounting unit. Components of the Network 90 power system
and INFI 90 OPEN modular power system cannot be used with
components of the INFI 90 OPEN Modular Power System II.
This system is designed to operate in several configurations of
power module redundancy (N, N+1, N+x or 2N). Benefits of the
INFI 90 OPEN Modular Power System II are:
•Power factor correction.
•On-line replaceable components.
•Improved monitoring functions.
•Directly accepts 125 VDC inputs.
INTENDED USER
This instruction is written for engineers, technicians and sys-
tem designers as a source of technical information on the INFI
90 OPEN Modular Power System II. This instruction should be
used by those planning to purchase, install, operate, trouble-
shoot, maintain or replace this power system. Those working
with the power system should have experience working with
and know the precautions to take around AC/DC power. A
knowledge of how to use basic electronic test equipment (digi-
tal multimeter), and electrical and electronic principles is also
required.
POWER SYSTEM DESCRIPTION
The INFI 90 OPEN Modular Power System II consists of a power
module chassis, fan chassis, power entry circuit breakers or
switches, system fans, system power modules, field power
modules and a power monitor module.
System Power Module
The IPSYS01 System Power Modules are rack mounted circuit
boards that supplies 5, 15 and -15 VDC system voltages, and
25.5 VDC I/O power to an INFI 90 OPEN cabinet. The system
power module can accept 120/240 VAC or 125 VDC input
power. The AC inputs have active power factor correction to
greater than 0.95. Current sharing circuitry enables the sys-
tem power modules to equally share output current. The mod-
ule monitors the DC/DC converters and power factor corrector
and displays the status on five red/green faceplate LEDs. The
system power module mounts in one power module chassis
mounting slot.
Field Power Modules
The IPFLD01 and the IPFLD24 Field Power Modules are the
same as the system power module except that they output 25.5
VDC field I/O power only at 143 watts and 286 watts respec-
tively. The IPFLD48 and IPFLD125 field power modules output

INTRODUCTION
POWER SYSTEM DESCRIPTION
I-E96-542B 1 - 3
49.1 VDC and 125.6 VDC respectively. The field power mod-
ules have the same power factor correction and internal moni-
toring circuitry. There are only two red/green LEDs on the field
power modules: one for the DC to DC converter status and one
for the power factor corrector status. The field power module
mounts in one power module chassis mounting slot.
NOTE: IPFLD48 and IPFLD125 field power modules cannot be
installed in the same IPCHS01 power module chassis.
Power Monitor Module
The IPMON01 Power Monitor Module monitors system level
and status input functions, which include:
•All system bus voltages (5, 15, -15 VDC) and I/O bus volt-
age (25.5 VDC, 48 VDC and 125 VDC).
•Two selectable auxiliary inputs for 24, 48 or 125 VDC
external sources.
•Two cabinet temperature monitor inputs.
•One power fail interrupt (PFI) alarm that can be configured
for latching or nonlatching.
•Two logic level status inputs. These contact logic inputs
can be selected to accept normally open (N.O.) or normally
closed (N.C.) contact inputs.
•Three isolated outputs for bus alarm, power alarm,
and I/O alarm.
•One power system status output for use on Plant Loop or
INFI-NET®communication networks.
•Two fan status inputs.
•One power supply status signal from each power module.
•The status of power monitor module internal circuitry.
This power monitor module mounts in the center power mod-
ule chassis slot. The power monitor module faceplate has three
red/green LEDs to indicate power monitor module status and
AC/DC input power lines status. Eight additional LEDs are
used to show the state of status inputs. There are six test
points that accept a voltmeter probe for checking 5, 15, -15
and 25.5 VDC bus voltages (two test points are system com-
mon and I/O common). The power fail interrupt (PFI) reset
pushbutton is used to reset a PFI signal when the PFI latched
option is enabled.

Power Module Chassis
The IPCHS01 Power Module Chassis provides power input,
power output bus bars, and various terminals for status
inputs, outputs and mounting of up to eight power modules
and one power monitor module. There are nine mounting slots
total. The center slot is dedicated to the power monitor module.
Four slots on each side of the power monitor module hold
power modules and have isolated power inputs. All the power
module outputs share the same bus. System power for the cab-
inet is made available at bus bars on the power module chassis
backplane and at one of the terminal strips (for ±15 VDC).
Cables connect the bus bars and terminals to the system
power bus bar for distribution to the cabinet. Power modules
and the power monitor module can be removed from the power
module chassis and replaced while the system is on-line. Only
IPSYS01, IPFLD01, IPFLD24, IPFLD48 or IPFLD125 power
modules and the IPMON01 power monitor module can be
mounted in the power module chassis.
NOTE: The IPFLD48 and the IPFLD125 power modules cannot be
mixed in the same power module chassis at the same time.
Power Entry Circuit Breaker or Switch
The IPECB11 or IPECB13 Power Entry Circuit Breaker and
IPESW11 or IPESW13 Power Entry Switch terminate the AC/
DC power input lines and provide line filtering before feeding
power to the power module chassis backplane. These devices
are mounted on the rear of the power fan chassis. One circuit
breaker or switch is used on N, N+1, or N+x redundant systems
(Fig. 1-2); two are used on 2N redundant systems (Fig. 1-3).
The isolated inputs on 2N redundant systems allow use of
mixed power inputs (i.e., 125 VDC and 120/240 VAC) because
two separate power entry circuit breakers or switches feed iso-
lated power inputs to the power module chassis.
Fan Chassis and System Fans
The IPFCH01 Power Fan Chassis mounts two system power
fans. There are three types of fans in the INFI 90 OPEN Modu-
lar Power System II structure:
•IPFAN11 Power System Fan (120 VAC).
•IPFAN12 Power System Fan (240 VAC).
•IPFAN13 Power System Fan (125 VDC).
The fan chassis provides a power connection, fan monitoring,
and control via a cable connection to the power module chassis
backplane.

INTRODUCTION
POWER SYSTEM DESCRIPTION
I-E96-542B 1 - 5
The power system fans mount side-by-side in the fan chassis.
Hall effect sensors on the power system fans provide fan speed
information to the power monitor module. Fan speed is con-
trolled as a function of cabinet temperature. One fan is capable
of cooling the cabinet and a failed fan can be replaced while the
system is on-line.
