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 module uses electrostatic sensitive devices.
SPECIFIC
WARNINGS 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. 3-4, 3-11, 7-5)

OVERVIEW
I-E96-508C 1 - 1
SECTION 1 - INTRODUCTION
OVERVIEW
The INFI 90 DC input power system provides 5 VDC, ±15 VDC,
and 24 VDC to power process control modules and field termi-
nation devices. The DC input power system uses a 24 VDC or
48 VDC input as the system supply voltage.
The system consists of the power entry panel (PEP), fan assem-
bly, power modules and their mounting unit, bus bars and
associated wiring. The power modules provide scalable power
for logic and I/O functions through N+1 redundancy. In this
type of redundancy, power modules equally share output. If
any power module fails, the remaining power modules adjust
their outputs to meet the total system load. Therefore, redun-
dancy can be provided by one extra power module beyond the
minimum number required to power the system.
INTENDED USER
The user should have a background in electricity and electron-
ics and be able to recognize shock hazards. Personnel working
with the DC modular power system must also be familiar with
electronic process control instrumentation and how to use
measuring instruments such as digital multimeters.
HARDWARE DESCRIPTION
Power Entry Panel
The IEPEP04 Power Entry Panel supplies DC line power to the
system cabinet. The IEPEP04 panel transfers redundant power
to the system cabinet and monitors system status. It contains
the DC transfer module and the bus monitor module which
perform these functions. The DC transfer module monitors line
voltage inputs to the system cabinet, provides automatic DC
line transfer (for redundant DC lines) and generates a power
fail interrupt (PFI) signal. The bus monitor module monitors
the power system and provides status and user alarm outputs.
Fan Assembly
The fan assembly provides air flow cooling for the power mod-
ules and process control modules in the system cabinet. The
IEFAN03 fan assembly is used in 24 VDC powered systems
and the IEFAN05 fan assembly is used in 48 VDC powered
systems.

INTRODUCTION
FEATURES
1 - 2 I-E96-508C
®
Power Modules
There are four power modules: the IEPDS01 System Power
Module and IEPDF01 Field Power Module require 24 VDC
inputs, the IEPDS02 System Power Module and IEPDF02 Field
Power Module require 48 VDC inputs. The IEPDS01 and
IEPDS02 modules provide 5 VDC, ±15 VDC and 24 VDC out-
puts. The IEPDF01 and IEPDF02 modules provide only 24 VDC
output for field powered devices.
Module Mounting Unit
The IEMMU01 Module Mounting Unit provides the housing,
power connections and signal conductors for power supply and
process control modules. The IEMMU02 Module Mounting Unit
has the same functionality as the IEMMU01 Module Mounting
Unit, but it is a front-mounted unit. Its primary use is in
smaller system cabinets like the MINI 90™ system.
Power Mounting Unit
The power mounting unit (PMU) segregates power modules
from INFI 90 process modules. It provides housing and power
connections for IEPDS01 or IEPDS02 and IEPDF01 or
IEPDF02 power modules. The PMU is capable of supporting up
to 12 power modules (provided that its output current capacity
of 100 amps is not exceeded).
There are two PMU models. The IEPMU01 Power Mounting
Unit is a rear mount unit, the IEPMU02 Power Mounting Unit
is a front mount unit. Both PMU units mount in an INFI 90 or
Network 90 ®system cabinets.
FEATURES
The modular power system requires less cabinet space than
conventional systems, yet it offers features found on larger
power supply systems.
•The DC modular power system accepts redundant 24 VDC
input or redundant 48 VDC input. The DC transfer card in
the power entry panel automatically transfers the input
source if one source fails.
•Power modules provide scalable power for logic and I/O
functions through N+1 redundancy. With N+1 redundancy,
power modules equally share total power output. If any
module fails, the others adjust their output to meet the
total system load.

SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section uses block diagrams and supportive text to
explain how the main functional blocks of the power system
operate. Figures 2-1 and 2-2 show overall system architecture
using a module mounting unit and systems using a power
mounting unit. Additional diagrams show circuit details for the
DC transfer module, bus monitor module and power module.
POWER DISTRIBUTION
Bus bars distribute DC input and regulated DC output power
throughout the cabinet. The input power bus bar has three
separate conductor layers. The system power bus bar has eight
separate conductor layers. Bus bars reduce hand wiring and
improve reliability.

DESCRIPTION AND OPERATION
POWER DISTRIBUTION
2 - 2 I-E96-508C
®
The input power bus bar distributes DC power from the power
entry panel (PEP) to the module mounting unit (MMU) back-
planes. The bus bar has quick connect tabs to connect cables
from the power entry panel and the module mounting unit.
IECAB03 cabinets have power mounting units (PMU) and do
not have input power bus bars. A cable distributes power
directly from the PEP panel to the PMU card cage (see
Figure 2-2).
The eight-layer system power bus bar distributes regulated DC
voltages, power supply status and power fail interrupt (PFI) sig-
nals. This bus bar also has quick connect tabs.
High-current, multi-conductor flat cables connect regulated
voltage outputs and status signals from the MMU backplane to
the system power bus bar. A cable from the power entry panel
to the system power bus bar allows the system to monitor bus
voltages and status signals. Extra tabs are available at the bot-
tom of the system power bus bar for connecting 24 VDC I/O
power to field termination units or to other cabinets. Tabs are
also available to connect DC common and I/O common to the
system common bus bar at the bottom of the cabinet.
