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 ensure 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. 3-2, 3-13, 7-6, D-1)
Do not remove the plastic covers on the module mounting unit back-
plane. These covers protect against accidental contact with AC volt-
age. Severe or fatal shock could result. (p. 3-9)
Allow five 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. 3-11, 7-5)
Handle the module by surfaces other than the heat sink. The heat
sink may be hot and may cause severe burns. (p. 3-12, 7-5)
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. 6-1)
Never clean electrical parts or components with the AC power on.
Doing so exposes you to a fatal electrical shock hazard. (p. 6-1)
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. 6-1)
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 blown off the printed circuit board. (p. 6-1)

SPECIFIC CAUTIONS Verify the line voltage select switch is properly configured before
energizing the power entry panel. Failure to do so could perma-
nently damage the PFI circuit board by exposing it to improper input
voltage levels. (p. 3-12)
AVERTISSEMENT
D'ORDRE
GENERAL
Environment de l'equipment
Ne pas soumettre les composants a une atmosphere corrosive lors
du transport, de l'entreposage cu de l'utilisation.
Risques de chocs electriques lor de l'entretien
S'assurer de debrancher l'alimentation ou de prendre les precau-
tions necessaires a eviter tout contact avec des composants sours
tension lors de l'entretien.
Precautions de manutention
Ce module contient des composantes sensibles aux decharges
electro-statiques.
AVERTISSEMENT
D'ORDRE
SPECIFIQUE
Assurez-vous que le disjoncteur d'alimentation principal et le dis-
joncteur de panneau d'entrée des alimentatoins sont éteints avant
de procéder à l'installation, à la mise à jour, à l'extension ou au
câblage, dans le but d'éviter les chocs sérieux et même mortels. Ne
rétablissez pas l'alimentation tant que ces procédures ne sont pas
terminées. (p. 3-2, 3-13, 7-6, D-1)
Ne retirez pas les couvercles de plastique situés sur le panneau
arrière du châssis de montage des modules. Ces couvercles con-
stituent une protection contre les contacts accidentels avec la ten-
sion c.a., qui risquent de provoquer des chocs sérieux et même
mortels. (p. 3-9)
Après avoir retiré le module, laissez les condensateurs de filtres
antiparasites se décharger pendant cinq secondes avant de
manipuler celui-ci, afin d'éviter les chocs sérieux et même mortels.

AVERTISSEMENT
D'ORDRE
SPECIFIQUE
(suite)
Le module diot être manipulé à l'aide de surfaces autres que le dis-
sipatour thermique. Ce dernier resque d'être chaud et de provoquer
des brûlures sérieuses. (p. 3-12, 7-5)
Cette armoire comporte des connexions c.a. et c.c. dénudées. Ces
connexions électriques présentent un danger d'électrocution pou-
vant entraîner des blessures ou la mort. (p. 6-1)
Il ne faut jamais nettoyer des piècesou des composants électriques
lorsqu'ils sont sous tension. Cedi présente un risque d'électrocution
fatale. (p. 6-1)
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 l'alimentation. Le cas échéant, un avertissement signalant
la présence de sources d'alimentation multiples doit être apposé sur
la porte de l'armoire. (p. 6-1)
Portez toujours des lunettes de protection lorsque vous utilisez des
solvants de nettoyage. L'aircomprimé servant à enlever le solvant
des cartes de circuits imprimés provoque des éclaboussures qui ris-
quent d'atteindre les yeux. (p. 6-1)
ATTENTION D'ORDRE
SPECIFIQUE Assurez-vous que l'interrupteur de sélection de la tension de ligne
est adéquatement configuré avant de mettre sous tension le pan-
neau d'entrée des alimentations. Toute négligence à cet égard ris-
que d'endommager de facon permanente la carte de détection des
coupures d'alimentation (PFI) en l'exposant à des niveaux
inadéquats de tension d'entrée. (p. 3-12)

OVERVIEW
I-E96-506B1 1 - 1
SECTION 1 - INTRODUCTION
OVERVIEW
The INFI 90 AC modular power system provides +5, +15, -15
and +24 VDC to power process control modules and field ter-
mination devices.
The system consists of the power entry panel, fan assembly,
power modules and their mounting unit, bus bars and associ-
ated wiring. The power modules provide scalable power for
logic and I/O functions. The user has the option of selecting
N+1 power 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, redundancy can be provided by
one extra power module beyond the minimum number
required to power the system.
HARDWARE DESCRIPTION
Power Entry Panel
The power entry panel supplies line power to the system cabi-
net. There are three versions: IEPEP01, IEPEP02 and IEPEP03
Power Entry Panel. The IEPEP01 panel is the basic version. It
has surge protection and power fail interrupt detection; how-
ever, it does not have circuit breakers or DC voltage monitoring
capabilities. The IEPEP02 panel has one circuit breaker and is
identical to the IEPEP01 panel. The IEPEP03 panel has addi-
tional features.
The IEPEP03 panel transfers redundant power to the system
cabinet and monitors system status. It contains the AC trans-
fer module and the bus monitor module that perform these
functions. The AC transfer module monitors line voltage inputs
to the system cabinet, provides automatic AC line transfer (for
redundant AC lines) and generates a power fail interrupt (PFI)
signal. The bus monitor module monitors the power system
and provides status and customer alarm outputs.
Fan Assembly
The IEFAN01 and IEFAN02 fan assemblies provide air flow
cooling for the power modules and process control modules in
the system cabinet.

INTRODUCTION
USER QUALIFICATIONS
1 - 2 I-E96-506B1
®
Power Modules
There are two AC power modules: IEPAS02 System Power Mod-
ule and IEPAF02 Field Power Module. The IEPAS02 module
provides +5, +15, -15 and +24 DC voltages. The IEPAF02 mod-
ule provides +24 VDC only for field powered devices.
The IEPAS02 and IEPAF02 modules replace the IEPAS01 and
IEPAF01 modules. Both sets of modules can be used in the
same cabinet. The IEPAS02 and IEPAF02 modules are compat-
ible with the IEPAS01 and IEPAF01 modules.
Power Mounting Units
The IEPMU01 and IEPMU02 Power Mounting Units are
designed to provide housing and power connections to the
power modules. The power mounting units can service up to
ten power modules.
Power mounting units segregrate power modules from process
control modules and are built to handle heavier currents. The
IEPMU01 Power Mounting Unit is a rear mounted unit. The
IEPMU02 Power Mounting Unit is a front mounted unit.
Module Mounting Units
The IEMMU01 Module Mounting Unit provides the housing,
power connections and signals for power supply and process
control modules. The module mounting unit is an alternative
to the power mounting unit.
The IEMMU02 unit has the same functionality as the
IEMMU01 unit, but it is a front mounted unit. Its primary use
is in smaller system cabinets like the MINI-90™ system.
USER QUALIFICATIONS
This manual is not a tutorial. Therefore, the user should have
training as an electrical technician. That is, the user should
know the basics of, and precautions for, working with AC/DC
voltages, and how to use various measuring instruments such
as digital voltmeters.
