Chapter 1 Introduction
The Powerware®9390 Integrated Accessory Cabinet (IAC) is designed for use with the
Powerware 9390 40–80 kVA and 100–160 kVA three-phase uninterruptible power systems
(UPSs). The IAC provides maintenance bypass, parallel tie cabinet, or parallel tie cabinet
with maintenance bypass functions with the following custom configurable features,
enabling adaptation and expansion without costly electrical rework:
쑺Maintenance Bypass Configuration – Maintenance Bypass (MBP) and Maintenance
Isolation (MIS) breakers enable power to completely bypass the UPS power module. The
UPS module can then be safely serviced or replaced without interrupting power to
critical systems. An optional Bypass Input Breaker (BIB) and Rectifier Input Breaker (RIB)
provide a single wiring point input to the UPS as well as a convenient method for
removing power from the UPS when using the maintenance bypass to supply the load.
쑺Parallel Redundant Configuration – Module Output Breakers (MOB) 1 and 2 enable two
UPS modules to be paralleled together for redundancy. An optional System Load
Breaker (SLB) provides output control to the critical load for the whole system.
쑺Parallel Redundant Configuration with Maintenance Bypass – Module Output Breakers
(MOB) 1 and 2 enable two UPS modules to be paralleled together for redundancy.
Optional Maintenance Bypass (MBP) and Maintenance Isolation (MIS) breakers enable
power to completely bypass the UPS power module.
The IAC is housed in a single, free-standing cabinet, with safety shields behind the doors
for hazardous voltage protection. The cabinet matches the UPS cabinet in style and color,
and can be installed in line-up-and-match or standalone configurations. Figure 1-1 shows
the Powerware 9390 IAC.

1.4 Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that should be followed during installation and
maintenance of the IAC. Please read all instructions before operating the equipment and save
this manual for future reference.
The IAC is designed for industrial or computer room applications, and contains safety shields
behind the doors. However, the UPS system is a sophisticated power system and should be
handled with appropriate care.
DANGER
This UPS system contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY.ThereareNO USER SERVICEABLE PARTS inside
the UPS.
WARNING
쑺The UPS system contains its own energy source (batteries). The output terminals may carry
live voltage even when the UPS is disconnected from an AC source.
쑺To reduce the risk of fire or electric shock, install this IAC in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature
must not exceed 40°C (104°F). Do not operate near water or excessive humidity
(95% maximum). The system is not intended for outdoor use.
쑺Ensure all power is disconnected before performing installation or service.
CAUTION
쑺Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
쑺Keep the IAC doors closed to ensure proper cooling airflow and to protect personnel from
dangerous voltages inside the unit.
쑺Do not operate the UPS system close to gas or electric heat sources.
쑺Maintain the operating environment within the parameters stated in this manual.
쑺Keep surroundings uncluttered, clean, and free from excess moisture.
쑺Observe all DANGER, CAUTION, and WARNING notices affixed to the inside and outside of

Chapter 2 IAC Installation Plan and Unpacking
Use the following basic sequence of steps to install the Integrated Accessory Cabinet (IAC).
1. Create an installation plan for the IAC (Chapter 2).
2. PrepareyoursitefortheIAC(Chapter2).
3. Inspect and unpack the IAC (Chapter 2).
4. Unload and install the IAC and wire the system (Chapter 3).
5. Complete the Installation Checklist (Chapter 3).
6. Have authorized service personnel perform preliminary operational checks and
startup.
NOTE Startup and operational checks must be performed by an authorized Eaton
Customer Service Engineer, or the warranty terms specified on page W-1 become void.
This service is offered as part of the sales contract for the UPS system. Contact service in
advance (usually a two-week notice is required) to reserve a preferred startup date.
2.1 Creating an Installation Plan
Before installing the IAC, read and understand how this manual applies to the system being
installed. Use the procedures and illustrations in the following chapters to create a logical
plan for installing the system.
2.2 Preparing the Site
For the IAC to operate at peak efficiency, the installation site should meet the
environmental parameters outlined in this manual. If the IAC is to be operated at an
altitude higher than 1500m (5000 ft), contact your Eaton service representative for
important information about high altitude operation. The operating environment must
meet the weight, clearance, and environmental requirements specified in Drawing
164201590-2 on page A-6 and the size requirements specified on Drawing 164201590-8
starting on page A-63.
The IAC uses natural convection cooling to regulate internal component temperature. Air
inlets are in the front of the cabinet and outlets are in the top (see Drawing 164201590-8
starting on page A-63). Allow clearance above, below, and in front of each IAC, for proper
air circulation. See Drawing 164201590-2 on page A-6 for clearances.

2.2.1 Environmental Considerations
The life of the IAC is adversely affected if the installation does not meet the following
guidelines:
쑺The system must be installed on a level floorsuitableforcomputerorelectronic
equipment.
쑺The system must be installed in a temperature and humidity controlled indoor area free
of conductive contaminants.
Failure to follow guidelines may void your warranty.
2.2.2 Preparing for Wiring the IAC
NOTE A minimum of two separate feeds with upstream feeder breakers, or one feed
with two upstream feeder breakers, must be provided: one for the UPS and one for the
IAC bypass input. DO NOT use one feed or a single feeder breaker to supply both the
UPS and IAC.
Power and control wiring for a line-up-and-match IAC are supplied with the cabinet.
Wiring requirements for an IAC installed separate from the UPS cabinet, including the
minimum AWG size of external wiring, can be found on Drawing 164201590-4 starting on
page A-19. The input power wiring connections for this equipment are rated at 90°C. If
wire is run in an ambient temperature greater than 40°C, higher temperature wire and/or
larger size wire may be necessary.IAC control wiring requirements can be found on
Drawing 164201590-7 starting on page A-56 and should be connected at the IAC interface
terminal block located inside the IAC.

EATON Powerware®9390 IAC-B and IAC-T Installation and Operation Manual S164201590 Rev C powerware.com
2.3 Inspecting and Unpacking the IAC
The cabinet is shipped bolted to a wooden pallet (see Figure 2-1) and protected with outer
protective packaging material.
CAUTION
쑺The IAC is heavy (see Table A on page A-6). If unpacking instructions are not closely
followed, the cabinet may tip and cause serious injury.
쑺Do not install a damaged cabinet. Report any damage to the carrier and contact your Eaton
service representative immediately.
쑺Do not tilt the IAC more than 10° from vertical or the cabinet may tip over.
1. Carefully inspect the outer packaging for evidence of damage during transit.
2. Use a forklift or pallet jack to move the packaged cabinet to the installation site,
or as close as possible, before unpacking. Insert the forklift or pallet jack’s forks
between the pallet supports on the bottom of the unit.
NOTE Verify that the forklift or pallet jack is rated to handle the weight of the cabinet
(see Table A on page A-6 for cabinet weight).

IAC Installation Plan and Unpacking
2-4 EATON Powerware®9390 IAC-B and IAC-T Installation and Operation Manual S164201590 Rev C powerware.com
3. Set the pallet on a firm, level surface, allowing a minimum clearance of 3m (10 ft)
on each side for removing the cabinet from the pallet.
NOTE The IAC is shipped with a debris shield covering the ventilation grill on top of
the unit. Do not remove the debris shield until installation is complete.
4. Remove the protective covering from the cabinet.
5. Remove the packaging material, and discard or recycle in a responsible manner.
6. Inspect the contents for any evidence of physical damage, and compare each item
with the Bill of Lading. If damage has occurred or shortages are evident, contact
your Eaton service representative immediately to determine the extent of the
damage and its impact upon further installation.
NOTE While waiting for installation, protect the unpacked cabinet from moisture, dust,
and other harmful contaminants. Failure to store and protect the IAC properly may
void your warranty.
