Chapter 1 Introduction
93E 30ITC
93E 60ITC
The Eaton® Integrated Transformer Cabinet (ITC) provides voltage transformation and isolation for the
93E 20–30 kVA and 40–60 kVA Uninterruptable Power Supply (UPS) to enhance the usability and reliability of
the systems. Two models are available, the 93E 30ITC and 93E 60ITC to match the installed Eaton 93E UPS.
A 480/208 Vac input isolation transformer provides an isolated input to the UPS rectifier for applications that
require an input of 480 Vac.
An optional 208/480 Vac output isolation transformer provides an isolated output to the critical load or for
applications that require 480 Vac. To save space, the transformer is contained in the same ITC as the input
transformer.
The ITC is housed in a single free-standing cabinet with a safety shield behind the door for hazardous voltage
protection. The cabinets match the UPS cabinet in style and color.
Figure 1-1 shows the Eaton 93E 30ITC and Eaton 93E 60ITC.
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. Contact an
Eaton service representative in advance (usually a two-week notice is required) to
reserve a preferred startup date.

Introduction
1.1 Installation Features
The ITC is designed to be installed in a line-up-and-match or standalone configuration. In a line-up-and-match
configuration power wiring may be routed either external to the cabinet using conduit or the power terminal
wiring channel assembly may be utilized to pass wiring between adjacent cabinets. In standalone
configurations power wiring is routed using external conduit.
To reduce installation time, wiring enters the ITC from the back and is routed to the front panel for easy
connection to the mechanical lugs located on the input and output circuit breakers.
A line-up-and-match ITC is installed adjacent to the UPS or other accessory cabinet. The recommended
installation location is to the left of the UPS cabinet. See Figure 1-2 and Figure 1-3 for line-up-and-match
configuration views.
1.2 Model Configurations
The following model configurations are available:

Chapter 2 Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS
DANGER
WARNING
CAUTION
This manual contains important instructions that should be followed during installation and
maintenance of the UPS system and batteries. Read all instructions before operating the
equipment and save this manual for future reference.
The UPS system is designed for industrial or computer room applications, and contains safety
shields behind the door and front panels. However, the UPS system is a sophisticated power
system and should be handled with appropriate care.
This UPS system contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the
UPS.
l
The UPS system is powered by its own energy source (batteries). The output terminals may
carry live voltage even when the UPS is disconnected from an AC source.
l
To reduce the risk of fire or electric shock, install this UPS system in a temperature and humidity
controlled, indoor environment, free of conductive contaminants. Ambient temperature must
not exceed 30C (86F). Do not operate near water or excessive humidity (95% maximum). The
system is not intended for outdoor use.
l
As a result of the connected loads, high leakage current is possible. Connection to earth ground
is required for safety and proper product operation. Do not check UPS system operation by any
action that includes removal of the earth (ground) connection with loads attached.
l
Ensure all power is disconnected before performing installation or service.
l
ELECTRIC ENERGY HAZARD. Do not attempt to alter any UPS system or battery wiring or
connectors. Attempting to alter wiring can cause injury.
l
Installation or servicing should be performed by qualified service personnel knowledgeable of
UPS and battery systems, and required precautions. Keep unauthorized personnel away from
equipment. Consider all warnings, cautions, and notes before installing or servicing equipment.
l
Keep the Accessory cabinet doors closed and front panels installed to ensure proper cooling
airflow and to protect personnel from dangerous voltages inside the unit.
l
Do not install or operate the UPS system close to gas or electric heat sources.
l
The operating environment should be maintained within the parameters stated in this manual.
l
Keep surroundings uncluttered, clean, and free from excess moisture.
l
Observe all DANGER, WARNING, and CAUTION notices affixed to the inside and outside of the
equipment.

Chapter 3 Installation Plan and Unpacking
Use the following basic sequence of steps to install the Eaton 93E 30 or Eaton 93E 60 Integrated Transformer
Cabinet (ITC):
1. Create an installation plan for the ITC (Chapter 3).
2. Prepare your site for the ITC (Chapter 3).
3. Inspect and unpack the ITC (Chapter 3).
4. Unload and install the ITC, and wire the system (Chapter 4).
5. Complete the Installation Checklist (Chapter 4).
6. Have authorized service personnel perform preliminary operational checks and start up the system.
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. Contact an
Eaton service representative in advance (usually a two-week notice is required) to
reserve a preferred startup date.
3.1 Creating an Installation Plan
Before installing the ITC, read and understand how this manual applies to the system being installed. Use the
procedures and illustrations in this section to create a logical plan for installing the ITC. This section contains
the following information:
l
Physical features and requirements, including dimensions
l
Power wiring installation notes
l
Location of conduit and wire entry landing plates
l
Location of power terminals
3.2 Preparing the Site
For the UPS system to operate at peak efficiency, the installation site should meet the environmental
parameters outlined in this manual. If the UPS system is to be operated at an altitude higher than 1500m
(5000 ft), contact an Eaton service representative for important information about high altitude operation. The
operating environment must meet the weight, clearance, and environmental requirements specified for the
applicable accessory cabinet.
3.2.1 Environmental and Installation Considerations
The UPS system installation, including the ITC, must meet the following guidelines:
l
The system must be installed on a level floor suitable for computer or electronic equipment.
l
The system must be installed in a temperature and humidity controlled indoor area free of conductive
contaminants.
Failure to follow guidelines may void your warranty.
The ITC operating environment must accommodate the weight requirements shown in Table 3-1 and the size
requirements shown in Figure 3-1 through Figure 3-6.

The 93E 30ITC uses forced air cooling and the 93E 60ITC uses convection cooling to regulate internal
component temperature. Air inlets are in the front of the cabinet and outlets are in the back of the cabinet. Allow
clearance in front of and in back of the cabinet for proper air circulation. The clearances required around the
ITCs are shown in Table 3-2.
