Chapter 1 Introduction

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:

l

93E 30ITC for use with the 93E 30 kVA UPS

1.3 Using This Manual

This manual describes how to install the ITC. Read and understand the procedures described to ensure

trouble-free installation and operation.

Read through each procedure before beginning the procedure. Perform only those procedures that apply to the

UPS system being installed or operated.

1.4 Conventions Used in This Manual

This manual uses these type conventions:

l

Bold type highlights important concepts in discussions, key terms in procedures, and menu options, or

represents a command or option that you type or enter at a prompt.

l

Italic type highlights new terms where they are defined.

l

Screen type represents information that appears on the screen or LCD.

Chapter 2 Safety Warnings

IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS

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.

DANGER

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.

WARNING

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 30C (86F). 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.

CAUTION

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.

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.

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.

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.

The basic environmental requirements for operation of the ITC are:

- Recommended Operating Range: 15–25C (59–77F)

- Maximum Relative Humidity: 95%, noncondensing

The ITC cooling requirements are shown in Table 3-3.
