Owner’s Manual

Introduction

Scope

This manual provides technical information required for installation, operation, and maintenance

of the EPS-2000TM Uninterruptible Power System (UPS). Please read this manual thoroughly

before installing or operating the EPS-2000 equipment.

The manual is divided into four sections:

Section I -Introduction

This section serves as an introduction to the manual and the EPS-2000 family of UPS products.

The UPS is described; followed by specifications for standard models: and an introduction to

controls and indicators.

Section II

Installation

This section explains procedures for receiving. handling, and storing the equipment: prerequisites

to the installation procedure; installation: and equipment start-up procedures.

Section Ill -Operation

This section describes operation of the

EPS-2000

UPS, including the system status and control

panel

(SSKP).

programmable controls and indicators, electro-mechanical controls, operating

modes. alarm conditions, and isolation of the UPS.

Section IV

Maintenance

This section describes preventive maintenance procedures; EPS-2000 diagnostic capabilities;

remedial maintenance routines; and a listing of replacement parts.

In the rear of the manual is a Glossary that provides definitions for terms used within the text.

An Index makes it easy to locate topics of interest.

Uninterruptible Power System

1.1

General description

The EPS-2000 is an on-line static uninterruptible power system (UPS) designed to protect critical

loads from anomalies commonly encountered from power utilities. The EPS-2000 UPS and its

auxiliary equipment can be installed in a computer room or an equipment room. Figure 1 is a

pictorial of the EPS-2000 UPS.

The EPS-2000 UPS and its auxiliary equipment are Listed for Safety by Underwriter’s Laborato-

ries. Inc. (UL) under UL Standard 1778

Uninterruptible Power Systems.

Major components of the EPS-2000 include:

Rectifier/battery charger

rectifies ac input to dc for maintaining battery charge

Input autotransformer (optional)

matches input source voltage to that required

internally by the UPS

Transistorized pulse-width-modulated (PWM) static inverter

converts dc from

the rectifierlbanery charger (or from the battery when in battery operation mode)

to ac output voltage to maintain attached critical loads

Output transformer (optional)

provides the required output voltage for

attached loads

Continuous-duty rated static switch

automatically transfers between bypass

source and

inverler

output

External battery system

stores energy for utilization by the inverter (and attached

loads) in the event that utility ac input power is lost or of unacceptable quality

A system status and control panel

(SSSCP)

provides controls to select system operation. and

indicators that allow system performance to be monitored. A liquid-crystal display (LCD) is used

to display system operating parameters; provide step-by-step operating instructions to the system

operator; and provide a diagnostic capability with instructions to assist in troubleshooting.

The built-in EPS monitor software is programmed to display its messages in any of five (5)

languages

English, French, German, Spanish, and Italian.

The EPS-2000 uses microprocessors to precisely regulate operation of the rectifier/battery

charger. transistorized pulse-width-modulated inverter, and static switch, to assure optimum

performance for all line. load. and operating conditions. In addition. a microprocessor-based

diagnostic system helps troubleshoot faulty assemblies within the EPS-2000 UPS, to minimize

time required to restore system operation in the unlikely event of an internal UPS fault. Modular

construction throughout the EPS-2000 UPS facilitates maintenance of the system.

A single-line diagram of the EPS-2000 UPS is shown in Figure 2. The location of major internal

components within the EPS-2000 UPS is shown in Figure 3.

The EPS-2000 100 and 125

kVA

UPS are 480 VAC input, 480 VAC output devices. The

EPS-

2000 50-80

kVA

UPS are offer in 2081208, 2201220 or

4801480.

When different input

and/or

output voltages are specified, external transformers provide the step-up and/or

step-down

func-

tions as required. These transformers

are housed

in auxiliary cabinets, either an ACA-2000 or

SDC-2000 or both.

In addition to housing voltage matching transformers, each of these auxiliary

cabinets can house optional equipment as well.
