Owner’s Manual

1.0 scope

This manual provides technical information re-

quired for the installation, operation, and main-

tenance of the

EPS-2000m

Uninterruptible Power

Supply (UPS) System. Please read this manual

thoroughly before installing or operating the

EPS-

ZOOOW

equipment. The manual is divided into

four sections:

Section I

Introduction

This section serves as an introduction to the

manual and the

EPS-2000~

series

of UPS

products rated 10 to 40

kVA.

The UPS system

is described, followed by specifications for

standard models, an introduction to controls

and indicators, and a description of available

options.

Section II

Installation

This section explains procedures for receiving.

handling, and storing the equipment,

prerequisites to the installation procedure, in-

stallation, and equipment start-up procedures.

Introduction

Section

Ill

Operation

This section describes the

EPS-2000m

System

Status and Control Panel

(SSKP),

including

programmable controls and indicators. electro-

mechanical controls. UPS operating modes, and

system

alsrm

conditions.

Section IV

Maintenance

This section describes preventive maintenance

procedures, diagnostic capabilities of the UPS

system, and includes a listing of replacement

parts for the various UPS models.

In the rear of the manual is a glossary which

provides definitions for terms used within the

text. An Index makes it easy to find topics

of interest.

UPS Single Line Diagram

1.1 System Description

The

EPS-2000~

is an on-line static uninterrup

tible

power supply (UPS) system, designed to

protect critical loads from anomalies normally

encountered on a building’s power distribution

system. The

EPS-2000m

UPS and its auxiliary

equipment can be installed in a computer room

or an equipment room. Figure 1 is a pictorial of

the

EPS-2000TH

UPS System.

The

EPS-ZOOOW

UPS and its auxiliary equip-

ment are listed by Underwriter’s Laboratories,

Inc. (UL).

Major components of the

EPS-2000m

include a

Rectifier/Battery Charger, a transistorized pulse

width modulated (PWM) Static

Inverter,

a con-

tinuous duty rated Static Switch which automati-

cally transfers the load to and from the bypass

AC input source and the UPS

lnverter

output,

an internal Maintenance Bypass function which

is comprised of three separate switches that

allows the critical load to be operated from the

utility source while the UPS output is isolated

for service, and a battery system housed in an

external matching enclosure.

A System Status

Control Panel

(SS&CP)

pro-

vides controls to select system operation, and

indicators which 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 to assist in troubleshooting. The

built-

in EPS Monitor software is programmed to dis-

play messages in five languages

English,

French, German, Spanish, and Italian.

The EPS-2000” uses microprocessors to pre-

cisely control operation of the Rectifier/Battery

Charger, transistorized pulse width modulated

(PWM) Static

Inverter,

and Static Switch to in-

sure optimum performance for all line, load, and

operating conditions. In addition, a micropro-

cessor-based diagnostic system assists in trouble-

shooting faulty assemblies for replacement, to

minimize service time. Modular construction

throughout the

EPS-2000m

UPS facilitates main-

tenance of the system.

A single-line diagram of the EPS-2000”” UPS

system is shown in Figure 2. The location of the

EPS-2000m

UPS major internal elements is

shown in Figure 3A (10. 15.
