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.
