EPS-2000TY 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
ac source and inverler ac 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
l
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.

Owner’s Manual
Table 1 details the different auxiliary cabinets used for all possible input/output voltage combina-
tions. For example, if your configuration requires 208 VAC input and output, your system will
consist of an EPS-2000 UPS and two ACA-2000 cabinets. as shown in the table.
The EPS-2000 UPS is part of the modular EPS-2000 family which includes the EPA-2000 battery
system, the ACA-2000 auxiliary cabinet. and the SDC-2000 site distribution cabinet. and options
available for each of the modules. The EPS-2000 family provides unlimited flexibility in designing
and field-upgrading a power protection and distrfbution system to meet the requirements of any
facility. Your configuration may vary somewhat from the bass-line EPS-2000 UPS system de-
scribed in this manual. For examples of typical configurations, see Appendix 8. For further
information on the ACA-2000. BPA-2000, and SDC-2000. see the owner’s manual for each
particular module.

1 .I .2 input autotransformer (optional)
The input autotransformer is used to match the external ac source voltage to that required inter-
nally by the UPS. The input autotransformer. when supplied, is housed in an optional ACA-2000
auxiliary cabinet. Refer lo Table 1 and Appendix B.
1.1.3 Rectifier/battery charger
The EPS-2000 rectifier/battery charger consists of:
.
Main ac input circuit breaker (al) - the main ac input circuit breaker provides
mechanical isolation and electrical protection for the input to the EPS-2000 UPS
.
Power module -the power module is a plug-in unit that converts incoming ac power
to regulated dc output voltage. The regulation is carded out by controlling the con-
duction angles of the power module’s internal silicon-controlled rectifiers (SCRs).
allowing the rectifier/battery charger to supply a stable dc voltage (within f 1%). The
dc voltage is filtered by a capacitor bank
.DC shunt -the dc shunt monitors the battery charger current and provides data to
the EPS-2000 microprocessors to regulate the dc current at the desired level. Battery
current is normally limited to 10% of the Ampere-hour (Ah) rating of the battery string
1 .1.4 Static inverter
The static inverter consists of:
.
Power module -the power module is a plug-in unit used to chop the dc voltage (from
the rectifier/battery charger) to obtain the pulse-width-modulated (PWM) waveform at
the UPS output
lAC output filter-the ac output filter is used to achieve a computer-grade sinewave
output voltage waveform, with a total harmonic distortion (THD) of 2% maximum
1 .I .5 Static switch
In the event of an internal failure of the UPS, the static switch provides for continued support of
the attached load(s) by switching the flow of current around the rectifier/battery charger and
inverter (see Figure 2. Single-Line Diagram). During overload conditions, the static switch
likewise uses the main ac input as a source of fault-clearing current, by switching around the
rectifier/battery charger and inverter. The static switch is fully automatic and its operation is
transparent to the user.
1 .I .6 Output transformer (optional)
The output transformer is used to match the internal inverter output voltage to that required. if
other than 208.220 or480 VAC. When supplied. it is housed in either the ACA-2000 auxiliary
cabinet, or the SDC-2000 site distribution center. Refer to Table 1 and Appendix 8.

The emergency Power off (EPO) keye are to be used during emergency
situations only, where a hazard to pereonnei or equipment exists, such
t
as during a fire. DO NOT USE THE EPO TO TURN THE UPS ON OR OFF;
follow the procedurea listed in Section iii -OPERATION, for turning on
end off the rectifier/battery charger and inverter.

Detailed descriptions of the SS&CP controls and indicators, their operation, and operation of the
EPS monitor software are provided in Section iii - OPERATION.
1.2.2 Circuit breaker
The main ac input circuit breaker (al) is located inside the EPS-2000 enclosure, and can be
accessed by opening the right front enclosure door. Ql serves to connect and disconnect the
EPS-2000 UPS from its input power source.
Your configuration may have additional circuit breakers and non-automatic switches housed in
optional modules such es the ACA-2000 auxiliary cabinet, the BPA-2000 battery system, and
the SDC-2000 site distribution cabinet. See the manuals for the respective module to learn
more about the controls located in these cabinets. See also Appendix B for typical EPS-2000
system configurations.

Current: Refer to Table 2. UPS output current at specified nominal output voltage
Power Factor: 0.8 lagging
Overload
characteristics: Applies to the UPS output when operating from either the bypass or the
UPS inverter output:
125% for 10 minutes

Overloads in excess of 150% or exceeding the overload time periods
previously indicated will cause the load to be transferred from the UPS
invener output to the bypass, provided that the two sources are synchro-
nized. Once the load is transferred to the bypass source after exceeding
the time periods previously indicated. the timed periods will start again for
operation on the UPS static switch. If the load does not return to less
than the unit’s full load rating prior to completing the timed overload
periods. the load will be disconnected.
Dynamic
characteristics: Peak voltage deviation on the UPS inverter output is listed below for the
conditions indicated:
50% step load change. f 3% maximum
