Introducon

The informaon provided in this manual covers three-phase 20kVA uninterrupble power systems, its basic func-

ons, operang procedures, opons available and emergency situaons. It also includes informaon on how to

ship, store, handle, and install the equipment. Only detailed requirements of the UPS units are described herein,

and installaon must be carried out in accordance with this manual. Electrical installaon must also carefully

follow local legislaon and regulaons. Only qualied personnel should conduct these installaons as failure to

acknowledge electrical hazards could prove to be fatal.

Product Descripon

Many dierent kinds of sensive electrical equipment can be protected by an Uninterrupble Power Supply (UPS)

including computers, workstaons, process control systems, telecommunicaons systems, sales terminals, other

crical instrumentaon, etc. The purpose of the UPS is to protect these systems from poor quality ulity power,

complete loss of power, or other associated problems.

Electrical interference exists in many forms, causing problems in AC power, from lightning, power company ac-

cidents and radio transmission motors, air condioners, and vending machines. Protecon of sensive electrical

equipment is vital to protect against power outages, low or high voltage condions, slow voltage uctuaons,

frequency variaons, dierenal and common-mode noise, transients, etc.

To prevent power line problems from reaching crical systems causing damage to soware, hardware, and equip-

ment malfuncons, the UPS maintains constant voltage, isolang crical load output and cleaning the ulity AC

power.

Main Features

This is a three phase input / three phase output high-frequency online UPS. The UPS protects against power fail-

ures, power sag, power surge, under-voltage, over-voltage, line noise, frequency variaons, switching transients,

and harmonic distoron which can all cause crical problems to supported sensive electronic equipment in the

market today.

Funcons and Features

• 3 phase input/output high-density UPS

• Digital Control

o The UPS is controlled by Digital Signal Processor (DSP) which increases reliability, performance,

self-protecon, self-diagnoscs, etc.

• Modular Design

• Baery Conguraon

o The baery voltage can be congured based on needs

• Charging Conguraon

o The charging current can be customized to meet site requirements

• Intelligent Charging Method

o 1st stage = high current constant current charging to restore baeries to 90% capacity

o 2nd stage = constant current charging to assure baeries remain fully charged

o 3rd stage = oat charge

The 3-stage charging method extends the life of the baeries and guarantees rapid recharging

• LCD Display

o Both LED and LCD displays allow for ease of use and availability of crical UPS status and opera-

onal parameters, including: input/output voltage, frequency and load %, baery %, ambient tem-

perature, etc.

• EPO Funcon

System Conguraon

The UPS device and the external baeries make up the system. Depending on the site and load requirements of

the installaon, certain addional opons are available for the soluon.

Planning a UPS system, the following should be taken into consideraon:

• The total demand of the protected system shall dictate the output power rang (VA). Allow a margin for

future expansion or calculaon inaccuracies from measured power requirements.

• Backup me required will indicate the baery size needed. If the load is less than the UPS nominal power

rang, then actual backup me is longer.

• The following opons are available:

o Connecvity Opons –SNMP/WEB card

o Extended Baery Packs - minimum 1 required

See the Specicaon secon of this manual for addional model informaon.

Unpacking the UPS

1. Do not lean the UPS against anything when moving it out of the packaging.

2. Check the physical appearance of the UPS to see if it was damaged during transportaon. Do not switch on the

UPS if damage is found. Please contact your dealer or distributor immediately for assistance.

3. Check the accessories according to the packing list to assure that you have all required pieces.

Installaon Notes

• Place the UPS in a clean, stable environment, avoiding vibraon, dust, humidity, ammable gas and liquid,

corrosive objects, etc. Check the operang temperature of the room where the UPS is being installed to

assure it is within range of UPS specicaon.

• Baeries should be installed in an environment where the temperature is within the required specica-

ons of the product. Temperature is a major factor in determining baery life and capacity. Normal baery

installaon requires the temperature be maintained from 15°C to 25°C. Keep baeries away from heat

sources and main air venlaon areas.

WARNING!

Typical baery performance data is quoted for an operang temperature between 20°C and 25°C. Operang

above this range will reduce the baery life while operaon below this range will reduce the baery capacity. If

the equipment is not to be installed immediately, it must be stored in a room so as to protect it against excessive

heat and humidity sources.

CAUTION!

An unused baery must be recharged every 6 months. Temporarily connecng the UPS to a suitable AC source and

acvang the UPS for the me required to recharge the baeries is required.

• To monitor the UPS with the soware, simply connect the RS232 cable to the UPS and to a computer.

External Protecve Devices

For safety reasons, it is necessary to install an external circuit breaker at the input AC ulity and to the baery.

External Baery

The UPS and its associated baeries are protected against the eect of over-current through a DC compable

thermo-magnec circuit breaker located close to the baery.
