2. INTRODUCTION

2.1 Purpose of your Uninterruptible Power System

(UPS)

This Uninterruptible Power System is designed to provide a continuous

supply of usable 220 Volt AC as power to computer and other

electronic equipments during irregularities or failures of commercial AC

power. The UPS protects against AC power line irregularities such as

blackouts, sags, spikes and electromagnetic and radio frequency

interference.

When commercial AC line voltage levels are acceptable, the UPS

operates with very high efficiency, filters noise and spikes before the

power is delivered to its load (s). Should the commercial AC

experience irregularities or fail completely, the UPS supplies a

continuous sine-wave AC load power by utilizing the battery-fed

inverter. The UPS will supply a load of 3000/5000/6000VA UPS from

its external battery bank. The UPS provides AC power protection,

allowing continued operating though most commercial power

disturbances and an opportunity to secure data and safely shut down

systems in the event of an extended outage.

2.2 FEATURES OF THE UPS

The UPS system is designed to provide commercial AC power

protection for computers, peripherals and equipment used in business,

office and laboratory environments. Their performance and features

have been designed to ensure the utmost in AC power protection for

the load (s) as well as ease of use and unobtrusive operation. The

features include :

* Detection of AC utility blackouts and sags

* Spike suppression

* Attractive office styling

* Automatic restart after low battery shutdown

* Easily accessible front panel controls

* Inverter overload protection

* Computer interface card

* Audible alarm

* Cold-start feature

* Optional shutdown software support.

* Built in input over voltage protection

2.3 Design Concept

The figure below shows the block diagram of the UPS.

BYPASS

INPUT RECTIFIER INVERTER STATIC SW OUTPUT TO

CRITICAL LOAD

ISO

TXR CHARGER

# - This shorting link is removed when connected

with separate bypass source.

BATTERIES

The input to the UPS is 230 V, single phase supply. This is converted into DC

power by the rectifier circuit for the inverter. The inverter in turn converts this

DC power into AC for the critical loads.

The batteries are independently charged from the input AC. In the event of

loss of input AC, the batteries takes over and feeds the inverter.

The static switch serves as a dynamic bypass and connects the input /

bypass supply in the event of inverter failure or overload.

3. INSTALLATION

WARNING : IMPROPER INSTALLATION WILL NULLIFY

WARRANTY

3.1 Unpacking and Inspection

When unpacking the UPS shipping carton you will find the following contents

and enclosed in a waterproof bag.

* The UPS itself

* User Manual

The spares part consists of the fuse for replacement when necessary.

Remove the unit from its shipping carton and examine it for damage or

moisture. Do not try to operate the UPS if it appears damaged. Save the

original shipping carton and contact your nearest sales office for instructions.

3.2 Locating the UPS

The UPS is designed to be a free standing unit and is intended to be located

in a controlled environment. Ensure that air flow through the openings is not

hindered or obstructed. Obstructing the free flow of air could cause the UPS

to overheat.

CAUTION : The UPS cabinet is not rated to support weight. Never

stock material or stand on the UPS. Never position the UPS

on its side or upside down.

3.3 CONNECTING THE UPS TO COMMERCIAL AC

IMPORTANT: The UPS shall be installed by qualified technician or

electrician in accordance with the electrical codes for the

area where it is installed and operated.

CAUTION: Ensure that the voltage and frequency of the input

AC power are within the specifications of the UPS

and that the combined loads do not exceed the total

power for the UPS.

IMPORTANT: Select the right power wire according to the

recommended wire selection table 1 (Page 14) and

connection diagram as per Figures 1 & 2 (Page 10 & 11).

DANGER : The unit should be supplied by grounded source.

DO NOT operate the unit without ground source.

CAUTION: High DC voltage present on the battery connector

when battery circuit breaker is turned on. DO NOT

touch these battery connectors.

CAUTION: Use digital multimeter (DMM) to make sure the

battery voltage and polarity is correct. Wrong polarity

will cause damage to UPS. For easy identification

the line and positive terminations are red in colour &

neutral and negative are black in colour.

CAUTION: DO NOT connect input wires of UPS to a 15 amp wall

receptacle. The input current requirements of the

UPS exceed the current rating of the wall receptacle.

Connect the UPS to an utility panel whose

current rating is suitable. It is highly recommended

that use of circuit breaker in the wiring system to

gain better protection.

All wiring for the UPS should be done by an qualified

electrical technician since high voltage may be

present.

Ensure that input circuit breaker and battery circuit

breaker are in off position before connecting input

wires and battery wires to UPS.

The connectors are located at the rear section of the UPS inside the lower

rear panel. The protective panel must be removed for access by loosening

the appropriate screws (see Page 13 Fig.3). Table 2 (in page 16) shows

input and output currents for each rated voltage.

Be sure to follow all pertinent local electrical codes when selecting the

wiring.

5. OPERATING INSTRUCTIONS

A. DETAILED PROCEDURE :

* Before proceeding with the operating instructions ensure that your

UPS has been installed correctly.

* The UPS equipment is provided with easy to use power cable snap on

connectors with 1/3 meter cable length. This is to facilitate quick and

easy installation and uninstallation at any point of time. The connectors

provided with the cable have a free end which should be terminated

by suitable lugs as required by the incoming distribution at site. Figure

- 1(Page - 10) shows the wiring diagram for the common bypass

configuration (default). Note the shorting connectors for BYP-L, U4 &

BYP-N, N4. This will connect the incoming utility as the bypass source.

Figure –2 (Page –11) shows the wiring diagram for separate bypass

connection. In this case the shorting connectors are to be removed

and the separate bypass output is to be connected BYP-L, BYP-N.

Caution : Do not connect any wires to U4-N4 in a separate bypass

configuration. This may lead to short circuit of the input

sources.

* After properly connecting the UPS to the utility, turn on the Input

isolator (on the back panel). The “LINE” and “BYPASS” indicators

should be lighted. This indicates that the UPS is being connected to

commercial AC power. Turn on the battery circuit breaker. This will

commence the battery charging.

* Press the “on/off” switch on the front panel. The inverter indicator will

start illuminating. Both “BYPASS” & “INVERTER” indicator will remain

ON for about 20 seconds. After 20 seconds later, the indicator

“BYPASS” will extinguish, the “INVERTER” indicator will continue to

illuminate. When the unit is in normal operation, the output will be

powered from the inverter of UPS.

* Cut off the input AC power (by turning off a breaker / switch on the

utility line, an audible alarm should start to sound intermittently

indicating a loss of incoming AC power. Now the output is supplied

from the battery source.

* Turn on the input AC power and connect load (s) to the UPS. Make

sure that the total load will not exceed the output rating of the UPS

terminals. The UPS will start beeping constantly and FAULT indicator

light if it is overloaded, overheated or low battery voltage is detected.

Disconnect the load and cut off input AC power in such a situation.

Switch of the battery breaker to isolate batteries.

* The UPS audible alarm should sound intermittently when the UPS is

operating from the battery source.

* Connect a normal load to the UPS. Turn on the power switch.

Disconnect the input power. Again the audible alarm should sound

intermittently. When the UPS is under the back-up mode, a battery

capacity sensitive beeping indicates the battery power status. It will

beep continuously when low battery status is reached. The UPS will

automatically shut down in one or two minutes to protect the battery

from over discharging under such condition.

CAUTION: The UPS has been provided with a high line transfer circuit

which will cut off the input to the rectifier if it exceeds 275

Volts AC. After initial start-up keep power continuously to

the unit for at least 24 hours to ensure batteries fully

charged. To ensure charging the batteries, the main circuit

breaker and the battery circuit breaker should be left in the

“ON” position. However, the front panel “ON/OFF” switch

can be used as daily run/standby switch. Note that the

output will still be connected to the bypass supply and

inverter will be off.

STORAGE INSTRUCTIONS :

1. Leave equipment connected to input power and turned on for 24 hours

prior to storage.

2. Turn off the main circuit breaker.

3. Store in a cool, dry environment (Below 80° F / 27°C)

4. Remove from storage and repeat step 1 for every 90 days.

SHORTING LINKS

3. Initially, connect only the input line, neutral and earth connection.

4. Switch ON the input isolator on the rear panel, the breaker on the left

side as seen from the back of the unit.

5. The fans should start running and the ‘AC’ & ‘BYPASS’ indications on

the front panel should be ON. Please check that two “shorting liks”

BYP-L, U4 & BYP-N, N4 are connected properly. Otherwise, the fans

will not start.

6. Check the DC voltage on the terminal ‘BAT+’ & ‘BAT-’ above (the last

two terminals on the extreme right on the rear panel). The reading on

a DC voltmeter should be greater than or equal to 220 V DC.

a) At this point, the front panel ‘ON/OFF’ switch should be switched ON.

The ‘INVERTER’ LED on the front panel will start glowing gradually to

full brightness. After this action in about 17 seconds clicking sound will

be heard, which will connect the output to the inverter.

b) The battery can now be connected and the battery isolator can be

switched ON now.

STARTING THE UPS ON BATTERY (BLACK START)

1. As per the above connection diagram, connect only the battery to the

UPS (Ensure that the batteries are in fully charged condition showing

DC voltage greater than 205 VDC for the entire bank).

2. Switch-on the battery breaker on the rear panel and the front panel

;ON / OFF’ switch. There will be no response from the UPS at this

stage.

3. Now, gently press the red switch on the rear panel. This is black start

switch which is a push button switch. This will initiate the internal

circuitry of the UPS to start on batteries.

4. The response seen from the UPS will be that the ‘INVERTER’ LED will

slowly start to glow. The fans will not start at this instant.

Approximately 17 seconds after this operation a clicking sound of the

relay will be heard. The fan will start to operate and output will be

available from the inverter.
