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

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.
11
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.
17
* 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.
