operation and long term reliability of the UPS. Please read this manual
thoroughly before attempting to unpack install, and operate the UPS.
1.1 WARNING
1. To reduce the risk of fire or electric shock, install UPS and
batteries in a temperature and humidity controlled indoor area
which is free of conductive contaminants.
2. Risk of electric shock, Do not remove cover. No user
serviceable parts inside. Refer servicing to qualified service
personnel.
3. Risk of Electric shock---- Battery circuit is not isolated from ac
input, hazardous voltage may exist between battery terminals
and ground. Test before touching.
4. Risk of electric shock. Hazardous live parts inside this UPS are
energized from the battery supply even when the input ac power
is disconnected.
5. To reduce the risk of fire, replace only with same type and rating
of fuse.
1.1 Important Safeguards
Your UPS has been engineered and manufactured to assure your
personal safety, but improper use can result in potential electric shock
or fire hazards. To maintain the safeguards incorporated in this unit
observe the following basic rules :
*Turn off and disconnect your UPS from the utility before
cleaning. Do not use liquid cleaners or aerosol cleaners. A
damp cloth may be used to remove any dust or smudges which
occur on the outer surface of your UPS.

7
*Do not install or operate your UPS near water.
*Do not locate your UPS on an unstable cart, stand or table.
*Move the UPS and its supporting cart, stand or table with care.
Quick stops, excessive force and uneven surface may cause the
UPS and its support to overturn.
*Openings on the sides of the UPS cabinet must not be blocked
or covered and air flow through the Openings must not be
obstructed.
*Your UPS should be operated only from the type of power
source indicated on the marking label. For operating form
battery power, refer to the operating instructions (Section -6).
*Follow all warnings and instructions marked on your UPS.

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

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.
