1.IMPORTANT SAFETY INSTRUCTIONS,
SAVE THESE INSTRUCTIONS
1.1 • This manual contains important instructions for Model UPS series that should
be followed during installation and maintenance of the UPS.
• Unplug the unit from the AC outlet and make certain of all switches are
in the “off”position before cleaning. Do not use liquid or aerosol
cleaners, use only a water dampened cloth for cleaning.
• Do not attempt to service this product by yourself. Opening or removing covers
may expose you to dangerous voltage. Return the unit to your dealer for proper
handling.
• The output receptacles may have high voltage even the unit is not connected to
wall power.
• If the fuse is opened, to reduce the risk of fire, replace only with the same type
and rating of fuse.
• Servicing of battery should be performed by personnel knowledgeable of battery
and the required precautions. Keep unauthorized personnel away from battery.

1.2 SAFETY
CAUTION:
lThis unit is should be installed from service personnel.
lThe equipment can be operated by any individuals with no previous
experience.
lThe socket-outlet shall be installed near the equipment and easily accessible.
lAttention, hazardous through electric shock. Also with disconnection of this
unit from the main, hazardous voltage still may be accessible through supply
from battery. The battery supply should be therefore disconnected in the plus
and minus pole through the from the outer enclosure accessible battery fuses
when maintenance of service work inside the UPS is considered.

2.1 SYSTEM DESCRIPTION:
This unit is a stand by uninterruptable power supply (UPS.), it can keep
computers or other critical equipments performing through power
disturbances and outages.
2.2 FEATURES:
• Utilizes microprocessor based controls, minimizes the dependency on
hardware, maximizes system flexibility and assures super reliability.
• Extremely compact in size, suitable for any available space.
• Unit can be TURNED ON any time with or without utility power.
Suitable for emergency applications, especially during utility power failure.
• Automatic frequency selection to mate with utility power.
• Two-Step battery charger (first with cyclic charging voltage; second with
stand by charge voltage) to prolong battery life and fully charge the battery.
• With actually overload protection both in line and battery mode.

This unit can be installed besides the computer or equipment, do not install it
in non-ventilated areas.
3.2 Unpacking
The following items are included in the carton
lUser’s manual.
lPower cord.
lUPS
3.3 Connecting the UPS
For UPS series: Use the power cord to connect the wall power (utility power)
and inlet socket. Connecting the power cord of your computer to the UPS
output receptacle.
3.4 Staring operation
3.4.1 Turn on the UPS by pressing switch on rear panel to “ON”position, the
LED will light up, if the line voltage is absent, the LED will be slowly

flash and buzzer will be slowly beeping.
3.4.2 Turn on the computer, if it is over loaded, the LED and buzzer will
rapidly flash and beep, you should check the power rating of the loaded
equipment then remove the less critical one. Generally, the total power
consumption of one set of personal computer (color monitor) will not
exceed the rating of this UPS.
3.4.3 Unplug the input power cord to test the UPS backup function.
The LED and buzzer will be slowly flash and beeping. The computer or
other equipment shall still work well, without any malfunctions or
reset action.
3.4.4 Reapply the line power to the UPS, the UPS shall return to line mode
in 2 seconds.
3.4.5 Keep line power applied continuously to the unit for at least 5 hours to
ensure battery is fully charged.
3.5 Backup operation
If the line power is outage or input voltage is too high or too low, the UPS
will transfer to battery mode. The back up time should be about 10 minutes
for one set computer, if the back up time is less than 3 minutes, and the UPS
have been long time charged, the battery is not good enough and better to
replace with a new one.
4MAINTENANCE
The unit is designed for years of trouble-free operation, so only a little maintenance
is required.

A few helpful hints:
-Periodically vacuum dust from ventilation openings.
-Occasionally wipe exterior with a damp cloth.
5TROUBLESHOOTING
