Thank you for selecting this uninterruptible power system (UPS). It
will
provide you with better protection for connected equipment.
Please read this manual！
！！
！
This manual provides safety, installation and operating instructions that
will
help you derive the best
performance and service life that the UPS has to
offer.
Please save this manual！
！！
！
It includes important instructions for the safe use of this UPS and
for
obtaining factory service should the proper operation of the UPS come into
question.
Please save or recycle the packaging materials！
！！
！

.
If the problem remains, please consult sales agent for service.
Is the Master power switched on?
Is the UPS plugged into a correctly working outlet?
Is the line voltage within the rating specified?
Is the fuse on the rear panel blown?
Is the UPS over loaded?
Is battery not fully charged? Dead battery? Charger failure?
Please provide the following information when calling for service.
1. Model number, serial number.
2. Date of the problem occurred, date of purchase.
3. Full description of the problem including load, LCD, and
alarm status,
installation condition, working environment, etc.
TROUBLE SHOOTING CHART
Problem Possible Cause
Action To Take
Front panel switch
in off position. Turn on switch.

CAUTION
The UPS contains voltages
that are potentially hazardous. All repairs
should be performed by qualified service personal.

The UPS has its own internal energy source (battery). The output
receptacles may be live even when the UPS is not connected to an AC
supply.
The UPS is suitable for computers and electronic equipment. And
not
suitable for electronic equipment with significant inductive loads, such
as motors & fluorescent lamps.

Be sure to operate within the power rating of the UPS. Below 1/2 or 1/3
of rated power is recommended for longer backup time & longer battery
life.
Do not place the UPS near excessive humidity, in direct sunlight
, or
close to heat-emitting sources.

If the UPS is out of order, please detach power cord and consult your
dealer right away. Do not remove cover if there is no serviceable part
inside.
The unit should be supplied by a
grounded source. Do not operate the
unit without ground source.
The socket-
outlet should be installed near the equipment and be easily
accessible.

Do not plug the UPS power cord into itself. That will result in a safety
hazard.

Installation should be performed by a qualified technician or electrician
in accordance with local electrical codes.

BATTERY FACTS
The battery is the only periodically serviceable parts in the UPS. An
expected life is approx. 3∼5 years. H
owever, frequent long discharges or
ambient temperatures above 80°F/26°C
will shorten battery life. Therefore, it
is recommended to replace the batteries every 3 years after initiating the
unit.
Recharge batteries every 3 months if it is not in use becaus
e it may cause
batteries over-drain.
WARNING
Only a qualified technician should replace the battery. Batteries have
high short-
circuit current capacity; mistakes in connecting or
disconnecting can cause connections to arc or weld and could cause
severe burns.
STORAGE
The UPS should only be stored if the battery is fully charged. Avoid storage
temperatures above 80°F/26°C
as battery life is significantly shortened.
Every 90 days remove the unit from storage and plug it in for 24 hours to
recharge the batte
ries. Batteries may be damaged if left in storage and not
recharged every 90 days.
IMPORTANT NOTICE
Please use same type and same rating of batteries for replacement.
Do not replace it with the battery that exceeds specified rating.

2. Normal Operation
There are two main loops whenAC Utility normal the AC ou
tput loop and the
battery charging loop. The AC output gets power from AC utility input and
pass through AVR to support power to load. In the same time, the AC utility
input is converted by AC/DC CHA and support charging power to charge
batteries.

INSTALLATION AND OPERATION
Upon receipt of the UPS, inspect the shipping carton for damage. If there is
any obvious damage, immediately report it to the selling dealer
or the
delivering carrier. If there is no damage to the shipping carton, unpack the
unit and inspect the unit for damage.
The UPS is designed for installation in a protected environment within a
temperature range from 32°F/0°C to 104°F/40°C and relative h
umidity of
0∼
90% without condensation. Do not block inlets and outlets. Install the
system in a location free from excessive dust and chemical fumes.
Check the identification label to verify the UPS voltage and power rating
match the available line voltage and load requirements.
Installation:
1.
Check if the main switch on the UPS front panel is in the off position and
insure that the voltage of the AC utility source corresponds to the
nameplate on the UPS rear panel.
2. Plug the power cable into the grounded socket. If indicators of LINE-
ON
& CUT-
OFF LCD light on, it mean AC power is normal, although UPS is
under CUT-OFF status, it still will automatically start to charge by itself.
3. Push the main switch, then the Load Level LCD will light up
for 2
seconds and CUT-OFF LCD will go off. The UPS will then be
ready
and start to work normally.
4. Connect your PC with UPS, and then
turn on PC. Be sure to check the
Load Level LCD indicator and DO NOT OVERLOAD it over 100%. To
simulate AC failure (Push UPS test switch) c
an help to insure whether
UPS is in good condition or not. It is designed to sound an
alarm every 3
seconds and with BACK-UP LCD light on when simulation starts.
If the
CUT-
OFF LCD is on, it means UPS fault or BATTERY fault. Then you
have to contact your local service center
5.
When battery approaches low level, alarm will beep every second until
auto shut down
6. The 4 conditions UPS will automatically shut down:
a. Battery low b. Short circuit
c. Overload d. UPS fault
