and avoiding any unnecessary damage of the battery.

•The UPS is specially designed for computer only and it should not be connected

with any inductive or capacitive load, like electromotor, daylight lamp, laser printer,

etc.

•The UPS is not suitable for being used in life support systems, because it may

have some problems and bring trouble to the life support systems. The

responsibility will be users', if they insist on using the UPS in life support systems.

•It is normal that the temperature of the UPS surface reaches up to 50℃when it is

in operation.

ENGLISH

•When AC fails and the “ON” button on the front panel is pressed, the UPS will

output voltage; if the “OFF” button on the front panel is pressed, the UPS will not

output voltage.

•It is forbidden to open the case, because there is danger with electricity. If there is

problem, please handle with the instruction of experts.

•It is forbidden to put container containing liquid inside on the UPS, because it will

cause danger of electric shock or fire when the UPS short-circuits.

or the dealer for help.

•As there is no overload protection of the UPS, it cannot be overloaded. Otherwise,

it would cause danger.

•It is strictly forbidden to place and operate the UPS in the following environment：

oPlace with inflammable gas or corrosive gas or much dust；

oPlace with very high temperature or very low temperature(above 42℃or

below

o0℃) or high humidity(above 90％) ；

oPlace with direct sunlight or near heater；

oPlace with strenuous vibration；

oOutside

•Please use dry powder fire extinguisher in case of fire; it is forbidden to use fluid

fire extinguisher because it will cause electric shock.

•Please put the socket near the UPS, in this way, it is convenient to disconnect the

socket and cut off power in case of emergency.

Attention! Please ground the UPS for safety purpose

3.0 Working Principle

3.1 In AC mode

When UPS is in normal working mode, AC goes through the filter and the harmful

waves are filtered. After that, AC charges the battery and meanwhile, passes UPS

AVR and the filter and provide power for the equipment.

ENGLISH

3.2 AC Failure

When AC fails, the battery will supply power to the inverter and then passes filter and

provide power for the equipment, ensuring the continuous power supply.

3.3 Connections of the UPS

The UPS has the following connections:

•1 RS232 serial port

•1 USB port

•Output connections

3.4 Battery and Charging:

•When the UPS is connected to AC, the charger will charge the battery fully in

about 10 hours.

•When the battery is used up, please turn off the UPS and charge the battery for a

least 10 hours when. Then turn on the UPS

4.0 Main Features

4.1 Unattended Operation

•Please connect the UPS to AC and press the ON button on the front panel, the

UPS is turned on and the AC outputs stabilized voltage.

•When AC fails, UPS will supply power to the equipment immediately. And when

the battery is used up, UPS will turn off automatically.

•When AC comes back, UPS will turn on automatically.

4.2 Protection

•Battery discharge protection: when the battery discharges and the UPS is in

inverter mode, the UPS will check and monitor the working status of the battery;

when the battery voltage drops to the limited lowest voltage, the inverter will turn

ENGLISH

off automatically and protect the battery; When AC comes back, the UPS will

turn on automatically.

•Short-circuit Protection: when the UPS is in inverter mode and there is shock or

short-circuit, UPS will output limited currency, protecting the UPS( When in AC

mode, the UPS will be protected first by input fuse and then transfers to the

inverter working mode).

4.3 Four Kinds of Alarm Function

•When AC fails, and the UPS supplies power, UPS will alarm once every 10

seconds and the beep stops about 40 seconds later.

•When the battery is nearly used up, the UPS will alarm automatically and the

beep frequency is once every 1 second.

•Overload, when the UPS is overloaded, UPS will alarm once every 0,5 second

•Fault, if there is a faulty operation of the UPS, UPS will alarm continuously.

4.4 Lock Phase Function

In AC mode, the UPS system automatically tracks AC phase and ensures that the

output wave form of the inverter is the same with AC voltage wave form. In this way, it

reduces the peak pulse and surge voltage to minimizes the interference and damage

to the equipment.

4.5 The Function of the Self-set Frequency

When the UPS is turned on for the first time, the acquiescence frequency is 50/60Hz;

when it is connected to AC, the frequency is automatically set to 50Hz or 60Hz in

accordance with AC.

5.0 LCD Display

The UPS is equipped with an LCD display. The display shows the following

information:

•Input voltage

•Output voltage

•The battery status/level

•Power usage in percent

•UPS status indication

•Low Battery indication

•Over load indication

ENGLISH

6.0 Installing the UPS

Follow the instructions below to connect the UPS:

1. Shut down the load (for example PC)

2. Put UPS on the proper position

3. Connect load (for example PC) to the UPS

4. Connect the serial or USB cable to the computer and to the UPS.

5. Plug the UPS power cable into a wall outlet.

SUGGESTION: This UPS is the power supply for the computer, monitor and hard

disk(CD) etc. It has a limited backup time for the load, so you'd better not connect a

printer or other equipment to it.

6. Press the ON/OFF button on the front of the UPS to turn it on. You will hear a

short beep.

Remark

：

1. Generally speaking, don't turn off the UPS so the battery keeps charging.

2. When AC fails the UPS will turn to battery mode. Please save important

documents in time.
