Chapter 1 Safety Information
Please read and follow bellow instructions carefully, otherwise personal injury or
equipment damage may happen. Please keep the manual for future use.
1. Do not reverse connect the positive and negative poles of the
battery;
2. Do not short circuit the positive and negative poles of the
inverter battery;
3. For indoor application only, Do not expose the inverter under
humidity and direct sunshine, and do not place it close to
heating or energized objects;
4. Please keep more than 10cm clearance around the inverter and
keep good ventilation;
5. Do not place any object on the inverter;
6. Do not spill any liquid into the inverter or place any alien object
in the inverter;
7. When backup a computer-load, please transfer to UPS Mode in
order to avoid the load re-starting;

Warning
1. Inverter contains hazardous voltage inside; please do not open
the enclosure. Only authorized technical personnel are allowed
to repair the inverter;
2. The battery circuit is not isolated from the input voltage circuit,
and there may be high voltage between the battery terminal and
ground. Therefore, please check if there is any high voltage
before repairing;
3. Even if the inverter input power is opened, the internal circuits in
the inverter may still connect to the battery and have potential
hazards, so be sure to disconnect the battery before
maintenance and repairing.

Chapter 2 Overview
2.1Applicable Scope
This inverter is an intelligent 1/1 phase pure sine-wave inverter specially designed
for the houses and office environment in the regions where the utility voltage is
unstable or low for a longtime or where power failure frequently happens. With
CPU intelligent control, the inverter has the features of wide input voltage, fast
battery charging speed, aesthetic appearance and high reliability. It is widely used
for household appliances and office equipment, such as TV sets, Disc Players,
manual electric drill, refrigerator, recorder, water dispenser, fan, illuminating lamps,
computer, exchange and server, and the power range is from 600VA to 5000VA.

3.2Mechanical Installation
3.2.1 Installation Location
Place the inverter on a dry flat surface with good ventilation and without direct sunshine,
and erosive gases. In addition, keep at least 10cm clearance around the inverter for
good ventilation and do not place any object on the inverter.
3.2.2 Wiring Description
1) Connect the battery to the battery input terminals of the inverter correctly: The
positive cable (red) is connected to the positive pole of the battery, and the negative
cable (black) is connected to the negative pole of the battery. Please note that the
battery voltage should match the rated voltage of the inverter.
2) Close the battery circuit breaker on the rear panel;
3) Plug the power cord of the inverter to mains outlet;
4) Plug the load (the electrical appliance) into the inverter’s output receptacle. Please
be sure the load capacity shall not exceed the rated power of the unit

ON, means the inverter
abnormal, and check if the
inverter is faulty, over load
or over temperature
according to the alarm
sound
If the alarm lasts for 2s and
repeats 4 times, this means
the output overload; If the
alarm lasts for 1s and
repeats 3 times, this means
the inverter over
temperature; If the alarm
continuously beeps, this
means the UPS has fault
such as output short circuit,
inverter damaged or
hardware failure.
