Safety precautions
Operation
1. Before using this product, please read "safety precautions" carefully to ensure correct and
safe use, and please keep the manual properly.
2. During operation, please pay attention to all warning signs and operate as required.
3. Do not use the device in direct sunlight, rain or the humid environment.
4. This equipment should not be installed near the heat source area or similar equipment such
as electric heater and hot stove.
5. A safe distance and ventilation should be reserved around the UPS. Please refer to the
manual for installation.
6. Please use dry cleaning tools for wiping or cleaning the UPS.
7. In case of fire, please use the dry powder extinguisher correctly. There is a risk of electric
shock if a liquid fire extinguisher is used.
Electrical safety
1. The battery life is shortened with the increase of ambient temperature. Regular battery
replacement can ensure the UPS to work normally and provide sufficient backup time.
2. Battery maintenance can only be carried out by personnel with battery expertise.
3. There is a risk of electric shock and short circuit in the batteries. To avoid personal injury
caused by electric shock, please observe the following warnings when replacing batteries:
A. Do not wear watches, rings or similar metal objects;
B. Use insulated tools;
C. Wear rubber shoes and gloves;
D. Do not place metal tools or similar parts on the battery.
E. Disconnect the load from the batteries before removing the battery connection terminal.
4. Please do not expose the battery to the fire for avoiding explosion and endangering the
safety of life.
5. Non-professionals should not open or damage the battery, because the electrolyte in the
battery contains dangerous substances such as strong acid, which can cause harm to the skin
and eyes. If you accidentally touch the electrolyte, immediately wash it with plenty of water
and go to the hospital for examination.
6. Please do not short-circuit the positive and negative poles of the battery, which may cause
electric shock or fire.
Use and maintenance
1. The use environment and preservation method have influence on the service life and
reliability of this product. Please do not use it in the following working environment:
A. High, low temperature and humid places exceeding the technical
specifications(temperature 0-40℃, relative humidity 20%-90%).
B. Places with vibration and vulnerable to collision.
C. Places with metal dust, corrosive substance, salt and combustible gas.
2. If it is not used for a long time, the UPS(without battery) must be stored in a dry
environment at the temperature range: -15-60℃. Before starting UPS, the ambient
temperature must be warmed to 0℃above and maintained for more than 3 hours.

1. Introduction
This series of UPS is an online sine wave uninterruptible power supply system with bypass
maintenance switch, which can provide reliable and high-quality AC power for your precision
equipment. It can be used in a wide range, from computer equipment, communication system
to industrial automatic control equipment. Because of its online design, it is different from the
backup ups. It continuously adjusts and filters the input voltage. When the power supply is
interrupted, it will provide the backup power from the backup battery without time
interruption. In case of overload or inverter failure, the UPS switches to the bypass state and
be powered by the mains. If the overload is cleared, the UPS will automatically switch back to
the inverter power supply state.
This manual is applicable to the follow products, including:
6KS: Standard UPS with built-in output isolation transformer and batteries.
6KL: Long backup time UPS with built-in output transformer, which connects external batteries.
10KS: Standard UPS with built-in output isolation transformer and batteries;
10KL: Long backup time UPS with built-in output transformer, which connects external
batteries.

Warning: This is a product for commercial and industrial application in the second
environment-installation restriction or additional measures may be needed to prevent
disturbances.
NOTICE:
This is a product for restricted sales distribution to informed partners. Installation restrictions
or additional measures may be needed to prevent radio interference.
Operate the UPS in an indoor environment only in an ambient temperature range of
0-40℃(32-104℉). Install it in a clean environment, free from moisture, flammable liquids,
gases and corrosive substance.
This UPS contains no user-serviceable parts except the internal battery pack. The UPS ON/OFF
push buttons do not electrically isolate internal parts. Under no circumstance attempt to gain
access internally, due to the risk of electric shock or burn.
Do not continue to use the UPS if the panel indications are not accordance with these
operating instructions or the UPS performance alters in use. Reflect all faults to your dealer.
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the precautions.
Keep unauthorized personnel away from the batteries. Proper disposal of batteries is required.
Refer to your local laws and regulations for disposal requirement.
DO NOT CONNECT equipment that could overload the UPS or demand DC current from the
UPS, for example: electric drills, vacuum cleaners, laser printers, hair dryer or any appliance
using half-wave rectification.
Storing magnetic media on top of the UPS may result in data loss or corruption.
Turn off and isolate the UPS before cleaning it. Use only a dry cloth, never liquid or aerosol
cleaners.
