Safety precautions
Operation
1. Before usingthis product, please read "safety precautions" carefully to ensure correct and
safe use, and please keep the manual properly.
2. Duringoperation, please pay attention to all warning signsand operate as required.
3. Donot use the device in direct sunlight,rain or the humidenvironment.
4. Thisequipment should not be installed near the heat source area or similar equipment such
as electric heater and hotstove.
5. A safe distance and ventilation should be reserved around the UPS. Please refer to the
manualfor installation.
6. Please use dry cleaning tools for wipingor cleaning the UPS.
7. In case of fire, please use the dry powder extinguisher correctly. There is a risk of electric
shockif 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 backuptime.
2. Battery maintenance canonly be carried out by personnel with battery expertise.
3. There is a risk of electric shock and short circuit in the batteries. Toavoid personal injury
caused byelectric shock,please observe the following warningswhen replacing batteries:
A. Donot wear watches, rings or similar metal objects;
B. Use insulated tools;
C. Wear rubber shoesand gloves;
D. Donot place metal toolsor similarparts on the battery.
E. Disconnectthe load from the batteries before removingthe battery connection terminal.
4. Please do not expose the battery to the fire for avoiding explosion and endangering the
safety of life.
5. Non-professionalsshould 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 goto the hospital for examination.
6. Please do not short-circuit the positive and negative poles of the battery, which may cause
electric shockor fire.
Use and maintenance
1. Theuse 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 placesexceedingthe 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 usedfor a longtime, the UPS(without battery) mustbe stored in a dry
environment at the temperature range: -15-60℃.Before starting UPS, the ambient
temperature mustbe warmed to 0℃above andmaintained for morethan 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 ACpower 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 supplystate.
Thismanual is applicable to the follow products, including:
6KS:Standard UPS with built-inoutput isolation transformer and batteries.
6KL:Longbackuptime UPS with built-inoutput transformer, which connects external batteries.
10KS:Standard UPS with built-inoutput isolation transformer and batteries;
10KL:Longbackuptime UPS with built-inoutput transformer, which connects external
batteries.

NOTICE:
Thisis a productfor restricted sales distribution to informed partners. Installation restrictions
or additional measures maybe needed to prevent radio interference.
Operate the UPS in an indoor environment only inan ambient temperature range of
0-40℃(32-104℉). Install it in a clean environment, free frommoisture,flammable liquids,
gasesand corrosive substance.
ThisUPS contains no user-serviceable parts except the internal battery pack. TheUPS ON/OFF
pushbuttons donot electrically isolate internal parts. Under no circumstanceattempt to gain
accessinternally, due to the risk of electric shockor burn.
Donot continue to use the UPS if the panel indications are not accordance with these
operating instructionsor the UPS performance alters in use. Reflect all faults to your dealer.
Servicing of batteries should be performedor supervised by personnel knowledgeable of
batteries andthe precautions.
Keepunauthorizedpersonnel away from the batteries. Proper disposal of batteries is required.
Refer to your local laws and regulations for disposalrequirement.
DONOTCONNECTequipmentthat could overload the UPS or demand DC current from the
UPS, for example:electric drills, vacuumcleaners, laser printers, hair dryer or any appliance
usinghalf-waverectification.
Storing magnetic mediaon top of the UPS may result in data loss or corruption.
Turnoff and isolate the UPS before cleaning it. Use only a dry cloth, never liquid or aerosol
cleaners.
