Safety Instruction
1.Prohibition
1.1 There is high risk of electric shock from the UPS inside, so please do not open or
remove the casing or front panel unless it is operated by authorized technicians;
otherwise, your warranty becomes void as well.
1.2 Please contact and discuss with distributors before connecting the UPS to following
equipments
Medical equipments which have direct relationship with patients’ life
Equipments like elevators which may do harm to human beings.
Similar equipments as mentioned above
1.3 Don’t dispose of the battery with fire so as to avoid explosion
2.Safety notice
1) The output of the standard UPS with internal batteries may be energized even if the
UPS input is not connected to the utility.
2) Do disconnect the UPS input and make sure the UPS is complete off before moving
the UPS or re-configuring the connection; otherwise, there will be potential electric
shock.

3) For the sake of human beings’ safety, please well earth the UPS before starting it.
4) Working environment and storage way will affect the life time and reliability of the
UPS. Avoid letting the UPS work under following environment for a long time
Area where the humidity and temperature is beyond the specified
range(temperature 0 to 40 celsius degree, relative humidity 5%-95%).
Direct sunlight and location nearby heat
Area which can be crashed easily
Area with corrosive gas, flammable gas, excessive dust…etc.
5) Keep the ventilations in good conditions otherwise the temperature of components
inside UPS will be high and the component and UPS life will be affected.
6) It is forbidden to pour liquid or put any objects into the UPS.
7) Don’t use liquid extinguisher if there is a fire, a dry powder extinguisher is
recommended.
8) Battery life cycle will be shorter as environment temperature rise. Replacing battery
periodically can help to keep the UPS in normal status and assure backup time
required. Battery replacement should be done by authorized technician.
9) Keep the UPS in a dry area or environment if it will not be free of operation for a
long time. Storage temperature of the UPS with internal battery is -20℃~+55℃, and
extended backup model without internal battery is -40℃~+70℃.
10) Taking out the UPS or batteries from storage, it is recommended to connect them
with the utility for at least 12 hours per 3 months to avoid battery from over-draining.
11) Don’t open the battery, electrolyte inside will do harm to eyes and skin. Please use
plenty of clean water to wash if touching then go to see a doctor.
