1 Safety Precautions
1.1 Precautions for Operating a UPS
When operating a UPS, observe the following precautions:
All repairs and operations should be performed by authorized service personnel only.
Ensure all power is disconnected before performing installation and service.
Components inside an uninterruptible power system (UPS) are not operable. Do not open
the UPS cover. Otherwise, electric shocks may occur, and the resulting UPS faults are
beyond warranty scope.
Before moving or reconnecting a UPS, disconnect the AC input and batteries and wait
about 5 minutes until the UPS is powered off. Otherwise, electric shocks may occur.
To ensure human safety and normal UPS operation, the UPS must be properly grounded
before use.
To ensure that a UPS has a long service life and trusted reliability, do not place it in the
following places for a long time:
− Places where the temperature and relative humidity are outside the specifications
(temperature: 0–40°C, relative humidity: 0%–95%)
− Places in direct sunlight or near heat source
− Places where a UPS is susceptible to vibrations and shocks
− Dusty places, or places where corrosive substances, salts, or flammable gases are
present
Please keep the air vents of the UPS unobstructed. Poor ventilation will increase the UPS
internal temperature, which will shorten the lifetime of the UPS components and even
the UPS.
Liquid and other irrelevant objects are strictly prohibited inside the UPS.
In case of fire, use dry chemical fire extinguisher to put out the fire. Using fluid fire
extinguisher may cause electric shock.
The UPS input power cable is recommended to be less than 2 meters.
Smoking and fire are forbidden within 3 meters around a UPS.
