4. Battery cables are not isolated from AC input. Dangerous voltage may exist between battery
terminal and ground terminal. The battery contains high voltages that may cause injury or death.
Please make sure they are insulated when installing or using the UPS.
5. Conductive objects such as watches, bracelets and rings should not be worn during operation and
maintenance.
6. The UPS installation should be done only by people who have the qualification of high voltage and
AC power operation. Maintenance and repair for power systems must only be done by
professionally trained technicians.
7. Leakage risk! The UPS must be grounded before electrical connection. The ground terminal must
be connected to the ground.
8. It is prohibited to short circuit the positive and negative poles of the battery. The connection of
battery must be tight. It is prohibited to touch the battery’ s two wire connectors or bare wire
terminals, or it may damage the battery and/or endanger life.
9. Prevent the battery electrolyte from overflowing. The metal objects and circuit board inside the
UPS will be corroded by the electrolyte, which will result in equipment damage and short circuiting.
10. Battery should be kept away from fire and all other electrical equipment that could cause sparks,
heat or flame. Avoid danger or unnecessary damage to equipment and personnel.
Contacting high voltage or mains directly onto or near wet objects will cause life risk.
The output of UPS cannot connect with unbalanced load, half-wave rectification load or inductive
load, such as air-conditioner, hair dryer, starter, electric drill, motor, daylight lamp, etc
.
Inappropriate drilling will damage the device inside the cabinet. Metal debris generated by drilling
enters the cabinet will lead to PCB (circuit board) short circuiting.
Life risk!
Cannot connect with unbalanced load, half-wave rectification load or inductive load!
Drilling holes on the cabinet is prohibited!
