8.2 Replacement and Disposal of Batteries
1) Before disposing of batteries, remove conductive jewelry such as
necklace, wrist watches and rings.
2) If it is necessary to replace any connection cables, please
purchase the original materials from the authorized distributors or
service centers, so as to avoid overheat or spark resulting in fire
due to insufficient capacity.
3) Do not dispose of batteries or battery packs in a fire, they may
explode.
4) Do not open or mutilate batteries, released electrolyte is highly
poisonous and harmful to the skin and eyes.
5) Do not short the positive and negative of the battery electrode,
otherwise, it may result in electric shock or fire.
6) Make sure that there is no voltage before touching the batteries.
The battery circuit is not isolated from the input potential circuit.
There may be hazardous voltage between the battery terminals
and the ground.
7) Even though the input breaker is disconnected, the components
inside the UPS are still connected with the batteries, and there are
potential hazardous voltages. Therefore, before any maintenance
and repairs work is carried out, switch off the breaker of the
battery pack or disconnect the jumper wire of connecting between
the batteries.
8) Batteries contain hazardous voltage and current. Battery
maintenance such as the battery replacement must be carried out
by qualified personnel who are knowledgeable about batteries. No
other persons should handle the batteries.
