Precautions
Human Safety
1. Before performing any operation, carefully read this document.
2. To prevent electric shocks, get tools insulated and wear insulated gloves when connecting cables.
3. To prevent personal injury, wear protective shoes when moving batteries.
4. In case of fire, use a dry power fire extinguisher to put out the fire. Using a fluid fire extinguisher may cause
electric shocks.
5. Do not touch uninsulated battery terminals. Otherwise, electric shocks may occur.
6. Using incorrect battery models may cause explosion. Dispose of used batteries by following the instructions.
7. Cut off power supply and remove all metal objects such as watches and rings before maintenance.
8. When connecting cables, first connect cables to the cable distribution box and the UPS, and then insert the
cables to terminals on the battery cabinet. When removing cables, first disconnect the cables from the
battery cabinet, and then cables from the cable distribution box and the UPS.
9. Do not move a battery pack by holding its mounting brackets, front panel, or fuse cover. Because the
battery pack is heavy, several persons are required to move it in compliance with safety regulations.
