6. MAINTENANCE

Only minimum maintenance is required for this series of UPS. The battery is sealed lead acid maintenance

free. It only needs to be kept charging to obtain the expected life. Whether it is started or not, the UPS would

charge batteries once it is connected to mains and provide protection for over-charging and deep discharg-

ing.

6.1. BATTERY MAINTENANCE

1. It is recommended that the batteries are manually charged or discharged.

2. once every three or four months if UPS has not been used for a long time or the power is long-term un-

interruptible. The battery will be fully discharge to low-voltage protection shutdown. Then it needs to be

fully charged once.

3. In high temperature area, batteries should be manually charged and discharged once every two months.

The process is the same as that said above.

4. Under normal circumstances of using, the battery working life is three to ﬁve years. If you ﬁnd that the

battery do not act well such as obviously shortening of backup time, too much imbalance on battery

voltage so on, the battery should be replaced as soon as possible, which must be performed by qualiﬁed

personnel.

5. When replace battery, it is recommended to change battery all together instead of changing separately.

ment such as ﬁnger ring, watch and so on.
