7 Troubleshooting
● If the UPS is faulty, alarm information is displayed on the LCD. The UPS can be
powered on only after critical alarms are handled. Failing to do so may escalate
faults or damage the equipment.
● Do not clear alarms by reinstalling modules.
● Remove a faulty module after
conrming that it needs to be replaced. After
removing the module, do not insert it into the UPS again.
● After a UPS is troubleshooted and started, if the LCD continues displaying
alarm information, choose System Info. > Alarms > Clear Faults to clear the
alarm and then start the inverter.
● To restore battery discharge after batteries reach EOD, use either of the
following methods: 1. Switch to another battery string. Ensure that each battery
has a voltage greater than the EOD voltage and 11.3 V/cell. 2. Restore the
mains power supply to start the inverter. Turn on the battery switch and charge
batteries until each battery has a voltage greater than the EOD voltage and
11.3 V/cell.
If any unmentioned faults occur, see the alarm list or contact Huawei technical
support.
