User Manual
 Set Battery capacity after repeated confirmation. Incorrect setting reduces the charging
power.
 When a battery string is shared, the battery capacity of each UPS is the total capacity of
battery strings; when no battery string is shared, the battery capacity of each UPS is the
battery capacity of the single UPS.

A high or low charging power tends to shorten the battery lifespan, or even damages
batteries. If you do not know how to confirm the battery capacity, contact Huawei
technical support.

Number of cells refers to the number of 2 V cells in a single battery string connected to
the UPS. For example, if 36 batteries (150 Ah, 12 V) are connected in series to form a
battery string, and two of such battery strings are connected in parallel and then to the UPS,
set Number of cells to 216 (36 x 6) and Battery capacity to 300 Ah (150 Ah + 150 Ah).
If 192 batteries (300 Ah, 2 V) are connected in series to form a battery string, and two of
such battery strings connected in parallel and then to the UPS, set Number of cells to 192
(192 x 1) and Battery capacity to 600 Ah (300 Ah + 300 Ah). It affects the charge voltage
and discharge time. An incorrect setting will cause a high or low charge voltage, which
greatly shortens the battery lifespan. In addition, the UPS may shut down before the
batteries are fully discharged, which may lead to a data backup fault.
Step 4 If no alarm is displayed on the Monitoring screen, skip this step; if an alarm is displayed,
clear the alarm.
