6 Routine Maintenance
Troubleshooting
Identify the cause of an alarm
based on the alarm
information.
If the battery appearance is
abnormal, contact Huawei
technical support.
1. Identify the cause of an
abnormal battery operating
temperature.
2. If the fault persists, contact
Huawei technical support.
1. If the voltage drop between
the battery string output
terminals and the battery
input terminals at the UPS
side is greater than 1% of
the battery string voltage,
check whether the cable
between the battery string
and the UPS is excessively
long, or the cable diameter
is excessively small.
2. Check whether the
equalized charging voltage
and float charging voltage
are correctly set for the
UPS.
3. If the fault persists, contact
Huawei technical support.
