Huawei UPS5000-E-30 kVA - Capacity Test

Manual Shallow Discharge Test
NO TICE
Before the test, ensure that:
● The UPS is working in normal mode, the SOC is greater than 95%, the lowest
cell voltage is greater than or equal to 3.35 V/cell, and the load rate
uctuation
is less than 10%.
● The UPS has generated no battery overtemperature, overvoltage, or overcurrent
alarm. No generator is connected to the UPS.
● The mains, batteries, charger, and discharger are normal. No overload alarm is
generated.
● The SmartLi has generated no alarms related to lithium batteries.
1. On the home screen of the UPS LCD, choose System Info > Maintenance >
Battery Maint.
2. Tap Start next to Shallow Dis. Test to start a shallow discharge test.

NO TE
When the battery test is completed normally, the test data is used as common test
data. Record the data obtained from the latest ve tests.
The shallow discharge test automatically stops in any of the following cases:
● The battery discharge capacity reaches the specied value (10%–50%, 20% by
default).
● The discharge voltage reaches the warning threshold (calculated in real time).
● The load ratio
uctuation exceeds 10%.
● A fault alarm is generated.
