NO TICE
The UPS is working in normal mode; float charging or hibernation has lasted
for 2 hours after the SOC reaches 100%; and the load ratio fluctuation 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.
When shallow discharge tests are complete, the system records data of the
latest five tests. For details about how to view the test data, see
Test Data.
The shallow discharge test automatically stops in any of the following cases:
a. The battery discharge capacity reaches the specified value (10%–50%,
20% by default).
b. The battery discharge voltage reaches the warning threshold (calculated
in real time by battery management).
