NOTE: The periodical self-test should satisfy the conditions of battery float charge at least 5 hours, and generator not
connected, while the manual maintenance self-test just satisfies the conditions of battery fully charged.
How to do a test
1. Manual maintenance self-test: Via the Touchscreen.
2. Periodical self-test: A self-test period can be configured via the Vertiv setting software. The range of battery
self-test period is 30 days to 360 days. The default is 60 days.
Self-test startup conditions
1. System load rate is within 0 to 100% (manual maintenance) or 20% to 100% (periodical self-test), stable output.
2. Battery in fully charged state, battery float charge at least 5 hours and generator not connected.
3. Current system is in float charge state.
self-test exit conditions
1. Confirm that the system is not in self-test state for at least 10 seconds and battery mode or rectifier is closed.
The system shifts to battery supply state.
2. During the self-test, the system will shift to float charge state if the load fluctuation, UPS module overload or no
battery occurs.
3. During the self-test, if the battery voltage is lower than the calculated pre-alarm voltage, or the battery discharge
exceeds the protection time, then the system will shift to float charge state.
4. The user can manually stop the maintenance test via the Touchscreen.
5. During the manual maintenance self-test, when the load rate ranges from 0 to 20%, the system will shift to float
charge state after the battery discharge for 5 mins.
NOTE: After the self-test is successful, the system will fully clear the self-test interval counter. If the self-test fails
this time, then exits the system; when self-test conditions are satisfied again, enters self-test once more.
