6.4 Battery Test Procedures
The battery test function is disabled by default. If you need this function, please contact the customer service engineer of
Vertiv.
The battery self-test includes periodical self-test and manual maintenance self-test. When the load factor is 0 to 20%, the
system only supports manual maintenance self-test; when the load factor is 20% to 100%, the system supports periodical
self-test and manual maintenance self-test. The battery discharges 20% of total battery energy.
Periodical self-test is to test the battery activity. The periodical self-test is regular, and the self-test period can be
configured via the Vertiv setting software. During the periodical self-test, if the battery maintenance requirement is met, the
system will generate audible/visual alarm and corresponding records. The periodical self-test does not update the battery
curve table.
The mode of the manual maintenance self-test is similar to that of the periodical self-test, except for the maintenance self-
test mode is started manually, and this operation is valid only one time, that is the system will not be automatically start up
the self-test once you exit. During the maintenance self-test, if the battery maintenance requirement is satisfied, the system
will generate audible/visual alarm and corresponding records. The maintenance self-test does not update the battery curve
table.
N O T E: T h e perio dical self-test sh o u ld satisfy th e co n ditio n s o f battery flo at ch arge at least 5 h , an d
gen erato r n o t co n n ected, wh ile th e m an u al m ain ten an ce self-test ju st satisfies th e co n ditio n s o f
battery fu lly ch arged.
Method
1. Manual maintenance self-test: via the TOUCH SCREEN.
2. Periodical self-test: self-test period can be configured via the Vertiv setting software. The range of battery self-
test period is 30 days to 360 days (default: 60 days).
Self-test startup conditions
1. System load rate is within 20% to 100%, stable output.
2. Battery in fully charged state, battery float charge at least 5 h, 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 at least 10 seconds, and satisfies the following conditions: in
battery mode or rectifier is closed, and then the system will shift 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 TOUCH SCREEN.
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 min.
N O T E: A fter th e self-test is su ccessfu l, th e system will fu lly clear th e self-test in terval co u n ter. If th e
self-test fails th is tim e, th en exits th e system ; wh en self-test co n ditio n s are satisfied again , en ters self-
test o n ce m o re.
