Every time the AC mains is introduced into UPS, the UPS
automatically tests the battery, provided that the mains voltage is
within tolerances and the load ranges between 33~100% rated load.
When in Normal mode, provided that the mains input is normal, no
overload exists, and the battery voltage is no lower than 36V
(UH11-0010(L) UPS) or 120V (UH11-0020/0030(L) UPS) or 96V
(UH11-0020(L)B UPS), manual test can be conducted by pressing
button on the front panel: press and hold the ON/SILENCE button
for 4 seconds (a beep is heard 3 times) and then relieve it. 3
seconds later, the battery test begins, the battery indicator shines,
and the buzzer beeps as in Battery mode. After battery test, the
buzzer stops beeping, the battery indicator goes off, and the
displays of the panel indicators restore to the state prior to test.
When battery fault is detected (no battery, faulty battery, or battery
reverse connection) during test, the fault indicator shines, and the
battery indicator flashes.
Notice
After battery test, the battery state information will be refreshed. In
the event battery fault that the battery is not fully charged is detected
during test, user may retest the battery after fully charging it to
confirm that the fault is removed.
