Configuring battery settings

Automatic battery test
Automatic battery tests are done every week in constant charging mode and at each cycle in ABM mode.
The tests frequency can be modified.
During the test, the UPS transfers to Battery mode and discharges the batteries for 25 seconds under load.
Battery mode is not displayed and battery low alarm does not activate during a battery test.
The battery test may be cancelled due to bad conditions, or failed.
Low battery warning
During discharge, the low battery alarm is activated if the battery capacity goes below 20%.
This threshold can be modified.
External battery setting
The number of Extended Battery Module is automatically detected, or can be set manually in number of
EBM or in Ah.
Deep discharge protection
This setting is recommended to avoid damaging the battery. Warranty is void if deep discharge protection is
disabled.
