5.4.1 Battery Test, general
Automatic test: Every 500 operating hours the UPS conducts automatic battery tests to ensure that the
batteries and the wiring are able to support power failures. The tests do not cause any interruption in the
functioning of the unit.
Manual test: A manual battery test can be activated
- either through an interface kit, via the RS232 or SNMP Interface Port (please refer to the manual of
your interface package), or
- via the front panel: see below

a false 'replace battery' alarm as the batteries have been (partly) discharged during transport/storage or during
the power failure.
