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

The test status (indicated by the second line) can be:
TEST ACTIVATED
TEST ACTIVATED TEST ACTIVATED TEST ACTIVATED = testing
TEST SUCCESSFUL TEST SUCCESSFUL TEST SUCCESSFUL TEST SUCCESSFUL = battery has been tested with positive result
TEST FAILED TEST FAILED TEST FAILED TEST FAILED = the batteries should be replaced
NOT AVAILABLE NOT AVAILABLE NOT AVAILABLE NOT AVAILABLE = battery capacity too low to start the test
If the batteries are dangerously close to being worn out, a low priority alarm 'replace battery' will be generated.
The batteries must be replaced as soon as possible (see section 8.3).
NOTE: If the manual test is started immediately after installation or after a power failure, the UPS may generate
a false 'replace battery' alarm as the batteries have been (partly) discharged during transport/storage or during
the power failure.
