GENERAL SYSTEM | TEST START | the test will start soon |

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
5.4.2Quick Battery Test
From the standard menu first enter the service menu (press the 'down' and 'Enter/Reset' keys simultaneously, then press the 'down' key until the following screen appears:
QUICK BATTERY
TEST PRESS ENTER
The ‘Enter/Reset’ key confirms the selection, and the screen shows:
QUICK BATTERY
TEST START
The test status (indicated by the second line) can be:
= testing
= battery has been tested with positive result
= the batteries should be replaced
= 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.
