Battery maintenance
The condition of the batteries is crucial to correct operation of the UPS. The UPS units are
provided with the automatic battery test ABM, which continuously controls the condition of
the battery bank. When the capacity of the battery bank has decreased remarkable, the
SERVICE LED starts blinking and audible alarm is activated.
In addition to the automatic battery test it is recommended that a battery discharge test is done
once or twice per year. This test is recommended to be done together with the preventive
maintenance by manufacturer service personnel. In the parallel for redundancy system it is
possible to do a complete discharge test for one UPS without risking the load. The other UPS
will stay in online mode and supply the full load in case of failure in the tested UPS.
Scrapping the UPS
Before scrapping UPS or its battery cabinet, battery bank and lithium battery on the logic
board must be removed. Due to high energy and high voltage, removal of batteries is
allowed only for authorised service personnel. Local requirements must be followed in
battery recycling or discard.
