    MILPOWER SOURCE 110BA1UM, REV(B) Operation, Controls and Indicators (ref. Figures 4 and 5) Turning the UPS ON and OFF In order to turn the UPS ON (after an electrical connection is made), turn ON the Input ON/OFF switch (4), the Master ON/OFF switch (5) and the remote ON/OFF switch. (The order is not important).

  • Page 13: Input Ac Failure

    MILPOWER SOURCE 110BA1UM, REV(B) 6.2.3 Input AC Failure When the input AC voltage is below the minimum required for proper operation, the UPS runs on battery power. During this condition the red Input Fail LED (6) is on, the yellow On Battery Warning LED (11) blinks, and five seconds after input power loss an audible alarm starts beeping once every five seconds.

  • Page 14: Battery Test

    Charge-Discharge Cycles Temperature The battery used in the M110BA-1 is sealed and does not “dry up” or lose gasses, but its end of service life is brought about by the gradual corrosion of the electrodes. This process is accelerated by high operating temperatures. Every 10°C rise above 20°C will reduce the battery service life by half.

  • Page 15: Replacing The Battery Pack

    Replacing the Battery Pack For ease of use, the battery of the M110BA-1 is packaged within a Removable Battery Pack (MPS P/N M357380) that may be ordered separately. During storage, the Battery Pack may be removed and stored separately in a cooled ambient.
