Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level
(Output Voltage and Stand-by Specification Charts, pg. 5).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at the battery
terminals and at the board terminals marked [– BAT +] to insure that there is no break in the battery connection wires.
