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
(Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the
battery terminal and at the board terminals marked [- BAT +] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharge is 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
