- 4 - M220 Series Installation Guide
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. 4).
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 ensure that
there is no break in the battery connection wires.
Note: AL300XB2V, AL400XB2V, AL600XB220 and AL1012XB220 (Power Supply Board)
maximum charge current is 0.7A.
AL1024XB2V (Power Supply Board) maximum charge current is 3.6A.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.
