Maintenance; Power Supply Board Output Voltage Settings - Altronix MAXIMAL FIT MaxFit E Series Installation Manual

Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, Battery).
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test:
Battery Test:
Note: AL400ULXB2, AL600ULXB and AL1012ULXB Power Supply Board maximum charge current is 0.7A.
AL1024ULXB2 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.

Under normal load conditions the DC output voltage should be checked
for proper voltage level
(Power Supply Board Stand-by Battery Specifications, pg. 7).
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.
