Installation Instructions

AL300ULXD - 3 -
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 Selection chart).
Battery Test: Under normal load conditions, check that the battery is fully charged, check specified voltage both at bat-
tery terminal and at the board terminals marked [– BAT +] to ensure that there is no break in the battery connection wires.
