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 insure that there is no break in the battery
connection wires.
Note: AL300ULXB, AL400ULXB, AL600ULXB and AL1012ULXB (Power Supply Board) maximum charge
current is .7 amp.
AL1024ULXB (Power Supply Board) maximum charge current is 3.6 amp.
Expected battery life is 5 years, however it is recommended to change batteries within 4 years or less if necessary.

CAUTION: De-energize unit prior to servicing. For continued protection
against risk of electric shock and fire hazard replace fuses with the same type
and rating (see marking on the board). Replace fuse cover before energizing.
Do not expose to rain or moisture.
CAUTION: When power supply board is set for 12VDC use only one (1) 12VDC
stand-by battery.
Keep power limited wiring separate from non-power limited. Use minimum .25" spacing.
