AL1024NK8QP Series Installation Guide
- 5 -
Wiring:
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).
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 AL1024ULXB2: 24VDC nominal rated @ 10A max.
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified voltage
(24VDC @ 26.4) both at 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 discharges is 3.6A.
Note:
Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
