8. To delay AC reporting for 2 hrs., set SW2 to appropriate DIP switch position [AC Delay] (Fig. 1c, pg. 3).
9. To enable or disable Low Output Power Shutdown set SW2 to appropriate DIP switch position [Shutdown]
(Fig. 1c, pg. 3).
10. A short or NO or NC input triggers FACP [Trigger EOL Shutdown] (Fig. 1d, pg. 3).
11. Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
[Trigger EOL Shutdown] (Fig. 1e, pg. 3).
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 (120VAC, Battery).
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.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage
(12VDC @ 13.2 or 24VDC @ 26.4) both at the 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 1.54A.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
