J2 connector and to a 24 Vdc power source; when using a 115/230 Vac
power source, connect a 110 Vac power cable to the PRC-PS J3 connector
and a 115/230 Vac power source.
3. Power on the PRC-PS and observe the indicator lights:
• Fault indicator light, illuminates if the battery is not connected
properly or is shorted.
• Charging indicator light, illuminates during normal charge cycle
• Ready indicator light, illuminates when the battery is fully charged.
4. Leave the PRC1077 powered off unless it needs to be operated while
being recharged.
