CAUTION:
The auxiliary contacts inside the EPO switch assembly must close when the switch is
pressed. This contact closure energizes the relay inside the power distribution unit,
causing the connection to the battery holdover assembly to open.
‘‘External Alarm Cable Connection’’ on page 92
shows the cabling from the auxiliary
contacts inside the EPO switch assembly and how they connect to the internal relay.
3 Connect the RPO wires to the auxiliary contacts on the EPO switch. See ‘‘External
Alarm Cable Connection’’ on page 92.
NOTE:
The EPO switch and the auxiliary contacts for the RPO connection are customer-supplied.
