Primary And Secondary Power Wiring
The AC main connections (TB1) and the battery connections (J4) must be made along the left-
hand side of the main termination board (P/N MPC6-MB or MCP7-MB). Route all high voltage
and non-power limited wiring together and away from power limited wiring. Use the battery
calculation chart to determine battery size.

Status Relays And Auxiliary Power Outputs Wiring
The right side of the main board provides for connection of status relay contacts and auxiliary
power connections (TB5-8). Four relays with dry contacts are provided. These contacts are
programmable to alarm, pre-alarm, trouble and supervisory indications. The relay contacts are
Form C and are rated 1A @ 28VDC resistive.
The right-hand edge of the main termination board (TB9) provides for resettable and non-
resettable auxiliary power connections.
