Disconnect all electric power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure that power cannot be
inadvertently energized. Failure to disconnect power before servicing could
result in death or serious injury.

Connect WCI Wires to Controller
Note: It is normal for the
Repeater DIAG LED to flash.
Note: Field-supplied.
Connect both 2-connector screw
terminal blocks to either of the
IMC terminals on the PM014.
Power ON Device
Note: If all devices
cannot be powered on at
the same time, the best
practice is to power them
on in the following order:
1. All WCIs
2. All unit controllers:
UC210, UC400,
UC600, BCI-I, BCI-R
3. All Tracer SCs
4. All WCSs
