WARNING:

Turn off AC power to the panel and

each motor control circuit at the circuit

breaker.

1. Verify the AC power from the circuit breaker

panel to the RCU is off.

2. Unplug the power supply from the outlet.

CAUTION:

Before removing the wires, use a

voltmeter to ensure no power is running

through the DO wiring.

3. Disconnect one set of wires associated with a

point from the termination strip.

4. Write the MBC/MEC address from the layout

sheet on the tag, and wrap the tag around the

bundle of wires associated with the point.

Tag the wires as close to the point of entry into

the cabinet as possible.

5. Write the wire designation (NO, NC, COM, SIG,

GND) from the picket of each wire on the wire

tag. Wrap the tag around each wire.

NOTE: Do not disconnect another set of wires until

you have properly tagged and marked the

wires you just removed.

Continue with steps 3 through 5 until all the wires

are removed from the termination strips and tagged.
