You provide the appropriate power cable to connect a processor with a
power supply (1771-P3, -P4, -P5 power supplies) to its terminal strip. A
processor without a power supply receives its power from the backplane of
the I/O chassis.

To connect the wires to the processor power plug or power supply terminal
strip, do the following:

Connecting the Processor

1. Strip 3/32 inch insulation from the end of the wire.

2. Insert screwdriver (tip should be no greater than 3/32 inch wide) into

the square opening.

3. Press down with the screwdriver. Figure 4.20 shows a top view of

the power plug.

4. Insert the wire into the round opening on the front of the plug.

5. Remove screwdriver.
