If a cable with a different color scheme is selected, a similar color code should be adopted for

the entire network.

At each system element, the shields of its communication bus cables must be tied together. If

the communication bus is entirely within one building, the resulting continuous shield must be

connected to ground at only one single point. See Figure 23. If the communication bus cable exits

from one building and enters another, the shields must be connected to ground at the lightening

suppressor in each building where the cable enters or exits the building (one point only).

To connect the 19XL chiller to the network, proceed as follows (Figure 23):

1. Cut power to the PIC control panel.

2. Remove the COMM1 plug from the processor module.

3. Cut a CCN wire and strip the ends of the RED, WHITE, and BLACK conductors.

4. Using a wirenut, connect the drain wires together.

5. Insert and secure the RED wire to Terminal 1 of the COMM1 plug.

6. Insert and secure the WHITE wire to Terminal 2 of the COMM1 plug.

7. Insert and secure the BLACK wire to Terminal 3 of the COMM1 plug.

8. Mount a terminal strip in a convenient location.

9. Connect the opposite ends of each conductor to separate terminals on the terminal strip.

10. Cut another CCN wire and strip the ends of the conductors.
