3.Connect the other end of the communication bus cable to the terminal block labeled CCN in the zone control- ler of the first air terminal. Following the color code in Table 3, connect the Red (+) wire to Terminal 1. Connect the White (ground) wire to Terminal 2. Con- nect the Black (–) wire to Terminal 3.

4.Connect additional zone controllers in a daisy chain fashion, following the color coded wiring scheme in Table 3. Refer to Fig. 25.

NOTE: The communication bus drain wires (shield) must be tied together at each zone controller. If the communica- tion bus is entirely within one building, the resulting contin- uous shield must be connected to ground at only one single point. If the communication bus cable exits from one build- ing and enters another building, connect the shields to ground at a lightning suppressor in each building where the cable enters or exits (one point only).
