IMPORTANT: When connecting the CCN communica- tion bus to a system element, use a color coding system for the entire network to simplify installation and checkout. See Table 10.
Table 10 — Color Code Recommendations
SIGNAL | CCN BUS CONDUCTOR | CCN PLUG |
TYPE | INSULATION COLOR | PIN NO. |
Positive (+) | RED | 1 |
Ground | WHITE | 2 |
Negative | BLACK | 3 |
NOTE: 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 the communication bus cables must be tied together. If the communication bus is entirely within one building, the resulting continuous shield must be connected to a ground at one point only. If the com- munication bus cable exits from one building and enters anoth- er, the shields must be connected to grounds at the lightning suppressor in each building where the cable enters or exits the building (one point per building only).
To connect the unit to the network:
1.Turn off power to the control box.
2.Cut the CCN wire and strip the ends of the red (+), white (ground), and black
3.Remove the
