When connecting the CCN communication bus to a system element, a color code system for
the entire network is recommended to simplify installation and checkout. The following color
code is recommended:
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).
