Table 8 – Color Code Recommendations

50TC

NOTE: Conductors and drain wire must be at least 20 AWG, stranded, and tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An aluminum/polyester 100% foil shield and an outer jacket of PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum operating temperature range of -20_C to 60_C (-4_F to 140_F) is required. Do not run communication wire in the same conduit as or next to any AC voltage wiring.

The communication bus shields must be tied together at each system element. If the communication bus is entirely within one building, the resulting continuous shield must be connected to ground at only one single point. If the communication bus cable exits from one building and enters another building, the shields must be connected to the grounds at a lightning suppressor in each building (one point only).

Connecting CCN bus:

NOTE: When connecting the communication bus cable, a color code system for the entire network is recommended to simplify installation and checkout. See Table 8 for the recommended color code.

Connect the CCN (+) lead (typically RED) to the unit’s TB1-12 terminal. Connect the CCN (ground) lead (typically WHT) to the unit’s TB1-14 terminal. Connect the CCN (-) lead (typically BLK) to the unit’s TB1-16 terminal. See Fig. 44.
