Fig. 29 Ð Optional VFD Ð Wiring Connections

Carrier Comfort Network Interface Ð The 48/50MP units can be connected to the CCN if desired. The communication bus wiring is supplied and installed in the ®eld. It consists of shielded, 3-conductor cable with drain wire.

The system elements are connected to the communication bus in a daisy chain arrangement. The positive pin of each system element communication connector must be wired to the positive pins of the system element on either side of it, the negative pins must be wired to the negative pins, and the signal pins must be wired to signal ground pins. Wiring con- nections for CCN should be made at the 4-pin plug (COMM) located at the bottom right side of the fuse bracket in the main control box. Consult CCN Contractor's Manual for fur- ther information.

NOTE: Conductors and drain wire must be 20 AWG mini- mum stranded, tinned copper. Individual conductors must be insulated with PVC, PVC/nylon, vinyl, Te¯on, or poly- ethylene. An aluminum/polyester 100% foil shield and an

outer jacket of PVC, PVC/nylon, chrome vinyl, or Te¯on with a minimum operating temperature range of 220 C to 60 C is required. See Table 7 for cables that meet the requirements.
