Fig. 84 — CCN Connections

Carrier Comfort Network® (CCN) Interface —

The 48P Series units can be connected to the CCN system if desired. The communication bus wiring is supplied and installed in the field. It consists of shielded, 3-conductor cable with shield 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 common pins. Wiring connections for the CCN system should be made at the terminal block using the screw terminals. The board also contains an RJ14 CCN plug that can be used to connect a field service computer. There is also another RJ14 LEN (Local Equipment Network) connec- tion that is used to download software or connect a Naviga- tor™ device.

NOTE: Conductors and drain wire must be 20 AWG minimum stranded, tinned copper. Individual conductors must be insu- lated 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 –4 to 140 F (–20 C to 60 C) is required. See Table 28 for cables that meet the requirements.

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.

The following color code is recommended:

SIGNAL

CCN BUS CONDUCTOR

COMM1 PLUG

TYPE

INSULATION COLOR

PIN NO.

+

RED

1

COMMON

WHITE

2

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 its communication bus cables must be tied together. If the communication bus is entirely within one building, the resulting continuous field must be connected to a ground at one point only. If the commu- nication bus cable exits from one building and enters another, 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 (Fig. 84):

1.Turn off power to the control box.

2.Cut the CCN wire and strip the ends of the red (+), white (common) and black (–) conductors. (If a different net- work color scheme is used, substitute appropriate colors.)

3.Wire the CCN to the screw terminals on the COMM board as follows (Fig. 84):

a.Secure the red (+) wire to CCN screw terminal + on the COMM board.

b.Secure the white (common) wire to CCN screw terminal C on the COMM board.
