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 (–) conductors. (Substitute appropri-

ate colors for different colored cables.)

3. Connect the red wire to (+) terminal on TB3 of the plug,

the white wire to COM terminal, and the black wire to the

(–) terminal.

4. The RJ14 CCN connector on TB3 can also be used, but is

only intended for temporary connection (for example, a

laptop computer running Service Tool).

5. Restore power to unit.

IMPORTANT: A shorted CCN bus cable will prevent

some routines from running and may prevent the unit

from starting. If abnormal conditions occur, unplug the

connector. If conditions return to normal, check the

CCN connector and cable. Run new cable if necessary.

A short in one section of the bus can cause problems

with all system elements on the bus.
