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
-- 2 0 _Cto60_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.

(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.
