Communication Wiring

Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 21,
22 or 23 (page 26). The daisy chain does not need to follow the addressing order. The communication wire should
be 2-wire, 18 gauge shielded cable with drain. Any color can be used. Be sure to match "+" and "-" symbols on
controller terminal blocks to prewired unit control terminal block (see Figures 25 and 26 on pages 28 and 29).
Attach communication wire filters as shown in Figures 21, 22 or 23. Filters go inside the unit or controller box; they
are shown out of unit for identification purposes only. Do not run communication wiring in same conduit as supply
wiring. Route communication wiring and power supply wiring in their own separate conduits.
Wall-Mount Unit
In addition to the "daisy chain" method of connecting the communication wiring shown in Figure 21, the wall-mount
units can also be connected in the manner shown in Figure 22. If connecting wall-units this way, be sure to place
the communication wire filters in the positions shown in Figure 22. See Figure 23 for more information on the
correct placement of the communication wire filters depending on the wiring method used.
