Communication Wiring
Connect the communication wiring from the wall-mount units to the controller in the manner shown in Figures 17,
18 or 19 (page 30). 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 21 and 22 on pages 32 and 33).
Attach communication wire filters as shown in Figures 17, 18 or 19. 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 17, the wall-mount
units can also be connected in the manner shown in Figure 18. If connecting wall-units this way, be sure to place
the communication wire filters in the positions shown in Figure 18. See Figure 19 on page 30 for more information
on the correct placement of the communication wire filters depending on the wiring method used.
