The steps outlined on the following pages show how to connect the communication wiring using the daisy chain
method shown in Figure 21 If using the alternate method (as shown in Figure 22), the connections to the controller
and each wall-mount unit will be the same but the filters need to be placed in the positions shown in Figure 23.
1.
Using the field-provided shielded cable, make a small service loop after entering the controller and attach the provided
EMI filter at the intersection of the loop.
2.
Connect one wire to terminal #42 (NEGATIVE), the other wire to terminal #43 (POSITIVE) and the drain wire to
ground terminal #46.
