Communications Wiring
For the communications wiring, use 3-wire 20 gauge
shielded cable.
When wiring communication for the th-Tune, the
green connecter plugged into the wall unit PLC
board (with the jumper leads that connect from the
communications terminal block as shown in Figure 17),
will need to be moved from Fieldbus 2, to Fieldbus 1.
