NOTE!
Settings of the S2 switch:
S2.1 = ON and S2.2 = ON: RS-485 is ON.

The factory default for the S2.1 and S2.2 switches are OFF.
Other combinations of switch S2 are not allowed.
Follow instructions below for the proper installation of the control wiring:
1. Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum tightening torque: 0.50 N.m (4.50 lbf.in).
3. Use shielded cables for the connections in XC1 and run the cables separated from the remaining
circuits (power, 110 V / 220 Vac control, etc.), according to
22. If control wiring must cross other cables (power cables for instance), make it cross
perpendicular to the wiring and provide a minimum separation of 5 cm (1.9 in) at the crossing
point.
