Caution:Considering electromagnetic interference, one must apply shielded wires to connect RS-485 interface signals. The shield must be con-nected to the earth terminal in a single point. The supply should be connected to the earth terminal in a single point. The supply should be connected by a two-wire cable, with an appropriate diameter of wires assuring its protection by means of an installation cut-out.
