To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m
boundary to the rails and connected to this port.
The cable shield should be properly connected (360°) to an earthing point within 1 m from this port. This earth-
ing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or
similar, where the unit is built-in. This conductive enclosure should be connected to the earthing system of an
installation and may be directly connected to the protective earth.
