* Note: Railway installation close to the rails. 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 earthing 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. For more information, see "Safety".
