signalling and telecommunications apparatus and located close
to rails*

*
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 functional
earth. Refer also to "Safety" section.
