Shield HF-connected
NOTE! Railway installation close to the rails.
For a cable located inside 3 m boundary and connected to this
port, the use of shielded cable is recommended, this is to mini-
mise the risk of interference. The cable shield should be prop-
erly connected (360°) to an earthing point within 1 m from
this port. This earthing point should have a low impedance con-
nection 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.
