4.5.2 Shield connection
Special attention must be given to the shield strip for shielded lines. The
interference resistance of the system can only be guaranteed if the properly
constructed.
A cable is shielded to decrease the affects of magnetic, electrical and
electromagnetic interference on this line. Interference on cable shielding is routed
to ground through shielding rails that are conductively connected with the housing.
To ensure that this interference stream does not become a source of interference,
a low impedance connection to ground is especially important.
Use only lines with mesh-shielding. Shielding should provide at least 80%
coverage.
For fastening the meshed shielding, use only metal cable clamps. The clamps
must cover as much shielding as possible and ensure a good contact.
