Shield connection

Special attention must be given to the shield support for the shielded lines.
Only correct assembly ensures the interference immunity of the system.
A line is shielded in order to weaken the effect of magnetic, electric, and
electromagnetic interference on the line. Interference on cable shielding is routed
to ground through shield rails that are conductively connected with the housing.
To ensure that this interference does not in turn become a source of interference, a
low impedance connection to ground is especially important.
