No current car- Apply capacitative earthing if system parts are not connected to each other in terms of their cur-
rying capacity rent carrying capacity. This prevents the flow of compensation currents through the cable
shields.

The shield connection of the CS31 bus master is internally connected to the
earth terminal.
On the CS31 slave, the shield connection is not connected internally and thus
not earthed. The shield connection can be used to connect the shields of two
cables.
VDE 0160 requires that the system's shield is earthed directly at least once.
