Clamp the screening of the field bus cable under the cable
clip of the Festo sub-D plug (see diagram).
Please note
The cable clip in the Festo sub-D plug is connected inter-
nally only capacitively with the metallic housing of the
sub-D plug.
This is to prevent equalizing currents from flowing through
the screening of the field bus cable (see diagram).
