10.1 Connection of Shielding
To avoid elektromagnetic influences it is necessary to connect cable shields at both ends.
This includes shielding from control housing to sensors, from control housing to
potentiometers, from control housing to actuator and from control housing to accessory
units. If there is a potential difference between the control housing and any of these other
componets, to avoid currents via the shielding it is necessary to run a separate wire from
the control housing to each of these components.

At cable ends without plugs (e.g. terminal strip or pins) the shielding must be connected at
the housing near the contacts.
