7.1.5 Shielding and grounding
PROFIBUS PA
Optimum electromagnetic compatibility (EMC) of the fieldbus system can only be
guaranteed if the system components and, in particular, the lines are shielded and the
shield forms as complete a cover as possible. A shield coverage of 90% is ideal.
• To ensure an optimum EMC protective effect, connect the shield as often as possible to
the reference ground.
• For reasons of explosion protection, you should refrain from grounding however.
To comply with both requirements, the fieldbus system allows three different types of
shielding:
• Shielding at both ends.
• Shielding at one end on the feed side with capacitance termination at the field device.
• Shielding at one end on the feed side.
Experience shows that the best results with regard to EMC are achieved in most cases in
installations with one-sided shielding on the feed side (without capacitance termination at
the field device). Appropriate measures with regard to input wiring must be taken to allow
unrestricted operation when EMC interference is present. These measures have been
