5.1.6 Shielding and grounding
Optimal electromagnetic compatibility (EMC) of the fieldbus system can be guaranteed only 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.
1. To ensure optimal EMC protection, connect the shield to the reference ground as often
as possible.
