This example indicates the shielding connection from the PROFIBUS cable to the FE/PE
rail.
Note: An equalization current can flow across a shield connected at both ends because of fluctuations in ground
potential. To prevent this, it is imperative that there is potential equalization between all the attached installation
components and devices.
This example indicates the system components and devices in a system with equipotential
bonding.
Grounding and Shielding for Systems without Equipotential Bonding
Note: Grounding and shielding is to be carried out the same as for systems with equipotential bonding.
If this is not possible because of system or construction specific reasons however, use
distributed ground with a capacitive coupling of high frequency interference signals.
