To discharge the EMC interferences, connect the FE connection (8) on the bus coupler via
a low-impedance line to functional earth.
The line cross-section must be selected according to the application.
An adequate potential equalization line is needed between the devices to avoid compensating
currents from flowing over the shield of the bus coupler.
