Grounding Function
The grounding function increases the resistance against electro-magnetic
interferences. Some components in the I/O system have a carrier rail contact that
dissipates electro-magnetic interferences to the carrier rail.

connectors of the supply modules enable optional
connection of a field-side functional ground. This potential is made available to
the I/O module arranged on the right through the spring-loaded contact of the
three power contacts. Some I/O modules are equipped with a knife-edge contact
that taps this potential. This forms a potential group with regard to functional
ground with the I/O module arranged on the left.
