Additional information about the ring feeding
In order to increase the system security, a ring feeding of the earth potential is
recommended. Thus, if a bus module comes loose from a composite during
servicing, then the protective conductor connection is still guaranteed for all
connected field devices. With the ring feeding, protective grounding is connected
at the beginning and the end of a potential group.
Please refer for further information to chapter „Grounding “> “Grounding
Protection”, Ring Feeding.
