Earth connection

The internal PE connection of the lower section is conductively connected with the housing.
However, from the point of view of screening, connection to the outside of the housing is
preferable.
The external earth connection of the lower section is located lower left, adjacent to the round
connectors. The PE conductor is screwed to the housing with a crimp connector. In order to
guarantee safe earthing, the serrated washer must be mounted between the crimp connector
and the housing.

Ring termination

A characteristic of the INTERBUS system is its physical ring structure. Each connected device
lies in the bus between two other stations. If this is not the case, for example, at the end of a
branch with a bus terminal, then the ring line must be closed.
The ring line in the lower section U-P6-B5-V is automatically closed. If the network of the
installation remote bus is extended at the outgoing connection point using a suitable cable, the
0 V potential is laid to the "RBST" input, so that the ring line is automatically opened for the
following devices.
