3.2 Connections on the CP fieldbus node

CP fieldbus nodes have the following connections:

– fieldbus connection (design depends on type)

– operating voltage connection

– earth/ground connection

– CP connections

Earth/ground connection
Fieldbus connection (design depends on type used, see node manual)
Operating voltage connection
CP connections for up to 4 strings (0...3)
