Guidelines for grounding and chassis grounding concept
When it ships, the CP has a jumper inserted between the M and functional earth
terminals. If you want to ground the reference potential, do not remove the jumper
between the M and functional
earth terminals.
Note the information in the SIMATIC S7 installation guidelines for grounding and chassis
grounding, see
/2/ (Page 48)
In this document
