Connecting the grounding conductor

The machine's grounding conductor cross-section must comply with EN / IEC 60034-1.
Please also observe installation regulations such as those specified in EN / IEC 60204-1.
Basically, there are two ways of connecting a grounding conductor to the machine.
• Internal grounding with a connection in terminal box at the location intended for this
purpose and marked accordingly.
• External grounding with connection at the stator housing at the locations intended for
this purpose and marked accordingly.
