8.3.3.3 UL-compliant connection of the grounding conductor
Note that UL-compliant operation requires just a single grounding conductor.
The grounding at terminal X10 of the SC6 drive controller must not be used for protective grounding. The housing for the
drive controllers must be connected to the protective grounding using the M6 ground bolt (4.0 Nm, 35Lb.inch).
You will need an open-ended wrench or external hex key with a width across flats of 10mm.
