●
Before switching on and before commissioning, ground or connect the com-
ponents of the electric drive and control system to the equipment grounding
conductor at the grounding points.
●
Connect the equipment grounding conductor of the components of the elec-
tric drive and control system permanently to the main power supply at all
times. The leakage current is greater than 3.5 mA.
●
Establish an equipment grounding connection with a minimum cross section
according to the table below. With an outer conductor cross section smaller
than 10 mm 2 (8 AWG), the alternative connection of two equipment ground-
ing conductors is allowed, each having the same cross section as the outer
conductors.
