● The material of the protective grounding conductor must be the same as the
material of the power cable. If this is not the case, the specific resistance of the
protective grounding conductor must not be higher than the specific resistance
of the power cables. The relevant diameter of the power cables is the diameter
of the line supply cable, and not the diameter of the motor cables.
● In the case of power cables up to 35 mm
2
, the ground cable must have a cross
section of at least 10 mm
2
(16 mm² Al).
● For power cables with a diameter of more than 35 mm
2
, the protective
grounding conductor must have at least half of the size of the cross-section of
the power cable.
● If possible, use at least 16 mm
2
for the copper equipotential-bonding cable.

No shielding dimensions are indicated for the input power cables because they
are generally unshielded cables.
