a. Two grounding conductors. Use two conductors, if the cross-section of grounding
conductor is less than 10 mm

Al (IEC/EN 61800-5-1). For example,
use the cable shield in addition to the fourth conductor.
b. Separate grounding cable (line side). Use it if the conductivity of the fourth
conductor or shield is not sufficient for the protective grounding.
c. Separate grounding cable (motor side). Use it if the conductivity of the shield is not
sufficient for the protective grounding, or there is no symmetrically constructed
grounding conductor in the cable.
d. 360-degree grounding of the cable shield. Required for the motor cable and brake
resistor cable, recommended for the input power cable.
