Electrical installation 65Connecting the power cables Connection diagrama. Two grounding conductors. Use two conductors, if the cross-section of groundingconductor is less than 10 mm2 Cu or 16 mm2 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 fourthconductor or shield is not sufficient for the protective grounding.c. Separate grounding cable (motor side). Use it if the conductivity of the shield is notsufficient for the protective grounding, or there is no symmetrically constructedgrounding conductor in the cable.d. 360-degree grounding of the cable shield. Required for the motor cable and brakeresistor cable, recommended for the input power cable.dcbad
