Disconnecting device 1
Input power cable 2
Two protective earth (PE) conductors, eg, fourth conductor and cable shield. According to drive safety
standard IEC/EN 61800-5-1: 3
• there must be two separate PE conductors, or one min. 10 mm
2
(8 AWG) Cu conductor
• minimum size for individual PE conductor is 2.5 mm
2
(14 AWG) Cu.
Separate PE cable (line side). Use it if the conductivity of the fourth conductor or shield is not sufficient
for the protective grounding. 4
Motor cable 5
Separate PE cable (motor side). Use it if the conductivity of the shield is not sufficient for the protective
earth conductor, or there is no symmetrically constructed grounding conductor in the cable. 6
360-degree grounding of the cable shield. Required for the motor cable and brake resistor cable, recom-
mended for the input power cable. 7
Brake resistor cable (optional) 8
