Disconnecting device1
Input power cable2
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 PE conductor with a minimum cross-
sectional area of 10 mm
2
Cu
• the minimum cross-sectional area of an individual PE conductor is 2.5 mm
2
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 cable5
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, recommended for the input power cable.
