Input power cable 3
Two protective earth (ground) conductors. Drive safety standard IEC/EN 61800-5-1
requires two PE conductors for a fixed connection, if the cross-section of grounding
conductor is less than 10 mm2 Cu or 16 mm2 Al. For example, you can use the cable
shield in addition to the fourth conductor. 4
Separate PE cable (line side). Use a separate grounding cable or a cable with a separate
PE conductor for the line side, if the conductivity of the fourth conductor or shield
does not meet the requirements for the PE conductor. 5
Motor cable
Note: ABB recommends to use a symmetrical shielded cable (VFD cable) as the motor
cable. 6
Separate PE cable (motor side). Use a separate grounding cable for the motor side, if
the conductivity of the shield is not sufficient, or if there is no symmetrically constructed
PE conductor in the cable. 7
360-degree grounding of the cable shield. Required for the motor cable and brake
resistor cable (if used, for frame R2...R4 only), recommended for the input power cable. 8
Brake resistor (optional, for frame R2...R4 only). 9
