Connect the power cables
See figures A, B, C, D, E, F1, F2 and G. Use symmetrical shielded cable for motor
cabling.
1. Remove the front cover: Loosen the retaining screw with a screwdriver (a) and lift
the cover from the bottom outwards (b).
2. Remove the rubber grommets from the lead-through plate.
3. Cut an adequate hole into the rubber grommet. Slide the grommet onto the cable.
4. Prepare the ends of the input power cable as illustrated in the figure. Note: The
bare shield will be grounded 360 degrees. Mark the pigtail made from the shield
as a PE conductor with yellow-and-green color.
5. Slide the cable through the hole of the bottom plate and attach the grommet to the
hole.
6. Connect the input power cable:
• Ground the shield 360 degrees by tightening the clamp of the power cable
grounding shelf onto the stripped part of the cable. (6a)
• Connect the twisted shield of the cable to the grounding terminal. (6b)
• Connect the additional PE conductor of the cable (6c).
• Connect the phase conductors of the cable to the L1, L2 and L3 terminals.
Tighten the screws to the torque given in the figure. (6d)
7. Repeat steps 3…5 for the motor cable. Two different motor cable types are shown
(7a, 7b).
8. Connect the motor cable. Tighten the screws to the torque given in the figure.
9. Install the grounding shelf for the brake resistor cable.
10. Repeat steps 3…5 for the brake resistor cable (if used). Cut off extra phase
conductors (if any).
11. Connect the resistor cable. Tighten the screws to the torque given in the figure.
12. Install the grounding shelf.
13. Put the unused rubber grommets to the holes in the lead-through plate.
14. Secure the cables outside the unit mechanically.
15. Ground the motor cable shield at the motor end. For minimum radio frequency
interference, ground the motor cable shield 360 degrees at the lead-through of
the motor terminal box.
