20 EN – R6…R9 Quick installation guide
Connect the power cables
See figure C on page 157. Use symmetrical shielded cable for motor cabling. If the
cable shield is the sole PE conductor for drive or motor, make sure that is has
sufficient conductivity for the PE.
1. Attach the residual voltage warning sticker in the local language next to the
control board.
2. Remove the side plates of the cable entry box: Loosen the retaining screws and
slide the walls out.
3. Remove the shroud on the power cable terminals by releasing the clips with a
screwdriver and pulling the shroud out.
4. Knock out holes for the cables to be installed.
5. Cut an adequate hole into the rubber grommet. Slide the grommet onto the cable.
6. Prepare the ends of the input power cable and motor 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.
7. Slide the cables through the holes of the bottom plate and attach the grommets to
the holes (the motor cable to the right and the input power cable to the left).
8. Connect the motor cable:
• Ground the shield 360 degrees under the grounding clamp (8a).
• Connect the twisted shield of the cable to the grounding terminal (8b).
• Connect the phase conductors of the cable to terminals T1/U, T2/V and T3/W.
Tighten the screws to the torque given in the figure (8c). Note: Phase
conductors (R8, R9) are detachable.
9. Connect the input power cable as in step 8. Use terminals L1, L2 and L3.
10. R8…R9:
If you install parallel, install the second grounding shelf for the parallel
power cables. Repeat steps 5...9.
11. Install the grounding shelf for the control cables.
12. Reinstall the shroud on the power terminals.
13. Secure the cables outside the unit mechanically.
14. 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.
