30 EN – R1…R4 Quick installation guide
Connect the power cables
See figures C1 (page 431), C2, D, E1, E2, F, G1, G2 and R1…R4 Figures H (page
433).
1. Remove the rubber grommets from the cable entry.
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.
2. Cut an adequate hole into the rubber grommet. Slide the grommet onto the cable.
3. Prepare the ends of the motor cable as illustrated in figures 3a and 3b (two
different motor cable types are shown). 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.
4. Slide the cable through the hole in the cable entry. and attach the grommet to t
he
hole.
5. Connect the motor cable:
• Ground the shield 360 degrees by tightening the clamp of the power cabl
e
grounding shelf onto the stripped part of the cable (5a).
• Connect the twisted shield of the cable to the grounding terminal (5b).
• Connect the phase conductors of the cable to the T1/U, T2/V and T3/W
terminals (5c). Tighten the screws to the torque given in the figure.
6. Repeat steps 2…4 for the input power cable.
7. Connect the input power cable. Connect the additional PE conductor of the cable
(7c). Tighten the screws to the torque given in the figure.
8. R1…R2, R4:
Install the grounding shelf.
9. Repeat steps 2…4 for the brake resistor cable (if used). Cut off extra phase
conductors (if any).
10.Connect the resistor cable (if used). Tighten the screws to the torque given in the
figure.
11. Put the unused rubber grommets to the holes in the cable entry.
12.Secure the cables outside the unit mechanically.
13.Ground the motor cable shield at the motor end. For minimum radio frequency
interference, ground the motor cable shield 360 degrees at the cable entry of the
motor terminal box.
