F – Connect the power cables
Use symmetrical shielded cable for motor cabling. If the cable shield is the sole PE
conductor, make sure that is has sufficient conductivity for the PE.
Note for frame R3: Make sure that you have an additional PE conductor in the input
power cabling. See the hardware manual for more information.
Procedure:
1. Frames R6 and R8: Remove the shroud on the power cable terminals. See figure
on page
. Frame R8: For easier installation, remove the side
plates.
2. Remove the rubber grommets from the bottom plate for the cables to be
connected. See figure
3. Cut an adequate hole into the rubber grommets. Slide the grommets onto the
cables. Attach the unused grommets to holes cone pointing downwards.
4. Prepare the ends of the cables. See figure
on page
.
The bare shield will be grounded 360 degrees. Mark the pigtail made from the
shield as a PE conductor with yellow-and-green color.
Two alternative symmetrical three-conductor cable types are shown, and one
four-conductor cable type. The four-conductor cable is only allowed for the input
power cabling.
If you use aluminum cables, put grease to the peeled aluminum cable before
connecting it to the drive.
5. Put the cables through the holes of the cable entry plate and attach the grommets
to the holes.
6. Connect the cables (use the torques defined in the figure). See figures
page
and
:
•
Ground the shield 360 degrees by tightening the clamp of the power cable
grounding shelf onto the stripped part of the cable.
•
Connect the twisted shield of the cable to the grounding terminal.
•
Use a separate grounding PE cable (6a) or a cable with a separate PE
conductor (6b) if the conductivity of the shield does not meet the requirements
for the PE conductor. If the protective PE conductor is smaller than 10 mm
2
,
you must use a second earthing conductor. See the hardware manual for
more information.
•
Frame R3: Connect the additional PE conductor of the input power cabling.
•
Connect the phase conductors of the motor cable to the T1/U, T2/V and T3/W
terminals and the phase conductors of the input cable to the L1, L2 and L3
terminals.
