Procedure
1.
Strip the motor cable, the DC supply cable, and the brake resistor cable. See
.
2.
To move the cables through the grommets, cut them open. Use the grommets delivered in the accessories bag.
•
Do not cut the grommet openings wider than what is necessary for the used cables.
•
If the grommets fold in when putting the cable, pull the cable back to make the grommets straight.
•
Use a grommet as an alternative to the grommet in types where it is necessary.
3.
Attach the grommet and the cable until the frame of the drive goes into the groove of the grommet.
•
With the protection rating IP54 (UL Type 12), the connection between the grommet and the cable must be tight. Pull the first
bit of the cable out of the grommet until it stays straight.
•
If it is not possible, make the connection tight with some insulation tape or a cable tie.

Connect the cables. See the correct tightening torques in
12.6 Tightening Torques of the Terminals
.
•
Connect the phase conductors of the DC supply cable and of the motor cable into the correct terminals. If a brake resistor
cable is used, connect its conductors into the correct terminals.
•
Attach the grounding conductor of each cable to a grounding terminal with a grounding clamp for grounding conductor.
5.
To make a 360° connection with the grounding clamp for cable shield, expose the shield of all cables.
6.
. Make sure that the control cables or the cables of the AC drive are not caught between the frame and the cable
cover.
Additional tightening torques:
•
motor cable entry plate: 2.4 Nm
•
control cable entry plate: 0.8 Nm
•
DC cover: 2.4 Nm
7.
Attach the grounding clamps for control cable on the grounding level with M4x16 screws. Use the clamps delivered in the
accessories bag. Use the clamps to ground the control cables.
