4.
On the input power cable, strip the sheathing back far
enough to route individual wires.
5.
On the motor cable, strip the sheathing back far enough to
expose the copper wire shield so that the shield can be
twisted into a bundle (pigtail). Keep the bundle (pigtail) not
longer than five times its width to minimise noise radiation.
360° grounding under the clamp is recommended for the
motor cable to minimise noise radiation. In this case,
remove sheathing at the cable clamp.
6.
Route both cables through the clamps.
7.
Strip and connect the input power and motor wires and the
input power grounding wire to the drive terminals. Frame
