Installing the drive 53

ACH550-01 User's Manual

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° earthing 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 earthing wire to the drive terminals. Frame size

R6: See the figures on page 49.

8. Connect the bundle (pigtail) created from the motor cable

shield to the earth.

Note: Check the cable lengths according to section Wiring and

EMC considerations on page 26.
