[1] Use four wires (3-phase + earthing) for the power cable that are completely shielded and free from breaks.
[2] Earth the shield on both the control panel side and motor chassis side. The shield earth position on the drive unit
side must be 10cm or less from the control panel.
[3] Earth the shield with a metal P clip or U clip.
(A cable clamp fitting can be used depending on the wire size.)
[4] Directly earth the shield. Do not solder the braided shield onto a wire and earth the end of the wire.
[5] When not using a shield cable for the power cable, use a conventional cabtyre cable. Use a metal conduit outside
the cable.
[6] Earth the power cable on the control panel side at the contact surface of the conduit connector and control panel.
(Mask the side wall of the control panel with paint.)
[7] Follow the treatment shown in the example for the conduit connector to earth the power cable on the motor side.
(Example: Use a clamp fitting, etc.)
