Using shield cable
[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.
[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.)
