Using shield cable Using conduit
(1) Use four wires (3-phase + earthing) for the power cable that are completely shielded and free from
breaks.
(2) Earth the shield in the same manner as the servomotor power cable.
(3) When not using a shield cable for the power cable, use a conventional cabtyre cable. Use a metal
conduit outside the cable.
(4) Earth the power cable on the control panel side at the contact surface of the conduit connector and
control panel side wall in the same manner as the servomotor power cable. (Mask the side wall of
the control panel with paint.)
(5) Earth at the conduit connector section in the same manner as the servomotor power cable.

PD05 cable (power supply cable)
Earth with P or U clip
(1) Use a shield cable for the cable between the
control panel and operation board.
(2) Earth the shield in the same manner as the
other cables.
(3) Insert a ferrite core in the SH11 cable at a
position within 10cm from the device.
(This provides a better effect.)
The PD05 cable is used with the MELDAS500
Series.
