(2) Grounding treatment for the CC-Link dedicated cable
(a) Always ground the twisted cable connected to the CC-Link master station,
local station and remote station.
Since the twisted cable is a shielded cable, remove part of the outer sheath.
Then ground the exposed part of the shield indicated in the figure below as
wide a surface area as possible.

Also, ground within 30 cm (11.81.in.) from the board terminal area in addition
to grounding at the position closest to the exit of the control panel.
(b) Always use the specified cable for the CC-Link dedicated cable.
(c) For each module, do not use a ferrite core for the CC-Link dedicated cable
from the board.
(d) For each module, ground both the FG terminal and SLD terminal of the
