APPENDICES
App - 10
Always use the specified CC-Link dedicated cable.
Use the FG terminals of the CC-Link module and CC-Link stations as shown
below to connect to the FG line inside the control panel.

Use a CE-marked power supply to which the module power supply or external
power supply is connected. Ground the FG terminals.
(5) Antenna cable
Use antenna cable of 30m or shorter.
(6) Others
(a) Ferrite core
A ferrite core has the effect of reducing radiated noise in the 30MHz to
100MHz band.
It is recommended to attach ferrite cores if shielded cables coming out of the
control panel do not provide sufficient shielding effects.
Note that the ferrite cores must be attached at the position closest to the cable
hole inside the control panel. If attached at an improper position, the ferrite
core will not product any effect.
Attach the ferrite core to the terminal that connects to the external power
supply of the main module, 4cm (1.57 inches) away from the module.
Example
(b) Noise filter (power supply line filter)
A noise filter is a component which has an effect on conducted noise.
Attaching the filter can suppress more noise. (The noise filter has the effect of
reducing conducted noise of 10MHz or less.)
Connect a noise filter to the external power supply of a main module and the
external power supply of an extension module.
Use a noise filter with the damping characteristics equivalent to those of
MA1206 (manufactured by TDK-Lambda Corporation). Note that a noise filter
is not required if the module is used in Zone A defined in EN61131-2.
