• Be sure to use double-shielded coaxial cables for the coaxial cables*2 connected
to the 10BASE2 connectors. Ground the double-shielded coaxial cable by
connecting its outer shield to the ground
connecting its outer shield to the ground
Refer to (1) for the shield grounding processing.
* 1 : Make sure to install a ferrite core for the cable.
The ZCAT2032 ferrite core manufactured by TDK is recommended.
(4) CC-Link IE Field Network master/local module (with safety functions)
This section describes the precautions for using the CC-Link IE Field Network cable.
• Use the CC-Link IE Field Network cable (SCE5EW-S M).
• Because the CC-Link IE Field Network cable is a shielded type, strip part of the

(5) I/O signal lines and other communication cables
If the I/O signal lines (including common line) and other communication cables (such
as CC-Link Safety and CC-Link IE Field Network) are pulled out from the control
panel, be sure to ground the shield sections of the cables as described in (1).
