TROUBLESHOOTING APPENDICES INDEX
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
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
jacket as shown in Figure 9.8 and ground the exposed shield section to the
ground as much as possible.
Use shielded cables for the external wiring, and ground the shields of the external
wiring cables to the control box with the AD75CK cable clamp (Mitsubishi).
(Ground the shield section 20 to 30cm away from the module.)
(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).
