APPENDICES
A
Appendix 8 EMC and Low Voltage Directives
Appendix 8.1 Requirements for compliance with the EMC Directive
(4) Built-in Ethernet port QCPU module, Ethernet module, FL-net module, Web
server module, MES interface module, high speed data logger module, high
speed data communication module, MODBUS/TCP interface module
Precautions for using AUI cables, twisted pair cables and coaxial cables are described below.
• Always ground the AUI cables
*1
connected to the 10BASE5 connectors. Because the AUI cable is a
shielded type, strip part of the jacket as shown below and ground the exposed shield section to the ground
as much as possible.
Refer to (1) for the grounding of the shield.
*1 Make sure to install a ferrite core for the cable.
As a ferrite core, ZCAT2032 manufactured by TDK is recommended.
• Use a shielded twisted pair cable for connection to the 10BASE-T or 100BASE-TX connector.
Strip a part of the jacket as shown below and ground the exposed shield section to the ground as much as
possible.
Refer to (1) for the grounding of the shield.
• Always use double-shielded coaxial cables as 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 grounding of the shield.
*2 Make sure to install a ferrite core for the cable.
As a ferrite core, ZCAT3035 manufactured by TDK is recommended.
(5) CC-Link IE Field Network module
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 below and
ground the exposed shield section to the ground as much as possible.
