Wiring precautions

Noise resistant wiring is one of the factors for the optimum performance of the EtherNet/IP
module and highly reliable system operation.
(1) Installation of 100BASE-TX and 10BASE-T
Sufficient safety measures must be taken when installing 100BASE-TX or 10BASE-T
cables.
Consult qualified service personnel for installation, including cable termination and
trunk cable wiring.
(2) Connection cable standards
For details of connection cables, refer to the following.
(3) Wiring of control lines and communication cables
Do not install the control lines and/or communication cables together with the main
circuit lines or power cables.
Keep a distance of 100mm (3.94 inches) or more between them.
(4) Bending radius of the cable
The bending radius around the connector should be "outside diameter of the cable ×
4" or larger.
(5) Cable handling
Place the communication cables or power cables in a duct or clamp them.
Failure to do so may cause damage to the modules and/or the cables or malfunction
due to unintentional pulling of the cables.
(6) Disconnecting the cable
To disconnect a communication cable or power cable from the module, hold a
connector of the cable. Do not pull the cable.
Pulling a cable that is still connected to the module may cause damage to the module
and/or the cable or malfunction.
