This section describes how to install the EtherNet/IP network.
Basic precautions for the installation of EtherNet/IP networks are provided below.
• When you install an EtherNet/IP network, take sufficient safety precautions and perform the installa-
tion according to all applicable standards and specifications. An expert well versed in safety mea-
sures and the standards and specifications should be asked to perform the installation.
• Do not install EtherNet/IP network equipment near sources of noise.
If the network must be installed in an area with noise, take steps to address the noise, such as plac-
ing equipment in metal cases.
• Check the following items on the communications cables that are used in the network.
Are there any breaks?
Are there any shorts?
Are there any connector problems?
• When you connect the cable to the communications connectors on devices, firmly insert the commu-
nications cable connector until it locks in place.
• Do not lay the communications cables together with high-voltage lines.
• Do not lay the communications cable near devices that generate noise.
• Do not lay the communications cables in locations subject to high temperatures or high humidity.
• Do not lay the communications cables in locations subject to excessive dust, oil mist, or other con-
taminants.
• There are limitations on the bending radius of communications cables. Check the specifications of
the communications cable for the bending radius.
