This section describes how to install the EtherCAT network.
To ensure that the EtherCAT communication network is installed properly, refer to IEC 61784-5-12
standard in conjunction with IEC 61918.
Basic precautions for the installation of EtherCAT networks are provided below.
• When you install an EtherCAT network, take sufficient safety precautions and perform the installation
according to all applicable standards and specifications. An expert well versed in safety measures
and the standards and specifications should be asked to perform the installation.
• Do not install EtherCAT 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.
