Installation Precautions

Basic precautions for the installation of EtherCAT networks are provided below.
 Precautions when Installing a Network
• When you install an EtherCAT network, take sufficient safety precautions and perform the installa-
tion according to standards and specifications. (Refer to JIS X5252 or to electrical facility technical
references.)
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
placing equipment in metal cases.
 Precautions when Installing Communications Cables
• 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 com-
munications 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 dirt and dust or to oil mist
or other contaminants.
• There are limitations on the bending radius of communications cables. Check the specifications of
the communications cable for the bending radius.
