Installation Precautions

Basic precautions for the installation of an EtherCAT network for the IO-Link Master Unit 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 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 placing equipment in metal cases.
Precautions When Installing Communications Cables
• To maintain the IP67 protective structure of the IO-Link Master Unit, use communications cables
with screw connectors shown in 5-5 Connected Devices on page 5-31 and tighten the connectors
to the specified tightening torque.
• To maintain the IP67 protective structure of the IO-Link Master Unit, tighten waterproof covers
shown in 5-5 Connected Devices on page 5-31 to the specified tightening torque to any unused
communications connectors.
• 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 a communications cable to one of the communications connectors of the IO-Link
Master Unit, tighten the screw connectors of the cable with a correct wiring tool.
• When you connect a communications cable to a device with RJ45 Modular Connectors, firmly insert
the communications 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.
