Precautions when Installing Communications Cables
• Check the following items on the communications cables that are used in the network.
a) Are there any breaks?
b) Are there any shorts?
c) Are there any connector problems?
• When you connect the cable to the communications connectors on devices, 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 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.
Installing EtherCAT Communications Cables
Ethernet communications cables and connectors are used to connect the EtherCAT port of the CPU
Unit with EtherCAT slaves.
Use a straight, shielded twisted-pair cable (double shielding with aluminum tape and braiding) of
Ethernet category 5 (100BASE-TX) or higher.
The following products are recommended.
