[Wiring Precautions]
● Individually ground the FG and LG terminals of the programmable controller with a ground resistance
of 100 ohms or less. Failure to do so may result in electric shock or malfunction.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.
● Check the rated voltage and terminal layout before wiring to the Ethernet adapter module, and
connect the cables correctly. Connecting a power supply with a different voltage rating or incorrect
wiring may cause a fire or failure.
● Securely connect the connector to the Ethernet adapter module.
● Do not install the communication cables together with the main circuit lines or power cables. Failure to
do so may result in malfunction due to noise.
● Place the cables connected to the Ethernet adapter module in a duct or clamp them. If not, dangling
cable may swing or inadvertently be pulled, resulting in damage to the Ethernet adapter module or
cables or malfunction due to poor contact.
● Tighten the terminal block screws within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the screw and/or Ethernet adapter module,
resulting in drop, short circuit, or malfunction.
● When disconnecting the cable from the Ethernet adapter module, do not pull the cable by the cable
part. For the cable with connector, hold the connector part of the cable. Pulling the cable connected to
the Ethernet adapter module may result in malfunction or damage to the module or cable.
● Prevent foreign matter such as dust or wire chips from entering the Ethernet adapter module. Such
foreign matter can cause a fire, failure, or malfunction.
● A protective film is attached to the top of the Ethernet adapter module to prevent foreign matter, such
as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it
for heat dissipation before system operation.
● The Ethernet adapter module must be installed in a control panel. Connect the main power supply
through a relay terminal block. Wiring and replacement of the Ethernet adapter module must be
performed by qualified maintenance personnel with knowledge of protection against electric shock.
For wiring methods, refer to "Wiring" in this manual.
