[Wiring Precautions]
CAUTION
●
Ground the FG and LG terminals to the protective ground conductor
dedicated to the programmable controller. 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 screw on the terminal block comes loose, resulting in failure.
●
Check the rated voltage and terminal layout before wiring to the module, and
connect the cables correctly. Connecting a power supply with a different
voltage rating or incorrect wiring may cause a fire or failure.
●
Connectors for external device connection must be crimped or pressed with
the tool specified by the manufacturer, or must be correctly soldered.
Incomplete connections could result in short circuit, fire, or malfunction.
●
Connect the connector to the module securely.
●
Do not install the control lines or communication cables together with the main
circuit lines or power cables. Keep a distance of 100mm or more between
them. Failure to do so may result in malfunction due to noise.
●
Place the cables in a duct or clamp them.
If not, dangling cables may swing or inadvertently be pulled, resulting in
damage to the module or cables or malfunction due to poor connection.
●
Confirm the interface type in advance and connect the cable correctly.
Connecting a cable to a different interface or incorrect wiring will cause failure
of the module and the external device.
●
Tighten the screws on the terminal block within the specified torque range.
Undertightening can cause short circuit or malfunction. Overtightening can
damage the screw and/or module, resulting in drop, short circuit, fire, or
malfunction.
●
When disconnecting the cable from the module, do not pull the cable by the
cable part.
For a cable with connector, hold the connector by hand and pull it out. For a
cable connected to a terminal block, loosen the terminal block screws first
before removing the cable.
Failure to do so may result in malfunction and damage to the module or cable.
●
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
