[Wiring Precautions]
WARNING
Shut off the external power supply (all phases) used in the system before installation and wiring.
Failure to do so may result in electric shock or damage to the product.
After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
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 the terminal screw 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 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.
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Failure to do so may result in malfunction due to noise.
Tighten the terminal screw within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
