[Installation Precautions]
Use the programmable controller in an environment that meets the general specifications in this manual.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
For protection of the switches, do not remove the cushioning material before installation.
Securely fix the module with a DIN rail or mounting screws. Tighten the screws within the specified torque
range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
Shut off the external power supply for the system in all phases before wiring.
Failure to do so may result in damage to the product.
After installation or wiring, attach the included terminal cover to the module before turning it on for operation.
Undertightening can cause short circuit or malfunction.
Ground the FG terminals to the protective ground conductor dedicated to the programmable controller.
Failure to do so may result in 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.
Tighten the terminal screw 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, 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.
Place the cables in a duct or clamp them.
If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or cables or
malfunction due to poor contact.
