[Installation Precautions]
Use the programmable controller in an environment that meets the general specifications in the
detailed manual.
Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of
the product.
Securely fix the module with a DIN rail or CC-Link connector type metal installation fitting.
Not doing so can cause a drop 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.
Individually ground the FG terminal of the programmable controller with a ground resistance of
100Ω or less.
Failure to do so may result in malfunction.
Check the rated voltage and pin 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.
Do not insert the one-touch connector plug for I/O of the one-touch connector type/connector
type compact remote I/O unit into the one-touch connector for analog I/O accidentally.
Doing so can cause the module to be damaged.
Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
Attach an unwired connector plug to an unused one-touch connector for power supply and FG.
Not doing so can cause a 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.
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.
When disconnecting the cable from the module, do not pull the cable by the cable part.
Loosen the screws of connector before disconnecting the cable.
Failure to do so may result in damage to the module or cable or malfunction due to poor contact.
Smoke and fire may occur when an overcurrent flows intermittently for a long period of time. To
avoid this, configure a safety circuit, such as an external fuse, to protect the product.
