[Installation Precautions]
!
CAUTION
Use the PLC in the environment that meets the general specifications contained in this Manual.
Using the PLC outside the range of the general specifications may result in electric shock, fire or
malfunction, or may damage or degrade the module.
Securely fix the module to a DIN rail or securely fix it with the CC-Link connector type metal
installation fitting.
Not doing so can cause a drop or malfunction.
Do not touch the conducted area of the module.
Doing so may cause module malfunctioning or breakdowns.
[Wiring Precautions]
!
CAUTION
Be sure to shut off all phases of the external power supply used by the system before installation
or wiring.
Not doing so can cause the product to be damaged or malfunction.
Always ground the FG pin and FG1 pin to the protective ground conductor.
Not doing so can cause a malfunction.
Wire the module correctly after confirming the rated voltage and pin layout of the product.
Not doing so can cause a fire or failure.
Ensure that no foreign matter such as chips and wire-offcuts enter the module.
Foreign matter can cause a fire, failure or malfunction.
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.
Always fit a non-wired, one-touch connector plug to the open one-touch connector for power
supply/FG.
Not doing so can cause a failure or malfunction.
When connecting the wires or cables to the module, always run them in conduits or clamp them.
Not doing so can damage the module and cables due to loose, moved or accidentally pulled
cables or can cause a malfunction due to a cable connection fault.
Do not install the control lines together with the communication cables, or bring them close to
each other. Failure to do so may cause malfunctions due to noise.
When disconnecting the communication and power supply cables from the module, do not hold
and pull the cable part.
Disconnect the cables after loosening the screws in the portions connected to the module.
Pulling the cables connected to the module can damage the module and cables or can cause a
malfunction due to a cable connection fault.
