[Wiring Precautions]
● Individually ground the FG terminal of the programmable controller with a ground resistance of 100
or less.
Failure to do so may cause a malfunction.
● Check the rated voltage and terminal layout before wiring the external power supply terminal block,
and connect the cables correctly. Connecting a power supply with a different voltage rating or faulty
wiring may cause a fire or failure.
● Tighten the terminal screws within the specified torque range.
Undertightening can cause short circuit, fire, 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.
● Be sure to place the communication cables or power 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.
● When disconnecting a communication cable or a power cable from the module, do not pull the cable
part.
For the cable with connector, hold the connector part of the cable.
For a cable connected to a terminal block, loosen the terminal block screws and disconnect the cable
from the module.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.
● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring.
Do not remove the film during wiring.
Remove it for heat dissipation before system operation.
[Startup and Maintenance Precautions]
● Before performing online operations (especially, program modification, forced output, and operating
status change) for the running CPU module on another station from a peripheral over CC-Link IE
Controller Network, read relevant manuals carefully and ensure the safety.
Improper operation may damage machines or cause accidents.
● Do not disassemble or modify the module.
Doing so may cause failure, malfunction, injury, or a fire.
