[WIRING PRECAUTIONS]
[STARTUP/MAINTENANCE PRECAUTIONS]
CAUTION
Always ground the FG terminal to the protective ground conductor.
Failure to do so may cause a malfunction.
Verify the rated voltage and pin-out, and connect the external power supply cable properly.
Connecting a power supply with a different voltage rating or faulty wiring may cause a fire or failure.
Terminal screws must be tightened with the specified torque.
If a screw is loose, it may cause a short circuit, fire or malfunction.
Be careful to prevent foreign matter such as dust or wire chips from entering the module.
Failure to do so may 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 cables may swing or inadvertently be pulled, resulting in damage to the module or
cables, or malfunctions due to poor cable connection.
When disconnecting a communication cable or a power cable from the module, do not pull the cable
part.
For a cable with connectors, hold the connector by hand and disconnect it from the module.
For a cable connected to a terminal block, loosen the terminal block screws and disconnect the
cable from the module.
Pulling a cable that is still connected to the module may cause a malfunction or damage the module
and/or the cable.
A protective film is attached to the module top to prevent foreign matter such as wire chips from
entering the module during wiring.
Do not remove the film during wiring.
Be sure to remove it for heat dissipation before system operation.
CAUTION
When performing online operations (especially, program modification, forced output or operating
status change) by accessing a running CPU on another station from GX Developer via CC-Link IE
controller network, read the manual carefully and ensure the safety.
Improper operation will cause mechanical damage or accidents.
Do not disassemble or remodel each of the modules.
Doing so may cause failure, malfunctions, personal injuries and/or a fire.
