[INSTALLATION PRECAUTIONS]
The module should be used under the environmental conditions listed under the general specifications in
the manual.
Using it under any other environmental conditions could cause problems such as fire, malfunction and
damage to or deterioration of the product.
The module should be fixed securely with a DIN rail or installation screws, and then make sure to tighten it
within the range of the specified torque of the installation screws.
If the screws are loose, it may result in fallout or malfunction.
Tightening the screws too far may cause damages to the screws and/or the module, resulting in fallout or
malfunction
Do not directly touch the module's conductive parts.
Doing so could cause malfunction or trouble in the module.
[WIRING PRECAUTIONS]
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.
When turning on the power or operating the module after installation or wiring work, be sure the module's
terminal covers are correctly attached.
Failure to attach the terminal covers may result in short circuit or failure.
The FG terminals should always be grounded using the class-D (class-3) or higher grounding designed
specially for the PLC.
Failure to ground these terminals may cause malfunction.
Use applicable solderless terminals and tighten them with the specified torque.If any solderless spade
terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
When wiring the module, check the rated voltage and terminal layout of the wiring, and make sure the wiring
is done correctly.
Connecting a power supply that differs from the rated voltage or wiring it incorrectly may cause fire or
failure.
Tighten the terminal screws within the range of specified torque.
If the terminal screws are loose, it may result in short circuit or malfunction.
Tightening the terminal screws too far may cause damage to the screws and/or the module, resulting in
short circuit or malfunction.
Be sure there are no foreign substances such as sawdust or wiring debris inside the module.
Such debris could cause fire, failure or malfunction.
