If the mounting surface is rough, undue force will be applied to the PC board, thereby causing nonconformities.
• When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the ventilation slits.
Failure to do so may cause re, equipment failures or malfunctions.
• Be sure to remove the dust proof sheet from the PLC’s ventilation port when installation work is completed.
Failure to do so may cause re, equipment failures or malfunctions.
• Connect extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
• Turn off the power to the PLC before attaching or detaching the following devices.
Failure to do so may cause device failures or malfunctions.
