If the product is used in such conditions, electric shock, fire, malfunction, deterioration or damage
may occur.
• Install the product securely using a DIN rail or mounting screws.
• Install the product on a flat surface.
If the mounting surface is rough, undue force will be applied to the PC board, thereby causing
nonconformities.

slits.
Failure to do so may cause fire, equipment failures or malfunctions.
• Be sure to remove the dust proof sheet from the PLC's ventilation port when the installation work is
completed.
Failure to do so may cause fire, equipment failures, and malfunctions.
