), flammable gas, vibration or impacts, or expose it to high temperature,
condensation, or rain and wind.
If the product is used in such conditions, electric shock, fire, malfunctions, deterioration or damage
may occur.
CAUTION
●
Do not touch the conductive parts of the product directly. Doing so may cause device failures or
malfunctions.
●
When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the
ventilation slits of the PLC. Failure to do so may cause fire, equipment failures or malfunctions.
● For product supplied together with a dust proof sheet, the sheet should be affixed to the ventilation
slits before the installation and wiring work to prevent foreign objects such as cutting and wiring
debris.
However, when the installation work is completed, make sure to remove the sheet to provide
adequate ventilation. Failure to do so may cause fire, equipment failures or malfunctions.
●
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.
●
Install the product securely using a DIN rail or mounting screws.
● Connect the expansion board and expansion adapter securely to their designated connectors. Loose
connections may cause malfunctions.
● Make sure to affix the expansion board with tapping screws. Tightening torque should follow the
specifications in the manual. If the screws are tightened outside of the specified torque range, poor
connections may cause malfunctions.
●
Work carefully when using a screwdriver such as installation of the product. Failure to do so may
cause damage to the product or accidents.
●
Connect the extension cables, peripheral device cables and input/output cables connecting cable
securely to their designated connectors. Loose connections may cause malfunctions.
●
When using an SD memory card, insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
●
Turn off the power to the PLC before attaching or detaching the following devices. Failure to do so
may cause equipment failures or malfunctions.
