[INSTALLATION PRECAUTIONS]
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 programmable controller. 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
