Use the product within the generic environment specifications described in
PLC main unit manual (Hardware Edition).
Never use the product in areas with excessive dust, oily smoke, conductive
dusts, corrosive gas (salt air, Cl
2
, H
2
S, SO
2
, or NO
2
), flammable gas,
vibration or impacts, or exposed 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.
•
Make sure to cut off all phases of the power supply externally before attempt-
ing installation or wiring work.
Failure to do so may cause electric shock.
•
Use screwdrivers carefully when performing installation work, thus avoiding
accident or product damage.
•
When drilling screw holes or wiring, make sure cutting or wire debris does
not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
WIRING
