INSTALLATION
PRECAUTIONS
Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
INSTALLATION
PRECAUTIONS
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 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.
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.
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
installation work is completed.
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 extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
WIRING PRECAUTIONS
Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.
WIRING PRECAUTIONS
Perform class D grounding (grounding resistance: 100
or less) to the shield
of the twisted shield cable (refer to subsection 3.2.3).
Do not use common grounding with heavy electrical systems (refer to the
manual of the PLC main unit).
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.
Install module so that excessive force will not be applied to communication
connectors or communication cables.
Failure to do so may result in wire damage/breakage or PLC failure.
Make sure to affix the CAN bus connector with fixing screws.
Tightening torque should follow the specifications in the manual.
Loose connections may cause malfunctions.
