INSTALLATION PRECAUTIONS
• Make sure to shut down all phases of the power supply externally before installing the FX3U-CF-ADP.
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, Cl2, H2S, SO2, or NO2), 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.
• 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.
• 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.
• Connect the FX3U-CF-ADP securely to special adapter connector.
Loose connections may cause malfunctions.
• Connect the power connector of the power supply cable securely to the CF-ADP power supply connector.
Loose connections may cause malfunctions.
• When inserting a CompactFlash
TM
card into the FX3U-CF-ADP, push it into the CF card slot until the EJECT button pops out.
Loose connections may cause malfunctions.
• Before inserting/removing a CompactFlash
TM
card into/from the FX3U-CF-ADP, set the CF card ACCESS switch to OFF and confirm
that the BUFFER LED and ACCESS LED are both OFF.
Failure to do so may corrupt data within the CompactFlash
TM
card.
• When removing a CompactFlash
TM
card from the FX3U-CF-ADP, make sure to support the CompactFlash
TM
card by hand, as it may
pop out.
Failure to do so may cause the CompactFlash
TM
card to fall from the FX3U-CF-ADP and break.
• Turn off the power to the PLC before attaching or detaching the following devices.
Failure to do so may cause device failures or malfunctions.
- Peripheral devices, display modules, expansion boards and special adapters
- I/O extension units/blocks, FX Series terminal block and the special function units/blocks
- Battery and memory cassette
WIRING PRECAUTIONS
• Make sure to cut off all phases of the power supply externally before attempting wiring work.
Failure to do so may cause electric shock or damage to the product.
WIRING PRECAUTIONS
• Connect the DC power supply wiring to the dedicated terminal described in this manual.
If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will burn out.
• Connect the DC power supply wiring to the dedicated connector described in this manual.
If an AC power supply is connected to a DC power supply connector, the PLC will burn out.
• 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.
