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 extension cables, peripheral device cables, input/output cables and battery connecting cable
securely to their designated connectors.
Loose connections may cause malfunctions.
• 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
- Extension units/blocks and FX Series terminal blocks
- Battery and memory cassette
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.
• Make sure to attach the terminal cover, offered as an accessory, before turning on the power or initiating operation
after installation or wiring work.
Failure to do so may cause electric shock.
WIRING PRECAUTIONS
• Connect the AC power supply wiring to the dedicated terminals 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 terminals 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.
• Do not wire vacant terminals externally.
Doing so may damage the product.
• 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.
• Make sure to properly wire to the FX Series terminal blocks in accordance with the following precautions.
Failure to do so may cause electric shock, equipment failures, a short-circuit, wire breakage, malfunctions, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described in the manual.
