INSTALLATION PRECAUTIONS
• Use the product within the generic environment specifications described in Section 4.1 of this manual.
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.
• Make sure to affix the expansion board with tapping screws.
Tightening torque should follow the specifications in the manual.
Loose connections may cause 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.
• Connect the extension cables, peripheral device cables, input/output cables and battery connecting cable securely to their designated
connectors.
Loose connections may cause malfunctions.
• Connect the display module, memory cassette, and expansion board 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
