INSTALLATION
PRECAUTIONS
Use the product within the generic environment specifications
described in section 2.1 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 failure 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 cutting or wire
debris does 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 the FX Series terminal block
- Battery and memory cassette
Notes
When a dust proof sheet is supplied with an unit, keep the
sheet applied to the ventilation slits during installation and
wiring work.
To prevent temperature rise, do not install the PLC on a floor, a
ceiling or a vertical surface.
Install it horizontally on a wall as shown in section 2.2.
Keep a space of 50 mm (1.97”) or more between the unit main
body and another device or structure (part A). Install the unit as
far away as possible from high-voltage lines, high-voltage
devices and power equipment.
WIRING
PRECAUTIONS
Cut off all phases of the power supply externally before
installation or wiring work in order to avoid damage to the
product or electric shock.
