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
NO
2), flammable gas, vibration or impacts, or exposed 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 to avoid
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.

2.1 Generic specifications
*1 The criterion is shown in IEC61131-2.
*2 Dielectric withstand voltage and insulation resistance are
shown in the following table.
For dielectric with stand voltage test and insulation resistance test of
each product, refer to the following manual.
→ Refer to FX
3G Series User's Manual - Hardware Edition.
*3 For common grounding, refer to section 3.3.
*4 The PLC cannot be used at a pressure higher than the
atmospheric pressure to avoid damage.
*5 Input/output extension units/blocks only
INSTALLATION
PRECAUTIONS
• Connect the extension cables, peripheral device cables, input/
output cables and battery connecting cable securely to their
designated connectors.
Unsecured connection may cause malfunctions.
• Turn off the power 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 extension unit/
block, 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 50mm (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.
