INSTALLATION
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.
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, Cl
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 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
MASS devices.
Failure to do so may cause device failures or malfunctions.
(Weight):
- Peripheral devices, extension blocks, connector conversion
kg (lbs)
adapter, extension power supply units, special adapters, and
FX Series terminal blocks
- Battery and memory cassettes
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 (section 2.2 part A). Install
the unit as far away as possible from high-voltage lines, high-
voltage devices and power equipment.
