[INSTALLATION PRECAUTIONS]
CAUTION
● Do not touch the conductive parts of the product directly. Doing so may cause device failures or
malfunctions.
● When drilling screw holes or wiring, make sure that cutting and wiring debris do not enter the
ventilation slits of the PLC. Failure to do so may cause fire, equipment failures or malfunctions.
● For the product supplied together with a dust proof sheet, the sheet should be affixed to the ventilation
slits before the installation and wiring work to prevent foreign objects such as cutting and wiring
debris.
However, when the installation work is completed, make sure to remove the sheet to provide
adequate ventilation. Failure to do so may cause fire, equipment failures or malfunctions.
● 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.
● Install the product securely using a DIN rail or mounting screws.
● Work carefully when using a screwdriver such as installation of the product. Failure to do so may
cause damage to the product or accidents.
● 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, expansion board, expansion adapter, and connector conversion adapter
- Extension modules, bus conversion module, and connector conversion module
- Battery
[WIRING PRECAUTIONS]
WARNING
● 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, provided as an accessory, before turning on the power or
initiating operation after installation or wiring work. Failure to do so may cause electric shock.
● Don't use the input terminals for measurement on a main circuit, since those terminals have no
measurement category.
● The temperature rating of the cable should be 80 or more.
● Make sure to properly wire to the spring clamp terminal block 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.
- Twist the ends of stranded wires and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected parts are directly
stressed.
