WIRING
PRECAUTIONS
• Cut off all phases of power source externally, before installation or wiring work in order to avoid electric shock or damage of product.
WIRING
PRECAUTIONS
• Never let cutting chips and wire chips enter the ventilation slits of this product or
PLC when performing wiring.
Otherwise, fire, failure or malfunction may occur.
• Make sure to observe the precautions below in order to prevent any damage to a machine or any accident which might be caused by abnormal data written in the
PLC due to the influence of noise:
1) Do not lay close or bundle with the main circuit, high-voltage power line, or load line.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm (3.94") from the above when wiring.
2) Ground the shield wire or shield of a shielded cable at one point on the PLC.
However, do not ground at the same point as high voltage lines.
• Observe the following items to wire the lines to the European terminal board.
Ignorance of the following items may cause electric shock, short circuit, disconnection, or damage of the product.
- The end disposal size of the cable should follow the dimensions described in this manual.
- Tighten to a torque should follow the torque described in this manual.
- Twist the end of strands and make sure there is no loose wires.
- Do not solder-plate the electric wire ends.
- Connect only the electric wires of regulation size.
- Fix the electric wires so that the terminal block and connected parts of electric wires are not stressed directly.
Wiring precaution
• Do not attach the terminal block (replacement European terminal block) for connecting RS-485 device which is already wired to FX 3U -485-BD.
If attached as its left and right are confused, the terminal configuration becomes upside down and no communication is performed.
