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.
WIRING
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.
WIRING
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.
•
Make sure to observe the following precautions in order to prevent any damage to
the machinery or accidents due to abnormal data written to the PLC under the
influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main
circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place. As
a guideline, lay the control line at least 100mm (3.94") or more away from the
main circuit or high-voltage lines.
2) Ground the shield wire or shield of the shielded cable at one point on the PLC.
However, do not use common grounding with heavy electrical systems.
•
Make sure to properly wire to the European terminal board in accordance with the
following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described by
the above manual.
- Tightening torque should follow the specifications by the above manual.
- Twist the end of strand wire 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.
