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
• 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.
• 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 power line or shield of the analog input/output cable
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, high-voltage line, or load line.
2) Ground the shield of the analog input/output cable at one point on the
signal receiving side. However, do not use common grounding with heavy
electrical systems.
• Make sure to properly wire to the terminal block (European type) 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.
- Tightening torque should follow the specifications in the 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.
• Make sure to properly wire the 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 of the PLC main unit.
- Tightening torque should follow the specifications in the manual of the
PLC main unit.

- The power supply wire should use 22-20 AWG wire.
- Wiring to a Pt100 platinum resistance thermometer should be used the
cable of it or a twisted shielded cable.

3) Termination of cable end
Strip the coating of strand wire and twist the cable core before connecting it,
or strip the coating of single wire before connecting it.
An alternative connection is to use a ferrule with insulating sleeve.

3.3 Selection of platinum resistance thermometer sensors
→ For the terminal configuration, refer to Section 1.2
Precautions on platinum resistance thermometer wiring
• Type of platinum resistance thermometer
Select Pt100 3-wire platinum resistance thermometer sensors.
This thermometer will not be affected by voltage drop in the cable connection area,
and will ensure accurate measurement.
• Separate the cable of the platinum resistance thermometer sensors from the other
motive power cables or areas easily affected by inductive noise (of the commercial
power, etc.).

3.4 Grounding
Grounding should be performed as stated below.
• The grounding resistance should be 100 Ω or less.
• Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared grounding" of the
following figure.
