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
malfunctions 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.
3.1 Applicable cable and terminal tightening torque
3.1.1 Type terminal block (European type)
1) Wire size
- The power supply wiring and the Type K/J changeover input wiring should
use 22-20 AWG wire.
- Thermocouple wiring should use the compensating lead wire suitable for
the type of thermocouple.
→ For details of compensating lead wire, Refer to Section 3.3

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.

When using a stick terminal with insulating sleeve, choose a wire with proper
cable sheath referring to the above outside dimensions, or otherwise, the wire
cannot be inserted easily. The tightening torque must be 0.22 to 0.25 N
not tighten terminal screws exceeding the specified torque. Failure to do so
may cause equipment failures or malfunctions.

Precautions on thermocouple wiring
• Thermocouple type
- There are 2 types of thermocouples: Type K and Type J. Select the desired type.
However, be sure to connect the same type of thermocouple to all the channels.
- Use insulated thermocouple types.
• Compensating lead wire
Thermocouple Type of compensating lead wire
To connect the
thermocouple, use one of
Type K KX, KCA, KCB, KCC
the right types of
compensating lead wires.
Type J JX
The compensating lead
w i r e i n d i c a t e s t h e
temperature value of approximately 0.12 °C higher than that of the wire resistor (10
Ω). Temperature value should be used in consideration of this point.
If the compensating lead wire is very long, the wire may be easily affected by noise,
etc. It is, therefore, recommended that the length of the compensating lead wire
should be 100 m (328' 1") or less.

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.
