3.1 Applicable cable and terminal tightening torque
3.1.1
Terminal block (European type)
1) Wire size
- The power supply wire should use 22-20 AWG wire.
2) Applicable 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.
*1 Old model name: CRIMPFOX ZA 3
*2 Old model name: CRIMPFOX UD 6
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 0.25N
•
m. Do not tighten terminal screws
exceeding the specified torque. Failure to do so may cause equipment failures
or malfunctions.

PRECAUTIONS
•
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 terminal board (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.
- Tighten to torque should follow the torque described 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 to the FX

Series PLC 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.

3.3 Selection of resistance thermometer sensors
→
For the terminal layout, refer to Section 1.2
Precautions on resistance thermometer wiring
•
When using a 2-wire temperature sensor type, short-circuit the [L-] terminal and the
[I-] terminal. For the lead wire use a 10
Ω
resistance or less per line.
•
Separate the cable of the resistance thermometer sensors from the other power
cables or areas easily affected by inductive noise (of the commercial power, etc.).
Example of resistance thermometer wiring
*1 24V DC service power supply of the FX
3G
/FX
3U
Series PLC can also be used.
*2 When using a 2-wire temperature sensor type, short-circuit the [L
-] terminal
and the [I
-] terminal.
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.
For details, refer to the following manual.

•
The grounding wire size should be AWG 22-20 (0.3-0.5 mm
2
).
•
The grounding point should be close to the PLC, and all grounding wire should be
as short as possible.
