Caution for EC Directive
The analog special adapters have been found to be compliant to the European
standards in the aforesaid manual and directive. However, for the very best per-
formance from what are in fact delicate measuring and controlled output device
Mitsubishi Electric would like to make the following points;
As analog devices are sensitive by nature, their use should be considered care-
fully. For users of pr-oprietary cables (integral with sensors or actuators), these
users should follow those manufacturers installation requirements.
Mitsubishi Electric recommend that shielded cables should be used. If NO other
EMC protection is provided, then users may experience temporary loss or
accuracy between ±10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol-
lowed for the users complete control system, users should expect accuracy as
specified in this manual.
•Sensitive analog cable should not be laid in the same trunking or cable
conduit as high voltage cabling. Where possible users should run analog
cables separately.
•Good cable shielding should be used. When terminating the shield at Earth
- ensure that no earth loops are accidentally created.
•When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
analog special adapters or through a users program in the FX3U(C) Series
PLC main unit.

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 be 9mm (0.35").
- Tightening torque should be between 0.22 and 0.25N•m.
- 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 FX3G/FX3U/FX3UC Series PLC in
accordance with the following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or

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.
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.
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.
3.2 Power Supply Wiring
→ For the power supply wiring, refer to the FX3G / FX3U / FX3UC Series
User’s Manual - Analog Control Edition
3.3 Selection of thermocouple
→ For the terminal configuration, refer to Section 1.2
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
To connect the
thermocouple, use one of
the right types of
compensating lead wires.
The compensating lead
wire indicates the
temperature value of approximately 0.12°C higher than that of the wire resistor
(10Ω). 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.
Example of thermocouple wiring
*1 When using the Type J thermocouple, short-circuit the 'Type J' terminals and turn
the special auxiliary relay (Type K/J mode changeover) ON.
→ For details of auxiliary relays, refer to the FX3G / FX3U / FX3UC Series
User's Manual - Analog Control Edition

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 be 9mm (0.35").
- Tightening torque should be between 0.22 and 0.25N•m.
- 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 FX3G/FX3U/FX3UC Series PLC 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

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.
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.
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.
3.2 Power Supply Wiring
→ For the power supply wiring, refer to the FX3G / FX3U / FX3UC Series
User’s Manual - Analog Control Edition
3.3 Selection of thermocouple
→ For the terminal configuration, refer to Section 1.2
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
To connect the
thermocouple, use one of
the right types of
compensating lead wires.
The compensating lead
wire indicates the
temperature value of approximately 0.12°C higher than that of the wire resistor
(10Ω). 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.
Example of thermocouple wiring
*1 When using the Type J thermocouple, short-circuit the 'Type J' terminals and turn
the special auxiliary relay (Type K/J mode changeover) ON.
→ For details of auxiliary relays, refer to the FX3G / FX3U / FX3UC Series

Caution for EC Directive
The analog special adapters have been found to be compliant to the European
standards in the aforesaid manual and directive. However, for the very best per-
formance from what are in fact delicate measuring and controlled output device
Mitsubishi Electric would like to make the following points;
As analog devices are sensitive by nature, their use should be considered care-
fully. For users of pr-oprietary cables (integral with sensors or actuators), these
users should follow those manufacturers installation requirements.
Mitsubishi Electric recommend that shielded cables should be used. If NO other
EMC protection is provided, then users may experience temporary loss or
accuracy between ±10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol-
lowed for the users complete control system, users should expect accuracy as
specified in this manual.
•Sensitive analog cable should not be laid in the same trunking or cable
conduit as high voltage cabling. Where possible users should run analog
cables separately.
•Good cable shielding should be used. When terminating the shield at Earth
- ensure that no earth loops are accidentally created.
•When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
analog special adapters or through a users program in the FX3U(C) Series
PLC main unit.

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 be 9mm (0.35").
- Tightening torque should be between 0.22 and 0.25N•m.
- 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 FX3G/FX3U/FX3UC Series PLC 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 in this manual.
- Tightening torque should follow the specifications in this manual.

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.
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.
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.
3.2 Power Supply Wiring
→ For the power supply wiring, refer to the FX3G / FX3U / FX3UC Series
User’s Manual - Analog Control Edition
3.3 Selection of thermocouple
→ For the terminal configuration, refer to Section 1.2
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
To connect the
thermocouple, use one of
the right types of
compensating lead wires.
The compensating lead
wire indicates the
temperature value of approximately 0.12°C higher than that of the wire resistor
(10Ω). 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.
Example of thermocouple wiring
*1 When using the Type J thermocouple, short-circuit the 'Type J' terminals and turn
the special auxiliary relay (Type K/J mode changeover) ON.
→ For details of auxiliary relays, refer to the FX3G / FX3U / FX3UC Series
User's Manual - Analog Control Edition
*2 24V DC service power supply of the FX3G/FX3U Series PLC can also be used.
