WIRING
PRECAUTIONS
• 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.
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
Type Wire size
Single-wire 0.3 mm 2 to 0.5 mm 2 (AWG22 to 20)
2-wire 2
2 pieces of 0.3 mm (AWG22)
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 ferrule with insulation 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 m. Do not tighten terminal screws
•
with a torque outside the above-mentioned range. Failure to do so may cause
equipment failures or malfunctions.
3.2 Power Supply Wiring
For the power supply wiring, refer to the following manual.
→ FX /FX /FX /FX /FX Series User's Manual - Analog Control Edition
3S 3G 3GC 3U 3UC
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.).

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 respective PLC User's manual Hardware Edition.

(0.31") equipment equipment
Independent grounding Shared grounding
(Best condition) (Good condition)
• The grounding wire size should be AWG 22-20 (0.3-0.5 mm
• The grounding point should be close to the PLC, and all grounding wire should be
as short as possible.

STARTUP AND
MAINTENANCE
PRECAUTIONS
• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
* For repair, contact your local Mitsubishi Electric representative.
• Do not drop the product or exert strong impact to it.
Doing so may cause damage.
DISPOSAL
PRECAUTIONS
• Please contact a certified electronic waste disposal company for the
environmentally safe recycling and disposal of your device.
TRANSPORTATION AND
STORAGE PRECAUTIONS
• The product is a precision instrument. During transportation, avoid impacts
larger than those specified in the general specifications by using dedicated
packaging boxes and shock-absorbing palettes. Failure to do so may cause
failures in the product. After transportation, verify operation of the product and
check for damage of the mounting part, etc.
