procedure as indicated.
4) Slide the special adapter slide lock (Right
fig.B) of the main unit.
In case of connecting this product to another
special adapter, please replace the 'main
unit' in the above description with a 'special
adapter' and perform the procedure as
indicated. (Please replace the following
procedures similarly.)
INSTALLATION
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.
INSTALLATION
PRECAUTIONS
•
Use the product within the generic environment specifications described in
PLC main unit manual (Hardware Edition).
Never use the product in areas with excessive dust, oily smoke, conductive
dusts, corrosive gas (salt air, Cl
2
, H
2
S, SO
2
, or NO
2
), flammable gas,
vibration or impacts, or expose it to high temperature, condensation, or rain
and wind.
If the product is used in such conditions, electric shock, fire, malfunctions,
deterioration or damage may occur.
•
When drilling screw holes or wiring, make sure cutting or wire debris does not
enter the ventilation slits.

Wiring precaution
•
Do not attach the terminal block (replacement European terminal block) for
connecting RS-485 device which is already wired to FX

If attached as its left and right are confused, the terminal configuration becomes
upside down and no communication is performed.
5. Specification
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 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 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 of the PLC main unit.
- Tightening torque should follow the specifications in the manual of the PLC
main unit.
- 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.
STARTUP AND
MAINTENANCE
PRECAUTIONS
•
Do not disassemble or modify the unit.
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.
