3. Installation
For installation/uninstallation details, refer to the respective PLC User's manual
Hardware Edition.
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
, H
S, SO
, or NO
), 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 that cutting and wiring debris
do not enter the ventilation slits of the PLC.
Failure to do so may cause fire, equipment failures or malfunctions.
• Do not touch the conductive parts of the product directly.
Doing so may cause device failures or malfunctions.
• Connect special adapter securely to their designated connectors.
Loose connections may cause malfunctions.
3.1 Connection to the PLC
This section describes the connection method to the PLC (FX
Series PLC is
3U
used for the following example).
For installation method to other PLCs, refer to the respective PLC User's manual
Hardware Edition.
Procedure
1) Turn off the power.
Disconnect all the cables connected to the PLC main unit and special adapter.
Dismount the main unit and special adapter mounted on DIN rail or mounted
directly using screws.
2) Install an expansion board to the main unit.
For installation of expansion board, refer to the following manual:
→ FX
Series User's Manual - Hardware Edition
3U
3) Remove the special adapter connector cover
on the expansion board (Right fig.A).
In case of connecting this product to another
special
adapter,
please
replace

unit' in the above description with a 'special
adapter' and perform the procedure as
indicated. (Please replace the following
procedures similarly.)
5) Connect the

Connection precautions
Connect all the high-speed I/O special adapters before connecting other
special adapters when they are used in combination.
Do not connect a high-speed I/O special adapter on the left side of a
communication or analog special adapter.

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:
- 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.

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
