Certification of UL, cUL standards
The FX3U-485ADP-MB unit supports UL and cUL standards.
UL, cUL file number :E95239
Compliance with EC directive(CE Marking )
This document does not guarantee that a mechanical system including this product will
comply with the following standards.
Compliance to EMC directive of the entire mechanical system should be checked by
the user / manufacturer. For more details please contact the local Mitsubishi Electric
sales site.
Requirement for Compliance with EMC directive
The FX3U-485ADP-MB is compliant through direct testing (of the identified standards
below) and design analysis (through the creation of a technical construction file) to the
European Directive for Electromagnetic Compatibility (89/336/EEC) when used as
directed by the appropriate documentation.
Caution for compliance with EC Directive
Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and used
within conductive control boxes. Please use the FX3U Series programmable logic
controllers while installed in conductive shielded control boxes. Please secure the
control box lid to the control box (for conduction). Installation within a control box
greatly affects the safety of the system and aids in shielding noise from the
programmable logic controller.

INSTALLATION
PRECAUTIONS
•Cut off all phases of the power source externally before starting the
installation or wiring work, thus avoiding electric shock or damages to the
product.
INSTALLATION
PRECAUTIONS
•Use the product in the environment within the general specifications
described in PLC main unit manual (Hardware Edition).
Never use the product in areas with dust, oily smoke, conductive dusts,
corrosive gas (salt air, Cl2, H2S, SO2, or NO2), flammable gas, vibrations or
impacts, or expose it to high temperature, condensation, or wind and rain.
If the product is used in such a place described above, electrical shock, fire,
malfunction, damage, or deterioration may be caused.

4. Wiring
For details of wiring, refer to FX Series User's Manual - Data Communication Edition,
and FX3U Series User’s Manual - MODBUS Serial Communication Edition.
Wiring precaution
•Do not attach the terminal block (replacement European terminal block) for
connecting RS-485 device which is already wired to FX3U-485-BD.
If attached as its left and right are confused, the terminal configuration becomes
upside down and no communication is performed.

WIRING
PRECAUTIONS
•Cut off all phases of power source externally, before installation or wiring work in
order to avoid electric shock or damage of product.
WIRING
PRECAUTIONS
•Never let cutting chips and wire chips enter the ventilation slits of this product or
PLC when performing wiring.
Otherwise, fire, failure or malfunction may occur.
•Make sure to observe the precautions below in order to prevent any damage to a
machine or any accident which might be caused by abnormal data written in the
PLC due to the influence of noise:
1) Do not lay close or bundle with the main circuit, high-voltage power line, or
load line.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm (3.94") from the above when
wiring.
2) Ground the shield wire or shield of a shielded cable at one point on the PLC.
However, do not ground at the same point as high voltage lines.
•Observe the following items to wire the lines to the European terminal board.
Ignorance of the following items may cause electric shock, short circuit,
disconnection, or damage of the product.
- The end disposal size of the cable should follow the dimensions described in
this manual.
- Tighten to a torque should follow the torque described in this manual.
- Twist the end of strands and make sure there is no loose wires.
- Do not solder-plate the electric wire ends.
- Connect only the electric wires of regulation size.
- Fix the electric wires so that the terminal block and connected parts of electric
wires are not stressed directly.
