Caution for EC Directive
The FX3U-4AD have been found to be compliant to the European standards in
the aforesaid manual and directive. However, for the very best performance
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 proprietary 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. Ground the shield of the twisted
shielded cable at one point on the PLC side.
•When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
special function block for analog input or through a users program in the
FX3U Series PLC main unit.
•Please use FX3U-4AD while installed in a shielded enclosure. For the details,
refer to the following manual.

The following products have shown compliance 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 (2014/30/EU) when
used as directed by the appropriate documentation.
Attention
This product is designed for use in industrial applications.
Type: Programmable Controller (Open Type Equipment)
Models: MELSEC FX3U series manufactured
from February 1st, 2006 FX3U-4AD
Caution for EC Directive
The FX3U-4AD have been found to be compliant to the European standards in
the aforesaid manual and directive. However, for the very best performance
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 proprietary 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. Ground the shield of the twisted
shielded cable at one point on the PLC side.
•When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
special function block for analog input or through a users program in the
FX3U Series PLC main unit.
•Please use FX3U-4AD while installed in a shielded enclosure. For the details,
refer to the following manual.

standards below) and design analysis (through the creation of a technical construction
file) to the European Directive for Electromagnetic Compatibility (2014/30/EU) when
used as directed by the appropriate documentation.
Attention
This product is designed for use in industrial applications.
Type: Programmable Controller (Open Type Equipment)
Models: MELSEC FX3U series manufactured
from February 1st, 2006 FX3U-4AD
Caution for EC Directive
The FX3U-4AD have been found to be compliant to the European standards in
the aforesaid manual and directive. However, for the very best performance
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 proprietary 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. Ground the shield of the twisted
shielded cable at one point on the PLC side.
•When reading analog values, EMC accuracy can be improved out by
averaging the readings. This can be achieved either through functions on the
special function block for analog input or through a users program in the
FX3U Series PLC main unit.
•Please use FX3U-4AD while installed in a shielded enclosure. For the details,
refer to the following manual.
