Caution for EC Directive

The analog special adapters 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 care­fully. 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 induced
errors not exceeding +10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol­lowed with general good EMC practice for the users complete control system,
users should expect normal errors 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 signal receiving side.

• Please use FX

3U-4DA while installed in a shielded enclosure. For the details,

refer to the following manual.

→ Refer to the FX

3U Series User's Manual - Hardware Edition

The FX3U-4DA special function block for analog output converts digital values supplied
from PLC into analog values (voltage, current) and outputs those analog values from its
four output points.

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, Cl

2, 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.

• Do not touch the conductive parts of the product directly, thus avoiding failure or
malfunction.

• Install the product securely using the DIN rail or screws.

• Install the product on a flat surface.

If the mounting surface is rough, undue force will be applied to the PC board,
thereby causing nonconformity.

• When drilling screw holes or wiring, cutting chips or wire chips should not enter
ventilation slits.
Such an accident may cause fire, failure or malfunction.

• Be sure to remove the dust proof sheet from the PLC's ventilation port when the
installation work is completed.
Failure to do so could cause fires, equipment failures, and malfunctions.

• Fit the extension cables and communication cables securely to the designated
connectors.
Contact failures may cause malfunctions.

work in order to avoid electric shock or damage of product.

WIRING
PRECAUTIONS

• 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 of the twisted shielded cable at one point on the signal
receiving side. However, do not ground at the same point as high voltage
lines.

*3 Use a 2-core twisted shield wire for analog output line, and separate it from other

power lines or inductive lines.
*4 If there is ripple or noise in the output voltage, connect a capacitor of

approximately 0.1 to 0.47 µF 25 V in the vicinity of the signal receiving side.
*5 Ground the shielded wire at one point on the signal receiving side.

3.4 Grounding

Grounding should be performed as stated below.

• The grounding resistance should be 100Ω or less.

• Independent grounding should be performed for best results.

When independent grounding is not p erformed, perform "shared grounding"
of the following figure.

→ For details, refer to the FX

3U Series User's Manual

- Hardware Edition.

• The grounding wire size should be AWG 14 (2 mm

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 EC Directive

The analog special adapters 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 care­fully. 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 induced
errors not exceeding +10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are fol­lowed with general good EMC practice for the users complete control system,
users should expect normal errors 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 signal receiving side.

• Please use FX

3U-4DA while installed in a shielded enclosure. For the details,

refer to the following manual.

→ Refer to the FX

3U Series User's Manual - Hardware Edition

1. Outline

The FX3U-4DA special function block for analog output converts digital values supplied
from PLC into analog values (voltage, current) and outputs those analog values from its
four output points.

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, Cl

2, 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.

• Do not touch the conductive parts of the product directly, thus avoiding failure or
malfunction.

• Install the product securely using the DIN rail or screws.

• Install the product on a flat surface.

If the mounting surface is rough, undue force will be applied to the PC board,
thereby causing nonconformity.

• When drilling screw holes or wiring, cutting chips or wire chips should not enter
ventilation slits.
Such an accident may cause fire, failure or malfunction.

• Be sure to remove the dust proof sheet from the PLC's ventilation port when the
installation work is completed.
Failure to do so could cause fires, equipment failures, and malfunctions.

• Fit the extension cables and communication cables securely to the designated
connectors.
Contact failures may cause malfunctions.

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

• 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 of the twisted shielded cable at one point on the signal
receiving side. However, do not ground at the same point as high voltage
lines.

• Properly perform wiring to the terminal block following the precautions below
in order to prevent electrical shock, short, wire break, or damage to the
product.

- Termination of the wire should follow the dimensions described in this manual.

- Tightening torque should be 0.5 to 0.8 N•m.
