Attention
This product is designed for use in industrial applications.
Type: Programmable Controller (Open Type Equipment)
Models: MELSEC FX3UC series manufactured
from October 1st, 2007 FX3UC-4AD
Caution for EC Directive
The FX3UC-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
FX3UC Series PLC main unit.
•Please use FX3UC-4AD while installed in a shielded enclosure. For the
details, refer to the following manual.
→ Refer to the FX3UC Series User's Manual - Hardware Edition
Note for compliance with EN61131-2:2007
General note on the use of the power supply cable.
The FX3UC-4AD unit requires that the cable used for power supply is 30m or less.
1. Outline
The FX3UC-4AD special function block (hereinafter called 4AD) for analog input
converts four analog input values (voltage, current) to digital values and transfers those
digital values to the PLC main unit. For the purpose of this manual the FX3UC-4AD will
from here be referred to as the 4AD.

Type: Programmable Controller (Open Type Equipment)
Models: MELSEC FX3UC series manufactured
from October 1st, 2007 FX3UC-4AD
Caution for EC Directive
The FX3UC-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
FX3UC Series PLC main unit.
•Please use FX3UC-4AD while installed in a shielded enclosure. For the
details, refer to the following manual.
→ Refer to the FX3UC Series User's Manual - Hardware Edition
Note for compliance with EN61131-2:2007
General note on the use of the power supply cable.
The FX3UC-4AD unit requires that the cable used for power supply is 30m or less.

place. As a guideline, lay the control line 100mm (3.94") or more away
from the main circuit, high-voltage lines, or load line.
2) Ground the twisted shield cable at one point on the PLC. However, do not
use common grounding with heavy electrical systems.
•Make sure to properly wire to the European terminal board 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.
- Tightening torque should follow the specifications in the manual.
- 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.

2) Termination
Strip the coating of strand wire and twist the cable core before connecting it,
or strip the coating of single wire before connecting it. An alternative
connection is to use a ferrule with insulating sleeve.
*1 Old model name : CRIMPFOX ZA 3
*2 Old model name : CRIMPFOX UD 6
•Stranded wire/solid wire •Ferrule with insulation sleeve
When using a ferrule with insulation sleeve, choose a wire with proper cable
sheath referring to the above outside dimensions, otherwise the wire cannot
be inserted easily.
5.1.2 Tightening Torque
Tightening torque should be between 0.22 and 0.25 N•m.
Do not tighten terminal screws with a torque outside the abovementioned range.
Failure to do so may cause equipment failures or malfunctions.
5.2 Tool
To tighten terminals, use a purchased small-
sized screwdriver whose head is straight and
is not widened as shown in the right figure.
Note:
If the diameter of screwdriver grip is too
small, tightening torque will not be able to
be achieved. To achieve the appropriate
tightening torque shown in the table above, use the following screwdriver or an
appropriate replacement (grip diameter: approximately 25mm (0.98")).
<Reference>
5.3 Power supply wiring
Supply the 24V DC power to 4AD via the power supply connector.
WIRING
PRECAUTIONS
•Make sure to observe the following precautions in order to prevent
malfunctions under the influence of noise:
1) Do not bundle the power line or twisted shielded cable 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 100mm (3.94") or more away
from the main circuit, high-voltage lines, or load line.
2) Ground the twisted shield cable at one point on the PLC. However, do not
use common grounding with heavy electrical systems.
•Make sure to properly wire to the European terminal board 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.
- Tightening torque should follow the specifications in the manual.
- 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.
