Compliance with EC directive (CE Marking)
This note does not guarantee that an entire mechanical module produced in
accordance with the contents of this note will comply with the following standards.
Compliance to EMC directive and LVD directive for the entire mechanical module
should be checked by the user / manufacturer. For more information please consult
with your nearest Mitsubishi product provider.
Regarding the standards that comply with the main unit, please refer to either the FX
series product catalog or consult with your nearest Mitsubishi product provider.
Requirement for Compliance with EMC directive
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.

Caution for EC Directive
The FX
3U
-4LC 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 loss or accuracy between
±10% in very heavy industrial areas.
However, Mitsubishi Electric suggest that if adequate EMC precautions are followed 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. When terminating the shield at Earth
- ensure that no earth loops are accidentally created.
•
When reading analog values, EMC accuracy can be improved out by averaging the
readings. This can be achieved either through functions on the analog special
function blocks or through a users program in the FX
3G

Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and
used within conductive control cabinets. Please use the programmable logic
controller while installed within a conductive shielded control cabinet. Please secure
the cabinet door to the control cabinet (for conduction). Installation within a control
cabinet greatly affects the safety of the system and aids in shielding noise from the
programmable logic controller.

INSTALLATION
PRECAUTIONS
•
Do not touch the conductive parts of the product directly.
Doing so may cause device failures or malfunctions.
•
Install the product securely using a DIN rail or mounting 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 nonconformities.
•
When drilling screw holes or wiring, make sure that cutting and wiring debris
do not enter the ventilation slits.
Failure to do so may cause fire, equipment failures or malfunctions.
•
Be sure to remove the dust proof sheet from the PLC's ventilation slits when
installation work is completed.
Failure to do so may cause fire, equipment failures or malfunctions.
•
Connect extension cables securely to their designated connectors.
Loose connections may cause malfunctions.
WIRING
PRECAUTIONS
•
Make sure to cut off all phases of the power supply externally before
attempting wiring work.
Failure to do so may cause electric shock.
WIRING
PRECAUTIONS
•
Connect the AC power supply to the dedicated terminals specified in this
manual. If an AC power supply is connected to a DC input/output terminal or
DC power supply terminal, the PLC will burn out.
•
Do not wire vacant terminals externally. Doing so may damage the product.
•
Use class D grounding (grounding resistance of 100
Ω
or less) with a wire of
2mm
2
or thicker on the grounding terminal of the PLC. However, do not
connect the ground terminal at the same point as a heavy electrical system.
•
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
malfunctions under the influence of noise.
- 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 at least 100mm (3.94") or more
away from the main circuit, high-voltage line, or load line.
- Ground the shield wire or shield of the shielded cable at one point on the
PLC. However, do not use common grounding with heavy electrical
systems.
•
Make sure to properly wire to the terminal blocks in accordance with the
following precautions. Failure to do so may cause electric shock, a short-
circuit, wire breakage, or damage to the product.
- The disposal size of the cable end should follow the dimensions
described in the FX
3U
-4LC User's Manual
- Tightening torque should follow the specifications in the FX
3U
-4LC User's
Manual
3.1 Example of Input/output Wiring
*1 24V DC service power supply of the FX
3G
/FX
3U
Series PLC can also be used.
*2 When using a thermocouple, use specified compensating lead wires.
*3 When you use a resistance thermometer sensor, the resistance of the lead
wire is low, use a wire without a resistance difference between the lead wire.
*4 Make sure to short-circuit the 'PTB' and 'PTB' terminals when a 2-wire
resistance thermometer sensor is input.
3.2 Grounding
Ground the cables as follows
•
The grounding resistance should be 100
Ω
or less.
•
Independent grounding should be established whenever possible.
Independent grounding should be performed for best results.
When independent grounding is not configured, perform "shared grounding" as
shown in the following figure. For details, refer to the respective PLC manual.
→

DESIGN
PRECAUTIONS
•
Make sure to include the following safety circuits outside the PLC to ensure
safe system operation even during external power supply problems or PLC
failure. Otherwise, malfunctions may cause serious accidents.
1) Above all, the following components should be included: an emergency
stop circuit, a protection circuit, an interlock circuit for opposite movements
(such as normal vs. reverse rotation), and an interlock circuit (to prevent
damage to the equipment at the upper and lower positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer
error, during self-diagnosis, all outputs are turned off. Also, when an error
that cannot be detected by the PLC CPU occurs in an input/output
control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
3) Note that when an error occurs in a relay, triac or transistor output
device, the output could be held either on or off. For output signals that
may lead to serious accidents, external circuits and mechanisms should
be designed to ensure safe machinery operation in such a case.
DESIGN
PRECAUTIONS
•
Do not bundle the control line together with or lay it close to the main circuit
or power line. As a guideline, lay the control line at least 100mm (3.94") or
more away from the main circuit or power line. Noise may cause
malfunctions.
