Compliance with EC directive (CE Marking)
This product complies with EC directive, however, this document
does not guarantee that a mechanical system including this product
will comply with EC directive.
Compliance to EMC directive and LVD directive of the entire
mechanical system should be checked by the user/manufacturer.
For more details please contact the local Mitsubishi Electric sales
site.
Caution for compliance with EC Directive
Please use the FX3U Series programmable controllers while
installed in conductive shielded control panels under a general
industrial environment.
Programmable controllers are open-type devices that must be
installed and used within conductive control panels. 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
controller.
For the control panel, use the product having sufficient strength,
fire protectiveness and shielding property to an installation
environment.
24 V DC of the power supply must be supplied from the circuit
double/reinforced insulated from the main power supply (MAINS).
Caution for compliance with the LVD directive (EN61010-2201:2013) (*1)
To an external connection port other than AC power supply
terminal and AC input/output terminal, connect the circuit
separated from a dangerous voltage by a double/reinforced
insulation.
Between the commons having the adjacent relay output
terminals, if an external power supply is higher than 120 V AC,
the insulation is basic. Therefore, when using 120 V AC or higher
external power supply and 30 V DC/AC or lower external power
supply between the adjacent commons, do not handle 30 V DC/
AC or lower external power supply as a touchable part, (When
handling 30 V DC/AC or lower extern al power supply as a
touchable part, add a basic insulation.)
Do not wire two or more crimp terminals to one terminal. (If the
wiring with two or more wires is needed, take an appropriate
action such as adding an external terminal.)
For crimp terminals to be used for the wiring applied with 30 V AC
or higher, use the products with insulating sleeves.
Cutoff device such as a breaker or a circuit protector should be
installed in accordance with the following precautions.
- Use EN60947-1 or EN60947-3 standards.
- Place the cutoff device so that it can be operated easily.
- Specify that the cutoff device is for this equipment.
(*1) For the time of compliance with the LVD directive (EN61010-
2-201:2013), refer to FX3U Series User's Manual - Hardware
Edition.
Caution for Analog Products in use
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 performa nce 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 hig h 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 induced errors can be
smoothed out by avera ging the readings. This can be achieved
either through functions on the analog special adapter/block or
through a users program in the FX3U Series PLC main unit.

PRECAUTIONS
Make sure to have the following safety circuits outside of the
PLC to ensure safe system operation even during external
power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop
circuit, a protection circui t, an interlock circuit for op posite
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 the output current of the 24 V DC service power
supply varies depending on the model and the absence/
presence of extension blocks. If an overload occurs, the
voltage automatically drops, inputs in the PLC are
disabled, and all outputs are turned off.
External circuits and mechanisms should be designed to
ensure safe machinery operation in such a case.
4) 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 li ne at
least 100 mm (3.94") or more away from the main circuit or
power line.
Noise may cause malfunctions.
Install module so that excessive force will not be applied to
peripheral device connectors.
Failure to do so may result in wire damage/breakage or PLC
failure.
Notes
Simultaneously turn on and off the power supplies of the main
unit and extension devices.
Even if the AC power supply causes an instantaneous power
failure for less than 10 ms, the PLC can continue to operate.
Even if the DC power supply causes an instantaneous power
failure for less than 5ms, the PLC can continue to operate.
If a long-time power failure or an abnormal voltage drop occurs,
the PLC stops, and output is turned off. When the power
supply is restored, it will automatically restart (when the RUN
input is on).
WIRING
PRECAUTIONS
Make sure to cut off all phases of the power supply externally
before installation or wiring work.
Failure to do so may cause electric shock or damage to the
product.
The temperature rating of the cable should be 80C or more.
WIRING
PRECAUTIONS
Connect the AC power supply to the dedicated terminals
described 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.
Perform class D grounding (grounding resistance: 100 or
less) to the grounding terminal on the FX3U PLC main unit with
a wire 2 mm2 or thicker.
Do not use common grounding with heavy electrical systems
(refer to section 3.3).
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 properly wire to the terminal 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.
Notes
Input/output wiring 50 to 100 m (164’1” to 328’1”) long will
cause almost no problems of noise, but, generally, the wiring
length should be less than 20 m (65’7”) to ensure the safety.
Extension cables are easily affected by noise. Lay the cables
at a distance of at least 30 to 50 mm (1.19” to 1.97”) away from
the PLC output and other power lines.
3.1 Wiring
3.1.1 Cable end treatment and tightening torque
For the terminals of FX3U series PLC, M3 screws are used.
The electric wire ends should be treated as shown below.
Tighten the screws to a torque of 0.5 to 0.8 Nm.
Do not tighten terminal screws with a torque outside the above-
mentioned range.
Failure to do so may cause equipment failures or malfunctions.

3.5.2 Life of relay output contact
The product life of relay contacts considerably varies depending on
the load type used. Take care that loads generating reverse
electromotive force or rush current may cause poor conta ct or
deposition of contacts which may lead to considerable reduction of
the contact product life.
1) Inductive load
Inductive loads generate large reverse electromotive force
between contacts at shutdown which may cause arcing. At a
fixed current consumption, as the power factor (phase between
current and voltage) gets smaller, the arc energy gets larger.
The standard life of the contact used for Inductive loads, such as
contactors and solenoid valves, is 500 thousand operations at
20 VA.
The following table shows the approximate life of the relay based
on the results of our operation life test.
Test condition: 1 sec.ON / 1 sec.OFF.
The product life of relay contacts becomes considerably shorter
than the above conditions when the rush overcurrent is shut
down.
Some types of inductive loads generate rush current 5 to 15 times
the stationary current at activation. Make sure that the rush
current does not exceed the current corresponding to the
maximum specified resistance load.
2) Lamp load
Lamp loads generally generate rush current 10 to 15 times the
stationary current. Make sure that the rush current does not
exceed the current corresponding to the maximum specified
resistance load.
3) Capacitive load
Capacitive loads can generate rush current 20 to 40 times the
stationary current. Make sure that the rush current does not
exceed the current corresponding to the maximum specified
resistance load. Capacitive loads such as capacitors may be
present in electronic circuit loads including inverters.

For cautions in external wiring, refer to the following manual.
Refer to FX
Protection circuit for load short-circuiting
When a load connected to the output terminal short-circuits, the
printed circuit board may be burnt out. Fit a protective fuse on the
output circuit.
Protection circuit of contact when inductive load is used
An internal protection circuit for the relays is not provided for the
relay output circuit. It is recommended to use inductive loads with
built-in protection circuits. When using loads without built-in
protection circuits, insert an external contact protection circuit, etc.
to reduce noise and extend the product life.
1) DC circuit
Connect a diode in parallel with the load.
Use a diode (for commutation) having the following
specifications.
Reverse voltage 5 to 10 times the load voltage
Forward current Load current or more
2) AC circuit
Connect the surge absorber (combined CR components such as
a surge killer and spark killer, etc.) parallel to the load.
Select the rated voltage of the surge absorber suitable to the
output used. Refer to the table below for other specifications.
Electrostatic capacity Approx. 0.1 F
Resistance value Approx. 100 to 200
Interlock
Loads, such as contactors for normal and reverse rotations, that
must not be turned on simultaneously should have an interlock in the
PLC program and an external interlock.
Common mode
Use output contacts of the PLC in the common mode.

3.6.3 Cautions in external wiring
For cautions in external wiring, refer to the following manual.
Refer to FX3U Series User's Manual - Hardware Edition.
Protection circuit for load short-circuits
A short-circuit at a load connected to an output terminal could cause
burnout at the output element or the PCB. To prevent this, a
protection fuse should be inserted at the output.
Use a load power supply capacity that is at least 2 times larger than
the total rated fuse capacity.
Contact protection circuit for inductive loads
When an inductive load is connected, connect a diode (for
commutation) in parallel with the load as necessary.
The diode (for commutation) must comply with the following
specifications.
Reverse voltage 5 to 10 times of the load voltage
Forward current Load current or more
Interlock
Loads, such as contactors for normal and reverse rotations, that
must not be turned on simultaneously should have an interlock in the
PLC program and an external interlock.
