Certification of UL, cUL standards
Please consult with Mitsubishi Electric for information on UL, cUL standard
practices and the corresponding types of equipment.
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 FX3S 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 panel lid to
the control panel (for conduction). Installation within a control panel 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 (EN61010-2-201:2013)*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 external 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.
- Use CP30-BA 2P 1-MD 0.5A or the cutoff device having the cutoff
performance equivalent to CP30-BA 2P 1-MD 0.5A.
- 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 FX3S Series User's Manual - Hardware Edition.

3.1 Wiring
3.1.1 Cable end treatment and tightening torque
For the terminals of FX3S 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 N•m.
Do not tighten terminal screws with a torque outside the above-mentioned
range. Failure to do so may cause equipment failures or malfunctions.
•When one wire is connected to one terminal
<Reference>
•When two wires are connected to one terminal*1
<Reference>
*1 To adapt the LVD directive (EN61010-2-201:2013) of the EC
directive, avoid the wiring with two wires to the built-in terminal, and take
an appropriate action such as adding an external terminal.
For the time of compliance with the LVD directive (EN61010-2-201:2013),
refer to FX3S Series User's Manual - Hardware Edition.
DESIGN
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 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) If an overload of the 24 V DC service power supply 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 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 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
•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 5 ms, 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
attempting 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 80°C or more.
WIRING
PRECAUTIONS
•Connect the power supply wiring 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.
•Noise resistance may be lower when the L and N wires of an AC power
supply are not wired correctly.
Please wire using the correct polarity.
•Do not wire vacant terminals externally.
Doing so may damage the product.
•Perform class D grounding (grounding resistance: 100 Ωor less) to the
grounding terminal on the main unit with a wire 2 mm2or 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 main unit 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.
- Make sure to properly wire to the main unit in accordance with the rated
voltage, current, and frequency of each terminal.
- The disposal size of the cable end should follow the dimensions
described in the manual.
- Tightening torque should follow the specifications in the manual.
- Tighten the screws using a Phillips-head screwdriver No.2 (shaft
diameter 6mm (0.24”) or less). Make sure that the screwdriver does not
touch the partition part of the terminal block.
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.
