Caution for compliance with EC Directive
•
Please use the FX
3U
-1PSU-5V 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.
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.
•
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 30V 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 the manual of the PLC to be connected.

INSTALLATION
PRECAUTIONS
•
Cut off all phases of the power source externally before starting the installation
work, thus avoiding electric shock or damages to the product.
INSTALLATION
PRECAUTIONS
•
Use the product in the environment within the general specifications described in
the PLC main unit manual (Hardware Edition). Never use the product in areas with
dust, oily smoke, conductive dusts, corrosive gas (salt air, Cl
2
, H
2
S, SO
2
, or NO
2
),
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.
Doing so may cause device failures or malfunctions.
•
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, make sure that cutting and wiring debris do
not enter the ventilation slits of the PLC.
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 could cause fires, equipment failures, and malfunctions.
•
Fit the extension cables and communication cables securely to the designated
connectors. Contact failures may cause malfunctions.
Notes
•
When a dust proof sheet is supplied with an unit, keep the sheet applied to the
ventilation slits during installation and wiring work.
•
To prevent temperature rise, do not install the PLC on a floor, a ceiling or a vertical
surface. Install it horizontally on a wall.
•
Keep a space of 50mm (1.97”) or more between the unit main body and another
device or structure. Install the unit as far away as possible from high-voltage lines,
high-voltage devices and power equipment.
Failure to do so may cause fire, equipment failures or malfunctions.
2.2.2
DIN Rail Mounting
The product can be mounted on a DIN rail (DIN46227, 35mm width).
1) Connect the extension cable (right fig. A)
to the main unit, input/output extension
unit/block and special function unit/block
on the left.

3. Wiring
WIRING PRECAUTIONS
•
Connect the AC 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 be burnt out.
•
Cut off all phases of the power source externally before starting the wiring
work, thus avoiding electric shock or damages to the product.
•
Ensure the top cover is attached to the product before turning on the power or
starting the operation after wiring work.
Failure to do so may cause electric shock.
•
The temperature rating of the cable should be 80
°
C or more.
WIRING PRECAUTIONS
•
Perform class D grounding (grounding resistance: 100
Ω
or less) to the
grounding terminal in the main unit and extension units with a 2mm2 or
thicker wire. Do not connect the grounding terminal at the same point as a
heavy electrical system (refer to section 3.3).
•
When drilling screw holes or wiring, cutting chips or wire chips should not
enter ventilation slits. This may cause fire, failures, or malfunctions.
•
Properly perform wiring to the terminal block 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.
- Termination of the wire should follow the dimensions described in the manual.
- Tightening torque should the specifications in the manual.

).
•
The grounding point should be close to the PLC, and all grounding wire should be
as short as possible.
4. Specification
DESIGN
PRECAUTIONS
•
Provide a safety circuit on the outside of the PLC so that the whole system
operates to ensure the safety even when external power supply trouble or PLC
failure occurs.
Otherwise, malfunctions or output failures may result in an accident.
1) An emergency stop circuit, a protection circuit, an interlock circuit for opposite
movements, such as normal and reverse rotations, and an interlock circuit for
preventing damage to the machine at the upper and lower positioning limits
should be configured on the outside of the PLC.
2) When the PLC CPU detects an error, such as a watch dog timer error, during
self-diagnosis, all outputs are turned off. When an error that cannot be
detected by the PLC CPU occurs in an input/output control block, output con-
trol may be disabled.
Design external circuits and mechanisms to ensure safe operations of the
machine in such a case.
3) When some sort of error occurs in a relay, triac or transistor of the output unit/
block, output may be kept on or off.
For output signals that may lead to serious accidents, design external circuits
and mechanisms to ensure safe operations of the machine.
DESIGN
PRECAUTIONS
•
Make sure to observe the precautions below in order to prevent any damage to a
machine or any wires 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 the control line 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 wire or shield of a shielded cable at one point on the PLC.
However, do not ground at the same point as high voltage lines.
STARTUP AND
MAINTENANCE
PRECAUTIONS
•
Do not disassemble or modify the PLC.
Doing so may cause failure, malfunction or fire.
* For repair, contact your local Mitsubishi Electric representative.
•
Do not drop the product or do not exert strong impact, doing so may cause
damage.
•
Do not use the chemicals for cleaning.
•
If there is the possibility of touching the PLC inside a control panel in
maintenance, make sure to discharge to avoid the influence of static electricity.
