Safety Precaution (Read these precautions before use.)

This manual classifies the safety precautions into two categories:

and .

Indicates that incorrect handling may cause
hazardous conditions, resulting in death or
severe injury.

Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or
slight personal injury or physical damage.

Depending on the circumstances, procedures indicated by
may also cause severe injury.
It is important to follow all precautions for personal safety.

.

STARTUP AND
MAINTENANCE
PRECAUTIONS

• Do not touch any terminal while the PLC's power is on.
Doing so may cause electric shock or malfunctions.

• Before cleaning or retightening terminals externally cut off all
phases of the power supply.
Failure to do so may cause electric shock.

STARTUP AND
MAINTENANCE
PRECAUTIONS

• Use the battery for memory backup correctly in FX3U Series
User's Manual - Hardware Edition.

- Use the battery only for the specified purpose.

- Connect the battery correctly.

- Do not charge, disassemble, heat, put in fire, short-circuit,

connect reversely, weld, swallow or burn the battery, or apply
excessive forces (vibration, impact, drop, etc.) to the battery.

- Do not store or use the battery at high temperatures or

expose to direct sunlight.

- Do not expose to water, bring near fire or touch liquid

leakage or other contents directly.

- Incorrect handling of the battery may cause heat excessive

generation, bursting, ignition, liquid leakage or deformation,
and lead to injury, fire or failures and malfunctions of facilities
and other equipment.

• Before modifying or disrupting the program in operation or
running the PLC, carefully read through this manual and the
associated manuals and ensure the safety of the operation.
An operation error may damage the machinery or cause accidents.

STARTUP AND
MAINTENANCE
PRECAUTIONS

• Turn off the power to the PLC before attaching or detaching the
memory cassette. If the memory cassette is attached or
detached while the PLC's power is on, the data in the memory
may be destroyed, or the memory cassette may be damaged.

• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric distributor.

•

Turn off the power to the PLC before connecting or disconnecting
any extension cable.
Failure to do so may cause equipment failures or malfunctions.

• Turn off the power to the PLC before attaching or detaching the
following devices.
Failure to do so may cause equipment failures or malfunctions.

- Display module, peripheral devices, expansion boards, and

special adapters

- Connector conversion adapter, extension blocks, and FX

Series terminal blocks

- Battery and memory cassette

DISPOSAL
PRECAUTIONS

• Please contact a certified electronic waste disposal company
for the environmentally safe recycling and disposal of your
device.
When disposing of batteries, separate them from other waste
according to local regulations.
(For details of the Battery Directive in EU countries, refer to
FX3U Series User's Manual - Hardware Edition.)

TRANSPORTATION
AND STORAGE
PRECAUTIONS

• Before transporting the PLC, turn on the power to the PLC to
check that the BATT LED is off.
If the PLC is transported with the BATT LED on or the battery
exhausted, the battery-backed data may be unstable during
transportation.

TRANSPORTATION
AND STORAGE
PRECAUTIONS

• The PLC is a precision instrument. During transportation, avoid
impacts larger than those specified in Section 2.1. Failure to do
so may cause failures in the PLC.
After transportation, verify the operations of the PLC.

• When transporting lithium batteries, follow required
transportation regulations.
(For details of the regulated products, refer to FX3U Series
User's Manual - Hardware Edition.)

Caution for compliance with EC Directive

Installation in Enclosure

Programmable logic controllers are open-type devices that must be
installed and used within conductive control boxes. Please use the
FX3U Series programmable logic controllers while installed in
conductive shielded control boxes. 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 logic controller.

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 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 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 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 induced errors can be
smoothed out by averagin g 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.

2. Installation (general specifications)

As for installation of the input/output extension units/blocks, special
adapters and expansion boards, refer to FX3U Series User's Manual

- Hardware Edition.

INSTALLATION
PRECAUTIONS

•

Use the product within the generic environment specifications
described in section 2.1 of this manual.
Never use the product in areas with excessive dust, oily smoke,
conductive dusts, corrosive gas (salt air, Cl2, H2S, SO2 or NO2),
flammable gas, vibration or impacts, or exposed to high
temperature, condensation, or rain and wind.
If the product is used in such conditions, electric shock, fire,
malfunctions, deterioration or damage may occur.

•

Do not touch the conductive parts of the product directly to avoid
failure 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 cutting or wire
debris does 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 port when installation work is completed. Failure to
do so may cause fire, equipment failures or malfunctions.

• Connect the extension cables, peripheral device cables, input/
output cables and battery connecting cable securely to their
designated connectors.
Unsecured connection may cause malfunctions.

• Turn off the power before attaching or detaching the following
devices.
Failure to do so may cause device failures or malfunctions.

- Peripheral devices, display modules, expansion boards and

special adapters

- Extension units/blocks and the FX Series terminal block

- Battery and memory cassette

*4 The PLC cannot be used at a pressure higher than the

atmospheric pressure to avoid damage.

Notes

• When a dust proof sheet is supplied with an extension unit/
block, 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 as shown in section 2.2.

• Keep a space of 50 mm (1.97”) or more between the unit main
body and another device or structure (part A). Install the unit as
far away as possible from high-voltage lines, high-voltage
devices and power equipment.
