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

and .

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, cut off all phases of the power
supply externally. Failure to do so in the power ON status may cause
electric shock.

• Before modifying the program in operation, forcible output, running or
stopping the PLC, read through this manual carefully, and ensure
complete safety.
An operation error may damage the machinery or cause accidents.

• Do not change the program in the PLC from two or more peripheral
equipment devices at the same time. (i.e. from an engineering tool and a
GOT) Doing so may cause destruction or malfunction of the PLC program.

• Use the battery for memory backup in conformance to the MELSEC iQ-F
FX5UC User's Manual (Hardware).

- U se the battery for the specified purpose only.

- C onnect the battery correctly.

- D o 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.

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

Indicates that incorrect handling may cause hazardous
conditions, resulting in minor or moderate injury or
property damage.

STARTUP AND
MAINTENANCE
PRECAUTIONS

- Do not store or use the battery at high temperatures or expose to direct
sunlight.

- Do n ot expose to water, bring near fire or touch liquid leakage or other
contents directly.

- W hen replacing the battery, make sure to use our specified product
(FX3U-32BL).

- W hen a battery error occurs ("BAT" LED is lit in red), follow the
description in MELSEC iQ-F FX5UC User's Manual (Hardware).

Incorrect handling of the battery may cause heat excessive generation,
bursting, ignition, liquid leakage or deformation, and lead to injury, fire or
failures and malfunction of facilities and other equipment.

STARTUP AND
MAINTENANCE
PRECAUTIONS

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

• 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.

- Peripheral devices, expansion adapter, and connector conversion adapter

- E xtension modules, bus conversion module, connector conversion
module, and battery

• 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.

• Since there are risks such as burn injuries, please do not touch the
surface of the equipment with bare hands when it is operating in an
environment which exceeds ambient temperature of 50°C.

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 on the Battery Directive in EU countries,
refer to the MELSEC iQ-F FX5UC User's Manual (Hardware).)

TRANSPORTATION
PRECAUTIONS

• When transporting the PLC with the optional battery, turn on the PLC
before shipment, confirm that the battery mode is set using a parameter
and the BAT LED is OFF, and check the battery life.
If the PLC is transported with the BAT LED ON or the battery exhausted,
the battery-backed data may be unstable during transportation.

• The PLC is a precision instrument. During transportation, avoid impacts
larger than those specified in the general specifications (Section 2.1) by
using dedicated packaging boxes and shock-absorbing palettes. Failure to
do so may cause failures in the PLC.
After transportation, verify operation of the PLC and check for damage of
the mounting part, etc.

• When transporting lithium batteries, follow required transportation
regulations. (For details on the regulated products, refer to the MELSEC
iQ-F FX5UC User's Manual (Hardware).)

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 FX5UC CPU modules while installed in conductive shielded
control panels under a general industrialenvironment.

• 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 conduc tion). Installation within a c ontrol 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 (EN61010-2-201:2013)]

• 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 actio n 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.

- Us e EN60947-1 or EN60947-3 standards.

- P lace 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 MELSEC iQ-F FX5UC User's Manual (Hardware).

As for installation of the I/O modules and expansion adapters, refer to MELSEC
iQ-F FX5UC User's Manual (Hardware).

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 dus ts, corrosive gas (salt air, Cl
or NO2), flammable gas, vibration or impacts, or expose it 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.

INSTALLATION
PRECAUTIONS

• Do not touch the conductive parts of the product directly. Doing so may
cause device failures or malfunctions.

• 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.

• Install the product on a flat surface. If the mounting surface is rough,
undue force will be applied to the PC board, thereby cau sing
nonconformities.

• Install the product securely using a DIN rail or mounting screws.

• Connect the extension cables, peripheral device cables, input/output

cables and battery connecting cable securely to their designated
connectors. Loose connections may cause 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.

- Peripheral devices, expansion adapter, and connector conversion adapter

- E xtension modules, bus conversion module, connector conversion
module, and battery
