STARTUP AND

MAINTENANCE

PRECAUTIONS

• 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.

• Do not change the program in the PLC from two or more

peripheral equipment devices at the same time. (i.e. from a

programming tool and a GOT)

Doing so may cause destruction or malfunction of the PLC program.

• Use the battery for memory backup correctly in FX

Series

3UC

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.

- When replacing the battery, make sure to use our specified

product (FX

-32BL).

3U

- When a battery error occurs ("BAT" LED is lit in red), follow the

description in FX

Series User's Manual - Hardware Edition.

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 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, extension units/blocks, connector

conversion adapter, extension power supply units, special

adapters, and FX Series terminal blocks.

- Battery and memory cassettes

• 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.

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

FX

Series User's Manual - Hardware Edition.)

3UC

TRANSPORTATION

AND STORAGE

PRECAUTIONS

• Before transporting the PLC, turn on the power to the PLC to

check that 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.

TRANSPORTATION

AND STORAGE

PRECAUTIONS

• The PLC is a precision instrument. During transportation, avoid

impacts larger than those specified in 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 of the regulated products, refer to FX

Series

3UC

User's Manual - Hardware Edition.)

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 FX

(D, DS, DSS) Series programmable

3UC

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.)
