Regarding the standards that comply with the main unit, please refer to either the FX
series product catalog or consult with your nearest Mitsubishi product provider.

Compliance with EC directive (CE Marking)

This note does not guarantee that an entire mechanical module produced in
accordance with the contents of this note will comply with the following standards.
Compliance to EMC directive and LVD directive for the entire mechanical module
should be checked by the user / manufacturer. For more information please consult
with your nearest Mitsubishi product provider.
Regarding the standards that comply with the main unit, please refer to either the FX

Caution for EC Directive

Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and
used within conductive control cabinets. Please use the programmable logic
controller while installed within a conductive shielded control cabinet. Please secure
the cabinet door to the control cabinet (for conduction). Installation within a control
cabinet greatly affects the safety of the system and aids in shielding noise from the
programmable logic controller.

Control cabinet

- The control cabinet must be conductive.
- Ground the control cabinet with the thickest possible grounding cable.
- To ensure that there is electric contact between the control cabinet and its door, 

connect the cabinet and its doors with thick wires. 

- In order to suppress the leakage of radio waves, the control cabinet structure 

must have minimal openings. Also, wrap the cable holes with a shielding cover 
or other shielding devices.

- The gap between the control cabinet and its door must be as small as possible 

by attaching EMI gaskets between them.

*1 These wires are used to improve the conductivity between the door and control

cabinet.

General notes on the use of the power supply cable.

- The FX

3U

-16CCL-M unit requires that the cable used for power supply is 30 m or 

less.

- When the cable used for power supply exceeds 30 m, a noise filter (Ex. TDK-

Lambda MBS1205-22 or similar) should be placed on the 24 V DC power cabling 
as close (within 500 mm) to the FX

3U

-16CCL-M termination points as possible, 

refer to following figure.

INSTALLATION 
PRECAUTIONS

Use the product within the generic environment specifications described in PLC
main unit manual (Hardware Edition).
Never use the product in areas with excessive dust, oily smoke, conductive dusts,
corrosive gas (salt air, Cl

2

, H

2

S, SO

2

, or NO

2

), 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.

Do not touch the conductive parts of the product directly. 
Doing so may cause device failures 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 that cutting and wiring debris do
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.

Make sure to attach the top cover, offered as an accessory, before turning on the
power or initiating operation after installation or wiring work. 
Failure to do so may cause electric shock.

Connect extension cables securely to their designated connectors.
Loose connections may cause malfunctions.

DESIGN
PRECAUTIONS

When executing control (data changes) to an operating PLC, construct an
interlock circuit in the sequence program so that the entire system operates
conservatively. 
In addition, when executing control such as program changes and operation
status changes (status control) to an operating PLC, thoroughly read the manual
and sufficiently confirm safety in advance. 
Especially in control from external equipment to a PLC in a remote place,
problems in the PLC may not be able to be handled promptly due to abnormality
in data transfer. 
Construct an interlock circuit in the sequence program. At the same time,
determine the actions in the system between the external equipment and the PLC
for protection against abnormalities in data transfer.

Make sure to include the following safety circuits outside the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1)Above all, the following components should be included: 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 main unit detects an error during self diagnosis, such

as a watchdog timer error, all outputs are turned off. Also, when an error that
cannot be detected by the PLC main unit 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 cases.

The version number can be checked by reading the last three digits of device D8001/
D8101.

DESIGN
PRECAUTIONS

Observe the following items. Failure to do so may cause incorrect data-writing
through noise to the PLC and result in PLC failure, machine damage or other
accident.
1)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.

2)Ground the shield wire or shield of a shielded cable. Do not use common

grounding with heavy electrical systems.

Do not apply excessive pressure to the power supply terminal block or CC-Link
connection terminal block. Excessive pressure may cause damage or error.

DISPOSAL
PRECAUTIONS

Please contact a certified electronic waste disposal company for the
environmentally safe recycling and disposal of your device.

TRANSPORTATION AND 
STORAGE PRECAUTIONS

The PLC is a precision instrument. During transportation, avoid impacts larger
than those specified in the general specifications of the PLC main unit manual.
Failure to do so may cause failures in the PLC. 
After transportation, verify the operations of the PLC.
