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 FX3U Series programmable 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 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.
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.)
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 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.
- 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 FX3U Series User's Manual - Hardware
Edition.
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 averaging 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.
