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 FX3UC (D, DS, DSS) 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 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.)

• For crimp terminals to be used for the wiring applied with 30 V AC

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 M itsubishi 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 the manufacturers’
installation requirements.
Mitsubishi Electric recommends that shielded cables be used. If no
other EMC protection is provided, then users may experience
temporary loss of accuracy between +10 %/-10 % in very heavy
industrial areas.
However, Mitsubishi Electric suggests that when adequate EMC
precautions are followed with general good EMC practice for the
users complete control system.

- Sensitive analog cables should not be laid next to or bound with

high voltage cabling. Where possible, users should run analog
cables separately.

- Good cable shielding should be used. When grounding the

shield - ensure that no 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 the user’s program in the FX3UC Series PLC main unit.
