A
Requirement for Compliance with LVD directive
The following products have shown compliance through direct testing (of the identified standards below) and design analysis
(through the creation of a technical construction file) to the European Directive for Low Voltage (2014/35/EU) when used as
directed by the appropriate documentation.
Type: Programmable controller (open type equipment)
Models: FX5 manufactured
Caution for compliance with EC Directive
Installation in enclosure
FX5UC CPU modules are open-type devices that must be installed and used within shielded conductive control boxes.
Please use the PLCs while installed in conductive shielded control boxes. Please secure the control box lid to the control box
(for conduction). Installation within a control box greatly improves the safety of the system and aids in shielding noise from the
PLC.
Caution for when analog products are used
It is recommended to perform the following when precision of measuring and control is required.
As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary cables (dedicated
for sensors or actuators), these users should follow those manufacturers' installation requirements.
Mitsubishi Electric recommends that shielded cables be used. If no other EMC protection is provided, users may experience
temporary loss of accuracy b10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggests that if adequate EMC precautions are followed with general good EMC practice for the
user's complete control system, users should expect normal errors as specified in this manual.
• Sensitive analog cables 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 adapters/blocks or through a user's program in the FX5UC CPU module.
Perform the following when using the analog expansion adapter:

Compliance with LVD directive Remarks
EN61131-2:2007 Programmable controllers
- Equipment requirements and tests The equipment has been assessed as a component for fitting in a suitable
enclosure which meets the requirements of EN61131-2:2007.
Programmable controllers are open-type devices that must be installed and used within conductive control cabinets.
Please use the programmable controller while installed within a conductive shielded control cabinet. Installation within a
control cabinet greatly affects the safety of the system and aids in shielding noise from the programmable controller.
