Certification of UL, cUL standards
The FX3U-232ADP-MB unit supports UL and cUL standards.
UL, cUL file number :E95239
Compliance with EC directive(CE Marking )
This document does not guarantee that a mechanical system including this product will
comply with the following standards.
Compliance to EMC directive of the entire mechanical system should be checked by
the user / manufacturer. For more details please contact the local Mitsubishi Electric
sales site.
Requirement for Compliance with EMC directive
The FX3U-232ADP-MB is compliant through direct testing (of the identified standards
below) and design analysis (through the creation of a technical construction file) to the
European Directive for Electromagnetic Compatibility (89/336/EEC) when used as
directed by the appropriate documentation.
Caution for compliance with EC Directive
Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and used
within conductive control boxes. Please use the FX3U Series programmable logic
controllers 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 affects the safety of the system and aids in shielding noise from the
programmable logic controller.
