How to obtain manuals
For the necessary product manuals or documents, consult with the Mitsubishi
Electric dealer from where you purchase your product.
Certification of UL, cUL standards
The FX 3U -485ADP-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 FX -485ADP-MB is compliant through direct testing (of the identified standards
3U
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.
Standard
EN61131-2:2003 Compliance with all relevant aspects of the
Programmable controllers standard.
- Equipment requirements and
• Radiated Emissions
tests
• Mains Terminal Voltage Emissions
• RF immunity
• Fast Transients
• ESD
• Voltage drops and interruptions

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 FX
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.
1. Outline
The FX -485ADP-MB communication special adapter (hereinafter called 485ADP-
3U
MB) is a special adapter for RS-485 communication with a terminal block (European
may also be
type).
485ADP-MB is an isolated signal exchange unit of RS-485 serial data communication
between the PLC and RS-485 device.
The FX 3U -485ADP-MB features all functionality that is available with the FX
485ADP, except that it also has MODBUS communication available.
