How to obtain manuals
For product manuals or documents, consult with the Mitsubishi Electric dealer
from who you purchased your product.
Certification of UL, cUL standards
The following product has UL and cUL certification.
UL, cUL File Number:E95239
Models: MELSEC FX 3U series manufactured
from December 1st, 2009 FX 3U -2HC
Compliance with EC directive (CE Marking)
This note does not guarantee that an entire mechanical module produced in
accordance with the contents of this note will comply with the following standards.
Compliance to EMC directive and LVD directive for the entire mechanical module
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 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 Electromagnetic Compatibility (2014/30/EU) when
used as directed by the appropriate documentation.
Attention
This product is designed for use in industrial applications.

Standard
EN61131-2:2007 Compliance with all relevant aspects of the standard.
Programmable controllers EMI
- Equipment requirements • Radiated Emission
and tests • Conducted Emission

• Radiated electromagnetic field
• Fast transient burst
• Electrostatic discharge
• High-energy surge
• Voltage drops and interruptions
• Conducted RF

Caution for EC Directive
 Installation in Enclosure
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. Please secure the cabinet
door to the control cabinet (for conduction). Installation within a control cabinet
greatly affects the safety of the system and aids in shielding noise from the
programmable controller.

may
 Differential-Line-Driver (AM26C31 or equivalent) and open collector output
encoders are available for the FX 3U -2HC.
 The FX
3U -2HC has two outputs per channel. When the counter value coincides with
an output compare value, the appropriate output is set ON. The output transistors
are individually isolated to allow either sink or source connection methods.
 Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be
selected using commands in the sequence program. Allow the FX
run only after setting these mode parameters.
