ŶIndications and Meanings of Safety Information
Safety Precautions
The Inverter has high voltage parts inside which,
if short-circuited, might cause damage to itself or other property.
Place covers on the openings or take other precautions to make
sure that no metal objects such as cutting bits or lead wire scraps
go inside when installing and wiring.
Do not dismantle, repair or modify the product.
Doing so may result in an injury.
Do not remove the terminal cover or remove/install the
Communication Option Unit while power is being supplied or
within 10 minutes after turning the power off.
Doing so may result in a serious injury due to an electric shock.
In this instruction sheet, the following precautions and signal
words are used to provide information to ensure the safe use of

Locations close to power lines.
ŶMaintenance and Inspection
Be sure to confirm safety before conducting maintenance,
inspection or parts replacement.
ŶOperation and Adjustment
Be sure to confirm the permissible range of motors and machines before
operation because the inverter speed can be changed easily from low to high.
ŶMODBUS-RTU Communication
Once this Communication Option Unit is installed, the MODBUS-RTU
communication function of the Inverter is disabled.
Precautions for Correct Use
ŶProduct Disposal
Comply with the local ordinance and regulations when disposing of the product.
Conformance to E8 Directives
Please attach the ferrite core to each EtherCAT communications cable.
This is a Class A product. In residential areas it may cause radio
interference, in which case the user may be required to take adequate

Overview
EtherCAT Communication Unit (3G3AX-MX2-ECT) can be installed in
OMRON’s Inverters (MX2 series) to let you exchange various data with the
host via EtherCAT.
Installation Procedure
Remove the optional board cover from the Inverter and install the EtherCAT
Communication Unit and fix it with screws.
(For details, refer to the manual for installation.)
Wiring Procedure
Securely connect the EtherCAT communication cable connector to the
EtherCAT Communication Unit by inserting the connector all the way until
it clicks.
Connect the communication cable from the EtherCAT master side
to the communication connector IN of the Communication Unit.
Connect the communication connector OUT to the communication connector
IN of the next EtherCAT slave.
Do not connect the communication connector OUT of the last EtherCAT slave.
Data will not be communicated correctly if the input/output are connected
in reverse.
For communication cables, be sure to use the Category 5 straight type or
higher cables, double shielded by braid and aluminum tape.
Connent the FG cable of this unit to ground as close as possible.
Do not squeeze the FG cable into the EtherCAT Communication Unit.
