Indications 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
the 3G3AX-RX-ECT EtherCAT Communication Unit.
The information provided here is vital to safety.
Strictly observe the precautions provided.

Transporting, Installation and Wiring
Do not drop or apply a strong impact on the product.
Doing so may result in damaged parts or malfunction.
When transporting an Inverter in which this product has been installed,
hold the radiation fins of the Inverter.
Do not remove the cover from the Communication Option Unit.
Also make sure the unit fixing screws are tightened with the specified torque.
Provide an appropriate stopping device to secure safety.
In particular, note that if you enable the setting to continue operation
in case of communication error, the Inverter will not stop when an error
occurs and equipment damage may result.
Take sufficient shielding measures when using the product in the following
locations. Not doing so may result in damage to the product.
Locations subject to static electricity or other forms of noise.
Locations subject to strong magnetic fields.
Locations close to power lines.
During installation, wiring, and network setting on the Communications
Unit, please refer to applicable sections of the manual to ensure the
correct connection and configuration procedures.
When mounting the Communications Unit, be sure that the flat cable is not
pinched.
When removing the Communications Unit, do not pull on the flat cable.
Be careful about burrs of the break-outs on the inverter when mounting the
Communication Unit.
Ŷ
Maintenance and Inspection
Be sure to confirm safety before conducting maintenance,
inspection or parts replacement.
Ŷ
Operation 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.
Before starting the CPU Unit and inverter programs, check the program
contents as well as the interactions between these programs.

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
measures to reduce interference.
Overview
EtherCAT Communication Unit (3G3AX-RX-ECT) can be installed in
OMRON’s Inverters (RX-V1 series) to let you exchange various data with
the host via EtherCAT.
Installation Procedure
Check the position of the ground terminal on the inverter and cut a FG
cable into the proper length. Fit the cut edge to the ground terminal screw
and crimp a crimp terminal.
1. Power down the inverter and wait for 10 minutes before mounting the
Communications Unit.
2. Remove the digital operator, terminal cover, and front cover.
3. Cut out the two break-outs from the front cover and remove burrs.
4. Mount the conversion board and fix it with the provided screws.
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.
