2 Starting a Sample System
2 - 22 EtherCAT Communication Unit USER’S MANUAL (I574-E1)
To conform to the EMC directives (EN61800-3), conduct the wiring work for the EtherCAT Communica-
tion Unit, so that it meets the wiring conditions described in this section. These conditions are for con-
formance of products to the EMC directives when an EtherCAT Communication Unit is installed on an
MX2/RX-V1-series inverter. The installation and wiring conditions, however, may be affected by the
devices that are connected and wiring of the system where the EtherCAT Communication Unit is
installed. It is necessary to conform to the EMC directives as an overall system.
This section describes only the parts related to the addition of the EtherCAT Communication Unit. Fol-
low the instructions in the inverter manual for the inverter installation conditions, such as the power sup-
ply line wiring, filter installation, and motor wiring clamps.
Install the 3 clamp cores shown below near the communications connectors of the communications
cables that are connected to the communications connector (IN) and the communications connector
(OUT). (If the communications cable on the OUT side is not connected, install them for the IN side
Note: Conformance to the EMC Directives can also be ensured for the 3G3AX-RX-ECT by wiring
under the conditions.
Install the FG cable with the shortest possible wiring.
Note: The overall appearance varies depending on the inverter capacity. Do not squeeze the FG cable
into the EtherCAT Communication Unit.
