E3NW-ECT EtherCAT Digital Sensor Communication Unit Operation Manual (E429)
Conformance to EC Directives
• EMC Directives
EMC Directives
The OMRON products described in this manual are designed so that they individually comply with
the related EMC Directives so that they can be more easily built into other devices or the overall
machine. The actual products have been checked for conformity to EMC Directives (See note)*.
Whether the products conform to the standards in the system used by the customer, however,
cannot be checked by OMRON and must be checked by the customer. EMC-related performance of
the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring,
and other conditions of the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices and the overall
machine conform to EMC standards.
* Note: Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61326-1
EMI (Electromagnetic Interference): EN 61326-1
The OMRON products described in this manual comply with the related EMC Directives. To ensure that
the machine or device in which the products are used complies with EC Directives, the products must
be installed as follows:
• The products must be installed within a control panel.
• A DC power supply with reinforced insulation or double insulation that can maintain a stable output
even if the input is interrupted for 10 ms must be used for communications power, internal power, and
I/O power. The OMRON S8JX-series Power Supply is recommended. (See note.)*
•
Products complying with EC Directives also conform to the Emission Standards (EN 61326-1).
Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the
control panel used, other devices connected to the control panel, wiring, and other conditions. You must
therefore confirm that the overall machine or equipment complies with EC Directives.
• Conformance with the EC Directives was confirmed with a system configuration using I/O wiring
lengths of less than 30 m.
* Note: Conformance with the EMC Directive was confirmed when using the recommended power supply.
