3-4 Conformity to EC Directives
This section explains the concepts relating to and methods for complying with EC Directives for
DeviceNet Communications Units and DeviceNet Communications Cards. The applicable directives
are the EMC Directive and Low Voltage Directive.
■
Concepts
● EMC Directive
OMRON products that comply with EC Directives are electrical components that are built into and
used in manufacturing equipment. They also conform to related EMC standards (see the following
note) so that the devices or machines into which they are built can more easily conform to the EMC
standards. The actual products have been checked for conformity to EMC standards. It is the respon-
sibilities of the customer, however, to confirm whether the products conform to the standards in the
system used by the customer.
EMC-related performance of the OMRON products that comply with EC Directives will vary depend-
ing on the configuration, wiring, and other conditions of the equipment or control panel in which the
OMRON products are installed. The customer must, therefore, perform the final check to confirm that
products and the overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61800-3
EMI (Electromagnetic Interference): EN61000-6-3
(EM61000-6-3 radiated emission: 10-m regulations)
●
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to 1,500 VDC meet the
required safety standards (EN50178).

Conformity to EC Directives
The following countermeasures must always be implemented to conform to EC Directives when
using DeviceNet Communications Units or DeviceNet Communications Cards.
