Regulations and Standards
• EMC Directives
• Low Voltage Directive

EMC Directive
OMRON devices that comply with EC Directives also conform to the related EMC standards 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 standards.*
Whether the products conform to the standards in the system used by the customer, however, 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.
* Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN 61131-2 and EN 61000-6-2
EMI (Electromagnetic Interference): EN 61131-2 and EN 61000-6-4 (Radiated emission: 10-m regulations)

Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the
required safety standards. The applicable directive is EN 61131-2.
