EMC Directives
EMC Directives stipulate that the system must comply with both EMS and EMI standards
(see the following note). Because OMRON devices are designed for installation in various
equipment or machines, they comply with the relevant EMC standards so that the equip-
ment or machines can easily comply with the EMC standards. However, the systems used
by customers are diverse, and EMC-related performance of the OMRON devices that com-
ply with EC Directives will vary depending on the configuration, wiring, and other conditions
of the equipment or control panel in which the OMRON devices are installed. The customer
must, therefore, perform final checks to confirm that devices and the overall machine con-
form to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2
EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC or 75 to 1,500 V DC
meet the required safety standards (EN61131-2).
