•Low Voltage Directive
6-2 Concepts
EMC Directives
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 (see the following note). 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 Direc-
tives 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 Conformance with the EMC (Electromagnetic Compatibility) standards for
EMS (Electromagnetic Susceptibility) and EMI (Electromagnetic Interference)
vary with the model in the way shown below.
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 for the PC (EN61131-2).
