Regulations and StandardsConformance to EC DirectivesApplicable Directives• EMC Directives• Low Voltage DirectiveConcepts EMC DirectivesOMRON devices that comply with EC Directives also conform to the related EMC standards so thatthey can be more easily built into other devices or the overall machine. The actual products havebeen checked for conformity to EMC standards (see the following note). Whether the products conformto 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 dependingon the configuration, wiring, and other conditions of the equipment or control panel on which theOMRON devices are installed.The customer must, therefore, perform the final check to confirm that devices and the overallmachine conform to EMC standards.* Applicable EMC (Electromagnetic Compatibility) standards are as follows:EMS (Electromagnetic Susceptibility):CS Series: EN 61131-2 and EN 61000-6-2CJ Series: EN 61000-6-2* EMI (Electromagnetic Interference):EN 61000-6-4 (Radiated emission: 10-m regulations) Low Voltage DirectiveAlways ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet therequired safety standards for the PLC (EN 61131-2). Conformance to EC DirectivesThe CJ-series PLCs comply with EC Directives. To ensure that the machine or device in which theCJ-series PLC is used complies with EC Directives, the PLC must be installed as follows:• The CJ-series PLC must be installed within a control panel.• You must use reinforced insulation or double insulation for the DC power supplies connected toDC Power Supply Units and I/O Units.• CJ-series PLCs complying with EC Directives also conform to the Common Emission Standard(EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending on theconfiguration of the control panel used, other devices connected to the control panel, wiring, andother conditions. You must therefore confirm that the overall machine or equipment complies withEC Directives.CJ2 CPU Unit Software User’s Manual31
