Regulations and Standards
• EMC Directives
• Low Voltage Directive
z 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 con-
form to the standards in the system used by the customer, however, must be checked by the cus-
tomer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depend-
ing 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 61000-6-2
* EMI (Electromagnetic Interference):
EN 61000-6-4 (Radiated emission: 10-m regulations)
z 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 PLC (EN 61131-2).
z Conformance to EC Directives
The CJ-series PLCs comply with EC Directives. To ensure that the machine or device in which the
CJ-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 to
DC 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 the
configuration of the control panel used, other devices connected to the control panel, wiring, and
other conditions. You must therefore confirm that the overall machine or equipment complies with
EC Directives.
