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 stand-
ards (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 Directives
will vary depending on the configuration, wiring, and other conditions of the equip-
ment 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 Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility):EN61000-6-2
EMI (Electromagnetic Interference):EN50081-2
(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 for the PLC (EN61131-2).
CJ-series Units conform to EC Directives. For the system to conform to EC Direc-
tives, however, the following precautions must be adhered to.
1. CJ-series Units must be installed within control panels.
2. Use reinforced insulation or double insulation for the DC power supplies used
for the I/O power supplies.
3. CJ-series Units that meet EC Directives also meet the Common Emission
Standard (EN50081-2). The measure necessary to ensure that standards,
such as the radiated emission standard (10-m), are met, however, will vary
depending on the overall configuration of the control panel, the other devices
connected to the control panel and wiring. You must therefore confirm that EC
Directives are met for the overall machine or device.
