Conformance to EC Directives
Applicable Directives
• EMC Directives
• Low Voltage Directive

EMC Directives
OMRON supplies electric devices that are used built into other devices or
manufacturing equipment. These OMRON products are designed to conform
to the related EMC standards (see note) so that the devices or equipment in
which they are used can more easily conform to EMC standards.
EMC-related performance of the OMRON devices that conform to 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
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)
■
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN 61131-2.)
Conformance to EC
Directives
CJ-series products conform to EC Directives. However, the following precau-
tions must be observed to ensure that the machine or device in which the CJ-
series PLC is used conforms to EC Directives:
1. The CJ-series PLC must be installed within a control panel.
2. You must use reinforced insulation or double insulation for the DC power
supplies used for the I/O power supplies. The DC power supply connected
to the power supply terminals on PLCs using DC power must have an out-
put hold time of at least 10 ms.
3. CJ-series products conforming to EC Directives also conform to EN
61000-6-4 for EMI. 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 conforms to
EC Directives even when using CJ-series products that conform to EC Di-
rectives.
