Conformance to EC Directives
• EMC Directives
• Low Voltage Directive
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 Directives
will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel on which the OMRON devices are installed. The cus-
tomer 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: EN
61131-2
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).
CV-series products conform to EC Directives (see note). However, the following
precautions must be observed to ensure that the machine or device in which the
CV-series PLC is used conforms to EC Directives:
1. The CV-series PLC must be installed within a control panel.
2. You must use reinforced insulation or double insulation for the DC power
supplies connected to the power supply terminals on PLCs that take DC
power and for the DC power supplies connected to I/O Units. The DC power
supply connected to the power supply terminals on PLCs using DC power
must have an output hold time of at least 10 ms.
3. CV-series products conforming to EC Directives also conform to EN
61131-2 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 there-
fore confirm that the overall machine or equipment conforms to EC Direc-
tives even when using CV-series products that conform to EC Directives.
Note Of the products that appear in this manual, the following products conform to EC
Directives.
