6 Conformance to EC Directives
6-1 Applicable Directives
EMC Directives
6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards to that
they can be more easily built into other devices or machines. The actual products have been checked
for conformity to EMC standards (see the following note). The customer, however, must check whether
the products conform to the standard in the system used by the customer.
EMC related performance of the OMRON devices that comply with EC Directives would vary depend-
ing on the configuration, wiring, and other conditions of the equipment or control panel in which the
OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices and the overall machine
conform to EMC standards.
Note Applicable EMC (Electro-Magnetic Compatibility) standards are as follows:
EMS (Electro-Magnetic Susceptibility): EN61000-6-2,
EMI (Electro-Magnetic Interference): EN55011
EN55011 Radiated emission 10-m regulations
6-3 Conformance to EC Directives
The MC Unit complies with EC Directives. To ensure that the machine or device in which an MC Unit is
used complies with EC Directives, the MC Unit must be installed as directed below:
1. The MC Unit must be installed within a control panel.
Use a control panel like SA20-712 (Nitto Electronics) or similar to this.
2. Reinforced insulation or double insulation must be used for the DC power supplies used for the
communications and I/O power supplies.
3. MC Units complying with EC Directives also conform to the Common Emission Standard
(EN50081-2). With regard to the radiated emission (10-m regulations), countermeasures will vary
depending on the devices connected to the control panel, wiring, the configuration of the system,
and other conditions. The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EC Directions.
6-4 Installation within Control Panel
Unnecessary clearance in cable inlet or outlet ports, operation panel mounting holes, or in the control
panel door may cause electromagnetic wave leakage or interference. In this case, the product may fail
to meet EC Directives. In order to prevent such interference, fill clearances in the control panel with
conductive packing. (In places where conductive packing comes in contact with the control panel,
ensure electrical conductivity by removing the paint coating or masking these parts when painting.)
