6-2 Concepts
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 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 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): EN61000-6-2
EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
6-3 Conformance to EC Directives
The PCUs comply with EC Directives. To ensure that the machine or device in
which a PCU is used complies with EC Directives, the PCU must be installed
as follows:
1,2,3... 1. The PCU is defined as a in-panel device and must be installed within a
control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for I/O.
3. PCUs complying with EC directives also meet the common emission stan-
dard (EN61000-6-4). The measures required to ensure that the standard
is met will vary with the overall configuration of the control panel, the other
devices connected to the control panel, wiring, and other conditions. The
customer must therefore confirm that EC directives are met for the overall
machine or device, particularly for the radiated emission requirement
(10 m).
6-4 Installation within Control Panels
Unnecessary clearance in cable inlet or outlet ports, operation panel mount-
ing holes, or in the control panel door may cause electromagnetic wave leak-
age 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 con-
ductive 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.)
