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
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan-
dards 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 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 (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61000-6-2
EMI (Electromagnetic Interference): EN61000-6-4
(Radiated emission: 10-m regulations)
6-1-2 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 must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. PCUs complying with EC Directives also conform to the Common Emis-
sion Standard (EN61000-6-4). With regard to the radiated emission (10-m
regulations), countermeasures will vary depending on the devices con-
nected 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 Directives.
6-1-3 Installation within Control Panel
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.)
