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. 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.
Conformance to EC Directives
The E5AR/E5ER-DRT Digital Controllers comply with EC Directives. To
ensure that the machine or device in which the Unit is used complies with EC
Directives, the Unit must be installed as follows:
1,2,3...
1.
You must use reinforced insulation or double insulation for the DC power
supplies used for the communications power supply, internal power supply,
and I/O power supplies.
2.
Units complying with EC Directives also conform to the Common Emission
Standard (EN61326). Radiated emission characteristics (10-m regula-
tions) 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 complies
with EC Directives.
The following example shows one means of reducing noise.

1.
Noise from the communications cable can be reduced by installing a ferrite
core on the communications cable within 10 cm of the DeviceNet Master
Unit.

Products Co., Ltd.)
