EC Directives
These products conform to the EMC Directive and Low-voltage Directive. For
additional information, refer to the relevant installation instructions.
EMC Directive
Rockwell Automation devices that comply with EC directives also conform to
the related EMC standards so that they can more easily be built into other devices
or the overall machine. The actual products have been checked for conformity to
EMC standards. Whether they conform to the standards in the system used by
the customer, however, must be confirmed by the customer.
EMC-related performance of Rockwell Automation devices that comply with
EMC directive vary depending on the configuration, wiring, and other
conditions of the equipment or control panel in which the Rockwell Automation
devices are installed. The customer must, therefore, perform the final check to
confirm that devices and the overall machine conform to EMC standards.
Compliance with EC Directives
DeviceNet products that comply with EC directives must be installed as follows:
• All Type IP20 DeviceNet units must be installed within control panels.
• Use reinforced insulation or double insulation for the DC power supplies
used for the communication power supply, internal- circuit power supply,
and the I/O power supplies.
• DeviceNet products that comply with EC directives also conform to the
Common Emission Standard (EN 50081-2). 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 confirm that the
overall machine or equipment complies with EC directives.
