(1) Ungrounded and high-resistance ground systems do not meet the EMC Directive due to the disconnected jumper positions.
(2) Full compliance requires an optional EMC solution that is mounted in a dedicated enclosure. Rockwell Automation is evaluating the ability to meet Category C2 compliance. Contact the factory for
more information.
