*) Real applicable approvals/markings, see name plate on the side (product labeling)

	CE approval The CE Marking refers to the EtherCAT plug‑in module mentioned above. If the EtherCAT plug-in module is used in the production of a ready-to-use end product (PCB in conjunction with a housing), the manufacturer of the end product must check compliance of the overall system with relevant directives and CE certification. To operate the EtherCAT plug‑in modules, they must be installed in a housing.
