*) Real applicable approvals/markings see type plate on the side (product marking).

	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.

	Maximum cable length to the sensor Without additional protective measures, the maximum cable length from the EtherCAT Module to the sensor is 30 m. For longer cable lengths, suitable surge protection should be provided.
