Approvals and conformity	EJ5101-0090
Approvals/markings*	CE, UKCA

*) 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.

	Compliance with the common mode range The differential signal must be in the Common Mode range (<+13.2 V and >-10 V, in relation to GND), levels outside this range can lead to destruction (see interface level).
