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

When unshielded cables are used, the maximum cable length is limited to 3 m.

The use of shielded cables enables a maximum cable length of 30 m to be used.

Fail-safe operation

The use of the 5 V_DC EJ9505 power supply plug-in module is recommended for fail-safe operation.

If another external 5 V power supply unit is used instead of the EJ9505 plug-in module, ensure the corresponding interference immunity and a short connection.
