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.

UL notice - Compact Motion

Notes on motion devices
Motor overtemperature
Motor overtemperature sensing is not provided by the drive.
Application for compact motion devices
The modules are intended for use only within Beckhoff`s Programmable Controller system Listed in File E172151.
Galvanic isolation from the supply
The modules are intended for operation within circuits not connected directly to the supply mains (galvanically isolated from the supply, i.e. on transformer secondary).
Requirements for environmental conditions
For use in Pollution Degree 2 Environment only.
