and spacecraft if not validated together with ebm-papst.
- Operating with fully or partially dismantled or manipulated protective
equipment.
- Operating the product under conditions other than those mentioned
in the technical data.
- Furthermore, all fields of application not mentioned under intended
use.
An in situ assessment must be conducted of the heating behavior
