Validity of safety parameters
The safety parameters in the technical specifications are valid for a mission time of 20 years and
a repair time of 100 hours. If a repair is not possible within 100 hours, remove the relevant

100 hours elapse, the module switches off on its own.
For repairs, follow the procedure described in section "Diagnostic messages (Page 67)".
