In DGUV Information 209-093 there are 2 training paths:
All training courses for research, development and manufacturing are marked with an "E".
Training courses according to educational path "E" are intended to enable independent work on new or unknown high-voltage systems.
Individuals who work only with series vehicles are able to take training courses with an "S".
These high-voltage training courses are shorter compared to "E" and meant to be complemented by specific product trainings provided by the manufacturers.
