▪ with an awareness of safety and the hazards involved.
This assumes knowledge and use of the contents of this manual, of
the relevant accident prevention regulations as well as the recog-
nised safety-related and occupational health rules.

▪ Work on the system (such as installation, connection and initial
commissioning, for example) must only be carried out by persons
who are authorised, who have successfully completed qualifying
technical or vocational training for the respective activity and who
have taken part in advanced training sessions recognised by the
relevant responsible authority.
