2.4 Personnel qualifications
Assembly and commissioning require basic electrical and pneumatic knowledge.
Assembly and commissioning may therefore only be carried out by qualified elec-
trical or pneumatic personnel or an instructed person under the direction and su-
pervision of qualified personnel. Qualified personnel are those who can recognize
possible hazards and institute the appropriate safety measures, due to their pro-
fessional training, knowledge, and experience, as well as their understanding of
the relevant regulations pertaining to the work to be done. Qualified personnel
must observe the rules relevant to the subject area and have qualifications ac-
cording to the Technical Rules for Operational Safety (TRBS 1203).
