Improper performance of work on the electrical system can result in
serious injury or death.
► Maintenance on the electrical system that does not involve HV
components (e.g. replacing fuses), where the maintenance personnel
must work near HV components and, in the event of an error, could
trigger an electrical hazard, must be performed by "electrically trained
persons". The training must include the following factual information:
- the hazard sources on the machine,
- safety measures and
- the corresponding rules of conduct.
► In order to be permitted to perform work on the HV systems of the
machine, further training as "Expert for Work on HV Intrinsically Safe
Machines" (DGUV Information 200-005) is mandated in Germany. Be
aware of, observe and comply with the corresponding legal regulations
of other countries.
