BASIC PRINCIPLES
1.1
ELECTRICALLY INSTRUCTED PERSON
In order to carry out work on electrical systems and equipment, a person must at least have training as an electrically instructed
person.
However, an electrically instructed person is not authorised to autonomously set up, modify or repair electrical systems and
equipment. Such tasks may only be performed under the direction and supervision of a skilled electrician.
The electrically instructed person must be trained on all systems and equipment. This training is carried out by the senior skilled
electrician, who highlights the hazards and special features. The senior skilled electrician also ensures that the requirements and
guidelines in respect of UVV, VDE and EN standards have been complied with.
All electrically instructed persons must receiving training at least once a year on the hazards, safe handling and correct conduct
in relation to electrical systems.
Documents and work instructions must also be made available to electrically instructed persons. These must relate to the exact
machine type and indicate potential hazards and special features. The work instructions must include safe and correct replace-
ment of a connecting cable, for example.
1.2
SKILLED ELECTRICIAN FOR DEFINED TASKS
In order to autonomously carry out work on electrical systems and equipment, a person must have training as a skilled electrician
for defi ned tasks.
However, the skilled electrician for defi ned tasks must also, like the electrically instructed person, be trained on all systems and
equipment. This training is carried out by the senior skilled electrician, who highlights the hazards and special features. The
senior skilled electrician also ensures that the requirements and guidelines in respect of UVV, VDE and EN standards have been
complied with.
It is also necessary for a responsible skilled electrician to assume professional responsibility.
1.3
LEGAL FOUNDATIONS
Once a system and its equipment has been repaired, modifi ed or set up, it must not constitute any hazard for users and their
environment. To ensure that safety can still be guaranteed, an annual inspection is required for mobile systems and equipment.
1.4
WHICH TESTS MUST BE PERFORMED
A test in accordance with the guidelines of BGV A3
must
be performed and verifi ed. This test must be performed on all electrical
equipment, even if "only" a mechanical repair has been carried out.
