Book our training courses as Electrotechnically trained personnel (ETP) and Electrics specialist for defined activities (ESD) now also as open seminars with us in Stuttgart on site!



Electrotechnically trained personnel (ETP) - according to DGUV Information 209-093 - Level 1 (Qualified Instructed Person - FuP)

Brief description:

Electrotechnically instructed persons may not carry out any work on electrical systems and equipment on their own responsibility. They may only carry out work for which they have received proper instruction. During this work, they must apply the measures and rules of conduct taught. Electrical work may only be carried out under the direction and supervision of a qualified electrician.


Entry requirement :

None. Employees who perform general maintenance and service activities as well as mechanical work on certified voltage-free electric or hybrid vehicles.

Duration : 4 hours


  •  Carry out general activities that do not require de-energising the HV system.
  • Carry out all mechanical activities on the vehicle (but "hands off orange!")
  • Disconnecting the HV system, service disconnect/maintenance plug "pull and plug" as an additional safety measure.
  •  Determine the person to be contacted in case of ambiguity 
  • Impermissible work on the vehicle
  • Organisational procedure for electrotechnical work carried out under the direction and supervision of a specialist for high-voltage systems

Electrics specialist for defined activities (ESD) - according to DGUV Information 209-093 - Level 2b (Qualified Person - FHV)

Brief description:

The participants receive the specialist knowledge and skills to work on vehicles that are not HV intrinsically safe. This includes all electrotechnical work carried out in a de-energised state.

The focus is on basic knowledge of different network systems and their protective measures as well as risk assessment, work instructions and instruction. Furthermore, the individual HV components and their safety measures are dealt with. Finally, practical exercises are carried out on an electric vehicle (decommissioning and commissioning) with the switching authorisation up to 1000 V AV / 1500 V DC for high-voltage vehicles.


Entry requirement:
Employees with electrical engineering training but without authorisation to work with voltages up to 1000 V AC / 1500 V DC, i.e. persons with previous electrical engineering knowledge in the motor vehicle sector, e.g. motor vehicle electricians, motor vehicle mechatronics engineers, engineers with electrical engineering components.

Duration: 5 days

  • Legal principles (regulations, standards, directives)
  • Dangers and effects of electric current
  • Protective measures against direct and indirect contact
  • Types of protection
  • Testing of protective measures
  • Company-specific and electrotechnical requirements
  • Measures for accident prevention when working on electrical equipment
  • Basics of "first aid" for electrical accidents
  • Basics of hybrid/fuel cell technology and explosion protection
  • Risk assessment of HV vehicles
  • Mode of operation, structure, function and performance data of the components in the HV vehicle
  • HV vehicle electrical system
  • Fuse protection of the components
  • Maintenance and service of components
  • Labelling of components, instructions, hazard warnings
  • Measurements on the HV vehicle, commissioning
  • Safety briefing and instruction on the hybrid vehicle
