Hazard classification for high-voltage system

DANGER

The vehicle’s high-voltage system and the high-voltage battery are dangerous components that can cause burns or other injuries and even lead to a fatal electric shock.

– Any work on the high-voltage system, or on systems which could be indirectly affected by it, may only be carried out by properly trained and qualified expert personnel.

– In the event of queries or uncertainties regarding the terms "high-voltage technician" or "high-voltage expert", or those concerning the high-voltage system, the responsible importer must be contacted prior to the commencement of any work.

– Repair work must always be carried out in accordance with applicable laws and regulations, the state-of-the-art technology, any relevant accident prevention regulations (in Germany, including but not limited to the Information of the German Social Accident Insurance (DGUV) 209-093 – Qualification training for work on vehicles with high-voltage system), as well as this workshop manual.

– Only the HVT is authorised to certify that the high-voltage system has been de-energised.

– All work measures necessary for the vehicle may only be carried out by a person qualified to at least the level of electrically instructed person (EIP).

– Regardless of the work to be performed, visually inspect high-voltage components in the work area.

– High-voltage cables must not be overly bent or kinked.

– In the event of conspicuous findings or uncertainties, the high-voltage technician (HVT) or the high-voltage expert (HVE) must be consulted.

– Any work involving metal-removing, deforming and sharp-edged tools or heat sources such as welding, soldering, hot air, thermal bonding and infrared drying in the vicinity of high-voltage components and cables is prohibited. In this case the high-voltage system must be de-energised and the respective component removed or sufficiently protected.

– All listed work refers to the removal and installation or the renewal of the individual components.

– For regular maintenance work, the high-voltage system does not have to be de-energised.

For reasons of safety, the following activities must not be carried out during charging:

– Activities that prolong the charging process.

– Activities for which the vehicle must be de-energised and made safe in accordance with the ensuing hazard rating.

– Activities during which the vehicle is moved and electrical wires and connectors could be placed under strain (pulled).

– Activities during which the connected charging cable could present a danger of tripping and injury.

– Activities during which the charging cable could block work paths and emergency exit routes.

– Activities on the 12V battery.

The following activities may be carried out with the → Vehicle diagnostic tester during charging:

– The event memory and measured values may be read.

– The vehicle and control units may be identified.

Important

● Before work is carried out on the following components, the system must be de-energised by a high-voltage technician (HVT) or a high-voltage expert (HVE).
