Training information


You are an automotive technician and want to be able to work safely on e-vehicles. You must do this according to the safety standard NEN 9140. This standard specifies which people are allowed to work on an e-vehicle, what training or instruction you must have and how you work safely.

If you want to carry out safe maintenance and repairs to the HV system, you must at least be designated as a Sufficiently Instructed Person (ev-VOP). With this instruction you can de-energize and energize the HV system. You may (dis)assemble voltage-free HV components and store e-hazardous components. So you are not allowed to work on live HV systems of an e-vehicle.

During the training you will learn to recognize the HV components of e-vehicles and what you can and cannot do with this type of vehicles. This will help you to better understand what the risks are so you know how to work safely with these vehicles. You will learn which safety measures you take in advance, which personal protective equipment (PPE) and tools you must use and which requirements they must meet. You will also learn how to de-energize the HV system. In this way you also meet the NEN 9140 standard with regard to working with electric and hybrid vehicles for Sufficiently Instructed Person (ev-VOP).
