EXCITING TOPIC - HIGH-VOLTAGE TRAINING FOR BATTERY POWERED MATERIAL HANDLERS AND MORE
Electric vehicles are increasingly finding their way into the market, not just in the automotive sector, but also in the construction machinery industry. Special care must be taken when servicing, maintaining and handling these devices. Anyone working on a high-voltage machine must therefore undergo special qualification and instruction. For SENNEBOGEN, this currently applies to the 735 Green Efficiency Drive model series with electric travel drive and battery-powered machines from the 8 series.
In Germany, the qualification is based on DGUV 209–093, which defines different training levels. A simple machine instruction (Level S) is required for drivers, for example. To perform general, non-electrical work as a service technician, Level 1 S is required. If work is to be carried out on electrical components or if these components are to be de-energized, training as a high-voltage specialist (Level 2 S) is required.
“Hands away from orange” is the most important principle for all work on high-voltage devices. All current-carrying cables are orange and protected. However, extensive training is still required in addition to caution, as it may still be necessary to come into contact with high-voltage components during maintenance. The SENNEBOGEN Academy has been training Level 2 S – working in a de-energized state, since the beginning of 2022.
E-learning, theory and practice – the winning combination
In addition to the theoretical basic principles, a preparatory e-learning course and examination, practical training on the machines is always included. How do I rescue a person after an electric shock with the rescue rod and what protective clothing do I have to wear during high-voltage work? All this and, above all, how such a machine is safely de-energized, is part of the H-qualification. Because training in accordance with DGUV 209–093 is manufacturer-independent, the activities are also not limited to SENNEBOGEN machines. With successful HV qualification, work may also be carried out on high-voltage devices from other manufacturers after additional machine-specific instruction. This is another reason why a look under the bonnet of an electric car is included in the training.
Who can/must complete high-voltage training?
Everyone, whether driver, service technician or salesperson, who works on or drives a high-voltage machine must receive special training. It gets interesting when work is carried out on HV components or in their immediate vicinity during service and repair work, or if these components need to be removed or de-energized. Qualification according to level 2 S and prior knowledge are mandatory in this case.
Prequalification required for Level 2 S
To take part in Level 2 S, for example, you must have completed specialist training with basic electrotechnical knowledge (e.g. mechatronics technician, motor vehicle mechanic, agricultural/construction machine mechanic) and also successfully completed an extensive e-learning program. Level 3 S (working on live parts) is not currently offered.
Note: The German DGUV 209–093 is also applied in a similar way in Austria and Switzerland. Country-specific legislation must be observed for all other countries. For individual course offers for other regions please contact us.
