De-energize
and re-energize.
Treat both procedures as separate tasks—because the process of re-energizing is often skipped during training, yet it is just as subject to regulations in the workplace as the process of de-energizing.

Practice de-energizing.
With current limiting.
Original manual service disconnect connector, functional pilot line, Inverter with a screw-on metal cover, HV capacitor for discharging — the complete procedure on the actual component. The trainer operates at a limited current: the procedures are real, the current stays below 5 mA. The following are tested: Inverter, traction motor, high-voltage battery, and AC compressor — using real workshop measurement equipment, at either 40 V or 202 V. Training follows workshop practice: under the supervision of competent staff and with PPE as specified in the work instructions. For the inverter test mode, the manual explicitly warns of electric shock.

Engineering Core
The procedures are real. The component is, too.
Not a replica: the manual service disconnect is an original and is functionally connected to the pilot line. Pulling it creates an open circuit—and the system reacts just as it would in the vehicle. The Inverter is housed in a metal enclosure with a screw-on cover; behind it is the high-voltage capacitor with its own measurement points.

What Makes This Trainer Special
Safety is learned through repetition.
You shouldn't practice the procedure on the vehicle—it has to be second nature. That's exactly what this trainer is for: the same procedure, as many times as you like, with faults that someone has intentionally introduced.
De-energize
400 volts on the display.
40 volts in your hand.
The device displays the voltage of a real vehicle system—it outputs 40 V. Trainees read the value they will later see in the vehicle and act accordingly. In the 202 V setting, the voltage is applied as in a real-world scenario, and the current remains below 5 mA. This also allows trainees to practice Task 7: measuring on a system that is still live.
Thirteen exercises
just for faults.
Once the cycle is complete, it's time for troubleshooting: seven error groups, set via the touchscreen and secured against accidental changes using the key switch. The trainee doesn't know what settings have been selected—but the instructor does.

In the learning path · E-Mobility
Where this trainer is located in the path.
It stands at the start of high-voltage training: before anyone works on connectors or cable assemblies, the de-energization procedure has to be second nature.
Curriculum
First the sequence. Then the faults.
The first seven modules cover the entire process—from preparation to measuring under voltage. The remaining thirteen modules focus on troubleshooting across seven categories of faults. Includes a digital curriculum and the accompanying E-Learning.

E-Learning · TPGO
The course for the trainer.
On every screen.
The TP-Lab High-Voltage Safety comes with a complete course on TPGO. It runs in the browser — tablet, phone, computer. The tasks walk through the same measurements the apprentice takes on the trainer: first the assumption, then the series of readings, then the comparison.

We'll bring it to you.
A demonstration lasts about two hours. We'll walk through the entire process of de-energizing once and then simulate a fault for you to troubleshoot.
