Si je comprends bien l'image, l'interrupteur d'urgence commute le conducteur neutre.
Ceci est dangereux car la machine est toujours sous tension.
Il faut toujours couper le phase.
If i get it right the emergency stop is connected to neutral.
That ist dangerous, because even on stop, the mashine has still power, although the mashine is not running.
Always the phase should be switched.
