Question on the pink cable

Question

Asking on behalf of a user:

I have a question regarding the pink cable that is used to land on the chassis of a device. In an internal combustion device, I understand well that this cable is connected to the chassis because the negative cable of the 12-volt battery is also connected in that position. But what I still don't understand is whether said pink cable should be connected or not if the equipment is electrically powered, for example 48 volts, and whose negative is not connected to the chassis. In that case, does it make any sense to connect the pink cable to the chassis?

Hello there!😁Thank you for your question!😸The answer is quite simple: If the negative is not connected on the chassis then you don’t need the pink wire for the installation.Please let me know if you have further questions😊Have a great one!

Thank you very much for the explanation. The reason for the question is because in my workplace they indicate that it is mandatory to connect that pink cable to the chassis, however, I did not see any sense in connecting that cable in the case of cranes with an electric power source, but I had no argument as if to validate that said procedure did not make sense. Thank you very much for your contribution Silan.
