2 ground wires on a ceiling fan

Member is in Switzerland .

I'm installing a ceiling fan.

This black part will go against the ceiling.

And this is the top of the fan.

There's one short ground wire screwed directly to the metal tube that supports the fan and another ground wire that goes all the way to the motor.

I'm a bit puzzled by these two ground wires.

Could anyone let me know which one I will have to connect where?

This is primarily a North American forum. Not sure anyone is familiar with wiring practices in Switzerland.

Just tie all grounds together. The reason why there are multiple grounds are because some metal parts are insulated from each other by a rubber or plastic parts.

Ground wire screwed into the tube is grounding the metal tube. Ground wire running down the tube grounds the fan housing and motor. Ground wire on the mounting plate is grounding the plate.

The US model looks almost same except in the US terminal block is not used and ground wire is only on the tube. In the US wire nuts are used in a junction box. And I guess grounding tubing only is considered good enough in the US. Metal tubing is usually connected to the fan by a metal pin and 2 or 3 screws. That provides grounding to the fan housing.
But, I have seen separate grounding wire before.
