shelly plus 2pm and Busch-Jaeger 2000 Schalter

Hey!
I want to connect these wires to the Shelly Plus 2PM. Since the Shelly has one Line In and one Line Out, and I have two brown L wires connected to this Busch-Jaeger 2000 Schalter,
I'm seeking suggestions how to connect to Shelly Plus 2pm or whether I should use a Wago connector for these two lines and use just one as the input to the Shelly?

Zitat von Devil

The Shelly Plus 2PM has two terminals for L which are also bridged. However, I would always prefer the Wago as we don't know what load will follow.

That means this in theory should work?

1L and 2L -> 3x wago -> 3rd wire from wago -> Shelly first L terminal
Second L terminal -> Busch-Jaeger 2000 Schalter?
