Different phases on inputs

[anonymous_1]

I have an existing setup with 3-phases. There are some inputs I would like to monitor, but they are connected to different phases of that system. Can I connect them to the Shelly inputs or must all three inputs of the Shelly Pro 3 be on the same phase?

 

Thanks.

The three inputs MUST be switched with ONE phase only!

Can I also use the neutral to switch the inputs? This being a three phase system, all phases share a neutral. So if I could connect the neutral to the input my problem would be solved as well.

Yes, indeed. The SW input are both activated by live and/or neutral potential.

To understand:

1. The switching inputs must be on one phase
2. However, three different phases (Input I1 - I3) can be switched

So the documentary!
