I ran into an inconsistency with the i3 user guide that I downloaded from the shelly.cloud knowledge base: https://shelly.cloud/documents/user_guide/shelly_i3.pdf
In the downloaded document, the DC wiring diagram has a couple issues. I discovered them while trying to hook up some switches today while referring to the downloaded user's guide and it wasn't working properly.

|1) The L and N labels are swapped.|
2) The colors are mismatched (positive blue, negative red)
|L and N locations match the physical i3.|
Positive/negative colors are correct.
I'm going to open a ticket to report this, but currently the ticketing system is unavailable.
