Video Doorbell Pro 2 Transformer Polarity
Hi allBought the Doorbell Pro 2 with hardwired transformer, and I am nearly ready to fit it.I have installed the Ring Transformer in its own enclosure, I note its a DC output on the unit, however, no mention is made of connection polarity at the actual doorbell in any of the instructions, and I cannot see polarity marked on the doorbell either.Can anyone confirm if the polarity matters as I don't really want to blow up an expensive video doorbell by connecting it incorrectly.

This came with a specific AC-DC Ring branded DIN rail transformer - 220V AC --> 24V DC (https://en-uk.ring.com/products/din-rail-transformer-gen-2)Obviously, the doorbell is compatible with both AC and DC, however, I want to make sure its not polarity sensitive on DC!EDIT--I just found this statement on the installation instructions for the transformer that I didn't notice before:* Connect the doorbell wires to + & - (doorbell wires can go in either terminal).Which leads me to believe that the doorbell is polarity agnostic.

CHi @blademansw. For clarification, the Doorbell Pro 2 can be installed with an existing doorbell transformer within the range specified below, or the compatible Ring accessories below. **For connecting to an existing doorbell system:**- Hardwired transformer (16 to 24 VAC, 50/60Hz, 10VA to 40VA)**Compatible** **Ring accessories:**- DIN Rail Transformer (24Vdc, 420mA)- Plug-In Adapter (24Vdc, 500mA)Regarding the polarity, you are correct that the doorbell wires can go on either terminal as outlined in the instructions. Make sure the terminals are tightened properly with a screwdriver. If needed, you can reference the installation instructions [here](https://support.ring.com/hc/en-gb/articles/360054675132-Installing-Your-Video-Doorbell-Pro-2) as well.

Make sure you have the correct power supply. Wired Ring doorbells use 18v A/C power supplies, at least in the USA.
