I am using ADE7858A for my application. ADE7858A is interfaced with an microcontroller over I2C protocol. I have connected AGND, DGND and neutral together. I was bit worried about these connections and have following questions:-

 

1.) Is it ok if I don't connect AGND and DGND together. 

2.) In case if anybody interchanges phase and neutral connection and it might lead to damage of all the components like microcontroller and other ic. How can i protect my circuit from wrong connection.

 

Thanks.
