overvoltage protection of ADE7880 measuring inputs

I need to know how to protect the current and voltage sensing inputs against overvoltage on ADE7880.

The inputs have maximum rating at 2V but transils start at 3V.

We must protect current sensing inputs against overvoltage when there is overcurrent in the primary circuit of the current transformer (short circuit).

There is no information about protection in the datasheets and there is no protection on the evaluation board.


Or is there integrated protection in the ADE7880?


Thanks for help
