The earth wire (green/yellow) can be left in place or can be connected to a terminal block hidden behind the backplate.

The Wiser will fit on the existing backplate so, if you are installing the Wiser in the same place as the old ST9100, all you need to do is move the wire from terminal 4 to terminal 3, and the job is done.

Make sure you turn the electricity off while working on the backplate.
