If you have a remote controlled shutter you will simply need to plug in the product to a standard three-pin plug socket. Some people like to have an external socket for this purpose; others like to feed the cable through the wall to an internal socket. Either is perfectly acceptable.
Hardwired motors will require the shutter to be wired to the provided switch then wired from the switch to the plug socket.
If you opt for the manual operation then you need to drill a 20mm hole through the wall and feed the pull cord through to the mechanism inside.
