The BUS cable must protrude 20 to 30cm out of the wall to allow
installation. For securing to a wall we recommend using a flush
box, which can hold this part of the BUS cable. Make sure that
the screws supporting the flush box are arranged either vertically
or horizontally opposite one another. The chapter "Installation
options" describes installation without a flush box.
