Determine the entry opening(s) in the back box (3):
- For recess-mounted cable entry: Breakout point in back box (3).

Installation

Mount the back box (3) at the desired height on a flat surface, following country-specific regulations.
Pull the cable through the entry opening into the back box (3).
