I Mounting Wall
This centralized controller can be mounted on a wall with a thickness of 6–30 mm.
Since the maximum wall thickness for the centralized controller's mounting screw M4 × 30 8 is 17 mm, use screws of the
appropriate length for the wall thickness if the wall is between 17 mm and 30 mm thick.
(The best length for an M4 mounting screw is the wall thickness plus 13 mm.)
