Remove the internal protection covering the terminals by unscrewing the screw (Fig.2 C) and turning the cover upwards. Attach the base to the wall, using the horizontal (Fig.2 A-A) or diagonal distance (Fig.2 B-B).

Insert the cables through the opening at the bottom and connect them to the terminal board (Fig.4) then replace the internal cover and tighten the screw (Fig.2 C).

To close the device, proceed as before but reversing the sequence of operations: match the upper sides of the two parts (Fig.1 C) then turn the front panel downwards (Fig.1 B) until the lower hook clicks (Fig.1 A) on the base.
