2.3. Ceiling installation
In case the unit must be installed on the ceiling, the minimum horizontal distance from the unit
to the license plate must be of 5 m and the angle between the unit and the floor must not exceed
30º.
The maximum height where the unit could be installed (h), can be calculated as
follows:
h=L·tanβ
where for a minimum horizontal distance of 5 m, we get h= 2.9 m.
