The additional distance Z
SM
is always required. Its size depends on the biggest radius R
G
from the safety
sensor mirror's rotary axis to the protective field boundary without Z
Tot
. The position of the rotary mirror axis
depends on the installation situation.
The additional distance Z
F
is required if the vehicle does not have enough free floor space H
F
and there is
therefore no space under the vehicle or the safety sensor for the tips of the feet. You determine the addi
-
tional distance Z
F
according to the following diagram:
