Wind resistance classes
The awning meets Wind Resistance Class 2.
The awning must be retracted as from wind
force 5 (Wind Resistance Class 2).
The awning manufacturers must test their
products for wind resistance and declare the
correct wind resistance class. DIN EN 13561
defines corresponding wind resistance clas -
ses with their allocated wind forces accor-
ding to Beaufort. If no test has been perfor-
med and/or Wind Resistance Class 1 has not
been reached, the awning must be given
Wind Resistance Class 0.
The following table shows the wind resistan-
ce classes in accordance with DIN EN 13561
and their allocated wind forces according to
Beaufort.
Use of awnings in windy regions
When using motorised awnings in windy
regions or in regions with frequent power
cuts, it is recommended to use motors with
a manual emergency crank or emergency
power supply.
Motorised awnings without a manual emer-
gency crank or emergency power supply
cannot be retracted during a power cut and
could therefore be severely damaged or
destroyed!
