Limits Of Use In Relation To Wind - FAAC B680H Operating Instructions Manual

 4 Limits of use in relation to wind
The tables indicate the maximum permitted wind
force (Beaufort scale) for the B680H beam in relation
to its length.
Winds stronger than those permitted could affect the
operation of the B680H.
It is the responsibility of the installer to assess the im-
pact of the wind on all components of the structure in
order to calculate the maximum permitted wind force
for the automation.
