This number depends on assembly, mounting, current values etc. Instructions: After choosing a pane dimension, you determine the maximum number of flaps per LZG rack. Then, based on the drive torque of the EWA power drive, you calculate the total number of possible flaps. > Glass 4 mm > Roof angle a = 22°–25° > Gutter height Tr = 150–180 mm > Gable height, roof height HG = 820–850 mm > Rack stroke = 650–670 mm > Revolutions = 19.7–20.3 (PAR 06, Chapter 3 )
