Drive shaft
Depending on the door strength and the installation position, the drive shaft (2) included in the delivery must be adjusted to the
required functional length, in order to guarantee proper functioning of the locking system. The required length dimension W is
obtained from the distance L between the lock mounting plane and the input unit mounting plane + 20 mm immersion depth into
the input unit + 26.5 mm immersion depth into the lock (tol0/-2 mm, see Figure 32).
Shorten the drive shaft (2) only on the side
not
drilled (see Figure 33)!
To shorten it, the drive shaft (2) must be removed from the lock, since otherwise there will be a risk of damaging
the lock!
