5.1 Preparation
WARNING!
Incorrect installation of the drive can result in
serious injury!
− The drive must be installed free of any tension.
− The drive must not move on the shaft.
− The design and subsurface of all components must be
suitable for the forces encountered.
− Installation must only be carried out from a safe
standing position (e. g. scaffolding).
Incorrect installation of the drive can result in
damage to property!
To avoid damage to the drive and the door, the drive must
only be tted if
− the drive is undamaged,
− the ambient temperature is -20 ºC to +60ºC.,
− the altitude of the location does not exceed 1,000 m,
− a suitable protection type has been selected.
5.2 Push-on assembly
Damage due to improper installation of the drive!
To avoid damage to the drive and to the door, the drive
must be mounted on a console or a torque support bracket
so that it is vibration damped.
REFERENCE
The relevant instructions for the door must be observed
when tting the drive to the door.
Solid shaft
