Installation
Caution
During installation of the drive, access to the danger zone must be blocked off.
The drive has to be mounted on a vibration reducing mounting or torque supporting plate (in accordance
with the output of the drive) with adequate stability. Indirectly driven drives should not be mounted on a
vibrationreducingmounting.Thetighteningtorqueofthe4fasteningscrewsM8(8.8)forsecuringthe

this can result in the product or something in its vicinity being damaged. In the case of drives with a hollow
shaft diameter of 25.4 mm / 31.75 mm, only the feather key supplied may be used. After fastening the
drive, the feather key must be secured from moving using the screws supplied.
When installing the drive, it must be ensured that the drive is protected against soiling (e.g., drilling dust). Before mounting
the drive on the door shaft, the latter must be lubricated in the drive area.
Emergency manual operation
Emergency manual operation is only intended for starting up the drive, maintenance work and emergency operation in order
to open or close the door in the event of a short-term power failure. Emergency manual operation is only intended for short
term manual operation.
Attention
Before emergency manual operation is used, the door system must be disconnected from the power sup-
ply. Emergency manual operation is only allowed with the motor turned off, via hand crank, and can only
be carried out by the service technician or instructed personnel.
Emergency manual operation is not intended for long-term use (e.g., from starting up the drive to
continuous power supply).
Doors with counterweights must be set in such a way so that they are completely counterweighted in all
positions. If the door is not balanced properly, the manual force required is increased and the service life
of the emergency operation mechanism is reduced.
Note(appliestoA80-A280)
The door must not be moved beyond the limit positions as otherwise a safety limit switch (S1F/S2F) is
activated. Electrical operation of the door system is only then possible when the safety limit switch (S1F/
S2F) is “released” via emergency manual operation.
4 dierent systems are available for emergency manual operation:
• Crank handle (HK)
• Light chain (LK)
• Disconnecting clutch (AK)
