Installation
Caution
Before installing the drive, the driven part must be checked with regard to its mechanical
condition and to ensure smooth opening and closing.
During installation of the drive, access to the danger zone must be blocked off.
The drive must be properly mounted on a mounting or torque supporting plate (in accord-
ance with the output of the drive) with adequate stability.
In the case of directly operated door systems, the drive must be mounted using 4 fastening
screws M8 (8.8) on a vibration reducing mounting.
In the case of indirectly operated door systems, the drive must be mounted using 4 fasten-
ing screws M8 (8.8), however should not be mounted on a vibration reducing mounting.
The maximum distance between the drive and chain wheel gearing must not exceed 50
mm.
Assuming a screw-in depth of 10 mm, the tightening torque of the fastening screws for se-
curing the drive must be at least 20 Nm and no more than 25 Nm. Failure to observe this
may result in damage to the product or objects in the immediate vicinity.
Once the sectional door has been mounted and properly counterweighted, the door must be counterweighted in every position.
The correct counterweight is manually adjusted by opening and closing the door.
When installing the drive, always ensure that the drive is protected against soiling (e.g., drilling dust).
Before mounting the sectional door drive on the door shaft, the latter must be lubricated in the drive area.
Attention
Only one of the two feather keys supplied, which is fitted according to the form of the bar-
rel, must be used with these drives. After fastening the drive, the feather key must be se-
cured from moving using the screw supplied.

Emergency manual operation
Emergency manual operation is only intended for commissioning 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 solely intended for manual op-
eration.
Caution
Before emergency manual operation is used, the door system must be safely disconnected
from the power supply. Emergency manual operation (HK) is only allowed with the motor
turned off, via hand crank, and can only be carried out by the service technician or instruc-
ted personnel. Emergency manual operation (LK) is also only allowed with the motor
turned off.
Attention
Emergency manual operation is not intended for long-term use (e.g., from commissioning
of the drive to continuous power supply).
Doors with counterweights must be set in such a way that they are fully counterweighted in
all positions. If the door is not counterweighted properly, the manual force required is in-
creased and the service life of the emergency manual operation mechanism is reduced.
