Installation
Caution
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 accordance 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 fastening 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 securing 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 ob‐
jects 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 barrel, must be used
with these drives. After fastening the drive, the feather key must be secured from moving using the screw sup‐
plied.
