Installation and electrical connection
3.1. Installation of the motor into a shaft
1. Crown and coupling adapter need to be determined according to the size of the shaft
(picture 1).
2. Push the crown adapter over the shaft and position it precisely on the motor head.
3. Slide the coupling and plug-in the coupling locking device (picture 2).
Picture 1: Examples for different shaft sizes
Picture 2: Coupling locking device*
* For drives of series 3 the coupling will be secured with a ring (security ring according to
DIN 471-20x1,20 FST, article number 940516). To fix the security ring a special security ring
pliers for shafts with eyelet size < 2 mm is necessary!
4. Push the motor into the shaft in a positive-locking way. The motor must not be subject to
any impacts. Crown and coupling adapters must not have any play inside the shaft.
5. Where required, secure the motor axially, e.g. by screwing the shaft to the coupling
adapter. Do not drill holes into the motor area!
6. Attach the shaft with the motor and the shaft cap in the bearings. Do not bend the motor
cable and aerial and place them so that neither the aerial nor the motor cable cannot be
damaged. Do not place the aerial parallel to the motor cable. The aerial must not be short-
ened or extended. To keep water from getting into the motor, place the motor line in a
bend direction downwards, so that any water can drip off.
7. Attach the curtain to the shaft.
