• The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or any other form of air transport.
• Assembly must be carried out by trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.
• The device may only be opened at the manufacturer‘s site. It does not contain any parts that
can be replaced or repaired by the user.
• When calculating the required torque, the specifications supplied by the damper manufactur­
ers (cross section, design, installation site), and the air flow conditions must be observed.

• The device contains electrical and electronic components and is not allowed to be disposed
of as household refuse. All locally valid regulations and requirements must be observed.
Product features
Simple direct mounting
Manual override
The hollow spindle of the actuator is mounted directly on the damper spindle ( 8 mm) with
a positive-fit connection. The actuator is then secured with the anti-rotation strap supplied, to
prevent it from rotating.
Manual override with magnet possible (the gear is disengaged as long as the magnet adheres to
the symbol . The magnet for gear disengagement is integrated in the position indicator.
U
Adjustable angle of rotation
High functional reliability
Adjustable angle of rotation with mechanical end stops.
The actuator is overload-proof, requires no limit switches and automatically stops when the end
stop is reached.
