installation regulations must be complied during installation.
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.
Cables must not be removed from the device.
To calculate the torque required, the specifications supplied by the damper manufacturers
concerning the cross-section, the design, the installation situation and the ventilation
conditions must be observed.
The device contains electrical and electronic components and must not be disposed of as
household refuse. All locally valid regulations and requirements must be observed.
Product features
Simple direct mounting on the damper shaft with a universal shaft clamp, supplied with an anti-
rotation device to prevent the actuator from rotating.
