Safety notes
!
• The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or in any other airborne means of transport.
• It may only be installed by suitably trained personnel.
All applicable legal or institutional installation regulations must be complied with.
• The cover of the protective housing may be opened for adjustment and servicing. When it is
closed afterwards, the housing must seal tight (see installation instructions).
• The device on the inside may only be opened up in the factory. It does not contain any parts
that can be replaced or repaired by the user.
• The cable must not be removed from the device.
• 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.
