Safety notes
!
• The damper actuator is not allowed to be used outside the specified field of applica tion,
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.
• The cable must not be removed from the device.
• When calculating the required torque, the specifications supplied by the damper
manufacturers (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.
