Notes
• To guarantee IP66 protection, the device must
be mounted on the rear of the damper housing
without a gap.
• If the device is mounted on the front of the
damper housing (i.e. turned 180° ), it only has
IP54 protection.

• 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 mechanical end stops for restricting the angle of rotation are only allowed to be removed
for adjustment purposes. It is essential for them to be in place during operation.
