Extra information for ...Max – size M
► Mounting of ...Max actuators
...Max actuators size M are equipped with a 16 × 16 mm (double square) shaft connection
by default. The form-fitting shaft connection is the most secure connection between
damper shaft and actuator because slipping or slipping through is avoided compared to
the force-fit clamp-connection.
The actuator will be connected firmly to the damper or fixed to a mounting bracket by
means of four screws M8 (scope of delivery).
For square damper shafts 12 × 12 mm or 14 × 14 mm reducing bushes are also available.
The actuators are axially symmetric developed. In case of spring return function the safety
position must be selected by turning the actuator to 180°.
Furthermore it is to be considered that the actuators have a total angle movement of
approx. 95° in order to realize a pretension on the control element (damper or the like).
Therefore the actuator sits tilted on the damper shaft.
► Mounting on air dampers
Form-fitted shaft connection – Mounting on square damper shaft
Mounting:
1. Affix tap holes M8 (in accordance with drill template) on the damper or to a
mounting bracket.
2. Adjust drive shaft of the actuator with the socket wrench that the drive stands
perpendicularly to the damper before plugging actuator onto the damper shaft.
3. Plug actuator onto damper shaft and fix diagonally with 2 screws.
4. Remove the socket wrench.
5. Pivot and tighten the remaining screws.

In order to adjust this and to induce pretension, the driving shaft has to be alined mechanically
over the hand-operated control socket "HV" when connecting to the damper shaft.
The socket wrench has to be turned counterclockwise when facing the actuator's "side R",
facing "side L" turn manual override clockwise.
Attention: Mount with appropriate safety precautions only!
!
▪ The drive shaft may only be mechanically adjusted either with the provided
socket wrench or the optional accessory "HV-MK" manual override (turn off
power supply). External force applied to the shaft can lead to mechanical damage
of the actuator !
▪ At the manual override counteracting forces occure when mounting spring return
actuators. Do NOT release manual override under spring tension!
4 screws M8 × 140 mm as well as a socket wrench are part of delivery.
For square damper shafts 12 × 12 mm or 14 × 14 mm reducing bushes
are available as optional accessories.
