D. Assemble the clamp screws onto the motor support shaft and screw lightly into
position.
E. Mount the motor support shaft onto the profile of the actuator, ensuring the clamp
screws fit correctly into the profile socket, and make sure the socket is positioned
correctly into the base of the actuator (Fig. 6).
F. Keep louvres or sun screen closed and place the shaft on the wall vertical to the
frame, making sure that the axis of the actuator is parallel to the lever and
perpendicular to the connection pin. Check the shaft has been inserted into the base
of the actuator
G. Mark out the four holes for drilling for the screws for the motor support shaft.
H. Drill holes, insert the screws and fix the motor support shaft to the frame.
I. Tighten the clamp screws. Suggested tightening torque is 5÷7 Nm.
J. Turn on the actuator and carry out a complete test to check window opens and
closes correctly.

Assembly of more than one actuator with connection bar
SKY650 actuators can be used in tandem or series by means of a mechanical
connection bar. Movement is thus transmitted mechanically and uniformly and at the
same speed.
Two or more actuators can be mounted on the frame with one or more motors in
accordance with force requirements. The following diagram indicates position and
distance between centres to be used during mounting.

Assemble as follows:
A. Mark the assembly distance between centres for the two
actuators out onto the frame in accordance with the
measurements in the above table.
B. Place the support brackets of the actuator into position, mark
out the holes for drilling, drill the frame and mount the
brackets (see “Assembly for outward opening windows” for
details).
C. Place the front brackets into position, mark out the holes for
drilling, drill the frame and mount the front brackets (see
“Assembly for outward opening windows” for details).
D. Mount the actuators (see “Assembly for outward opening
windows” for details) – see Fig.7.
E. Mount the connection bar as follows:
•
Insert the connection bar first into one of the actuators, and then into the second
actuator. Make sure the bar protrudes at least 2 mm from each actuator (Fig. 7 bis).
•
Mount and screw the M8x14 mm flat headed screw (provided with connection
bar), into the two ends of the bar to prevent the bar from slipping out.
9. Electrical connections
The actuator comes with a 2 m long circa (±5%) lead which has been calculated in
accordance with safety rules.
In the event that the distance between the actuator and the control button should
exceed this length, the cable should be extended. See table on page 8 for conductor
section indications. For harness, please follow the these diagrams.
After connecting the electricity supply to the control button (bipolar with arrows if possible),
check that the up key function opens the window frame and the and down key function
closes it. In the event of incorrect function, invert the two wires marked light blue and
