H. Use an appropriate size of drill head for perforation, insert the screws and fix the
motor support bracket to the casement.
I.
Tighten the clamp screws. Suggested tightening torque is 5÷7 Nm.
J. The actuator can now be powered up for a complete trial of opening and closing
procedures.
8.6. Assembly in tandem with connection bar (1 – actuator, 2 – bar, 3 – rod)
SKY450 actuators can be connected in tandem with a
mechanical connection bar. Two pressure points can be
obtained using one single motor.
The movement of the motorised actuator (1) is connected
to the rod (3) (no motor) mechanically for the window to
move evenly at a steady speed.
The illustration to the side indicates the layout and inter-
axes that should be used during assembly. The length of
the connection bar (2) is expressed by “

(Interaxis for
actuators)

mm.

For assembly, proceed as follows:
A. Trace the interaxis for assembly for the two actuators onto the frame according to
the dimensions in the above table.
B. Position and assemble the support frames for the actuator
(see detailed explanation
in the paragraph entitled “assembly for top hung windows opening outwards”)
.
C. Position the brackets onto the sash, trace in the points for the openings, perforate
the window frame and assemble the brackets onto the sash.
D. Assemble the motorised actuator (1), inserting the clamp screws slightly into the
profile and lightly fix the screws into position. Check the rack is in “stroke-end return”
(rack in full return position)
position.
E. Take the rod (3) in one hand and use the other hand to insert the connection bar
into the opening provided (2). Insert the other end of the connection bar into the
opening on the motorised actuator (1).
F. Assemble the rod (3), inserting the clamp screws slightly into the profile and lightly
fix the screws into position. Check the rack is aligned with that of the motorised
actuator.
G. Loosen the clamp screws and place the eyebolt heads into the brackets assembled
onto the sash. At each point, insert the M6x25 screw into both bracket and eyebolt
and fix the nut in position using two 10 mm keys.

H. Manually move the actuator along its axis to close the window correctly and firmly
against the seals. Tighten the clamp screws right in and align the actuator with the
casement.
I. The actuator can then be powered up for a complete trial of opening and closure.
After closure is complete, check that the window is completely shut and check
pressure on the seals.
J. The stroke-end of the actuator is automatic. The appliance exerts a traction force to
ensure perfect pressure against seals even for large dimension windows.

Electrical connections
Appliances are equipped with cable

, and is 1 m (±5%)
long. 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
BLACK
and
BROWN
.
For harness, please follow the
diagram by the side.
10. Stroke-end
10.1. Stroke-end at opening and closure
The stroke-end at opening and closure is automatic, electronic and cannot be
programmed. The actuator is stopped by the absorption of power encountered when
the window is completely open or completely closed.
10.2. Stroke adjustment where required
Strokes shorter than the stroke produced during manufacture can be created at will to
suit the protrusion length of the rod.
This operation should be performed on the bench using the appropriate equipment by
qualified technical personnel with the ability to perform each operation with maximum
diligence and safety.
Work phases are as follows:
100-240V~ 50/60Hz
