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 brown in the case of 24V
motors and invert the two wires marked black
and brown for 110-230V~ motors.
WARNING:
after every limit switch or electronic protection device function the
rack will back track for around 2 mm in the opposite direction. This is quite
normal, and has been designed to release tension on mechanical parts and
allow complete weather proofing to enhance durability of mechanical parts.
10. Limit switches
10.1.
Stroke-end at opening and closure
The limit switch at opening / closure is automatic, electronically operated and cannot be
programmed. The actuator stops when the charge is absorbed when the window is
completely open / closed.
10.2.
Stroke adjustment where required
Factory settings for track lengths can be shortened to regulate how much of the rod
protrudes. This operation must be carried out at the workbench with proper equipment
by technical personnel qualified to operate with maximum care and safety.
Procedure:
1. Remove the four screws on the front head of the SKY650 actuator.
2. Extract the head and rod from the body of the actuator.
3. Unscrew the two screws locking the two limit switch block pieces.
4. Move the rubber stopper and block to the required position.
5. Screw the two screws used for fixing the block into position back in again.
6. Re mount everything back onto the body of the actuator.
7. Screw in the four screws on the front head and check the settings for the new
track run.
11. Checking for correct assembly
Check that the frame has closed completely, even at the corners, and check there
are no obstacles caused by assembly in the wrong position.
Make sure the actuator is aligned with the axis of the window at 90° to the window
itself, otherwise the rack will exert incorrect pressure on the rod and consume more
voltage.
Check the lead is not too tight, as this could damage the actuator during rotation,
opening and closing of the window.
Check all screws and nuts have been properly tightened.
