6_ Join the 1-metre extension to the track with its joint (fig. 21).
7_ Pass one end of the belt through the head section, as shown in
fig. 22, and fix it to the joint with the screws and washers already
present (fig. 23). Take care to ensure the correct position of the
belt: it must be with the teeth facing inwards, straight without any
twists.
8_ Assemble the gear unit as shown in figure 24. This operation re-
quires some strength; use a rubber mallet if required.
9_ Pass the free end of the belt through the carriage, to the gear of
the chain tensioner and then again through the carriage to the
joint to establish the correct length. Take care to ensure the cor-
rect position of the belt: it must be with the teeth facing inwards,
straight without any twists.
10_ Cut the belt to the set length and fix to the joint by means of the
screws and washers already present (A fig. 25).
11_ Slide the belt until it is locked on the drive carriage (B fig. 25).
12_ Tension the belt by means of the nut (A fig. 26) until it is suffi-
ciently taut.
If the chain/belt is tensioned excessively, the motor will
undergo excessive stress with a consequent increase in
current absorption.
3.3_ Fixing the gearmotor to the guide
1_ Join the gearmotor with the head of the guide, then secure by
means of the 4 screws supplied as shown in figure 27.
2_ The motor can be rotated to three different positions, as shown
in figure 6.
3.4_ Fixing the gearmotor to the ceiling
1
_ In observance of positions A and B in figure 6, trace the two fixing
points of the rear guide bracket at the centre of the door. De-
pending on the type of material, the front bracket can be secure
by means of stud bolts, plugs or screws.
2_ After drilling holes at the envisaged points, leaving the gearmotor
on the ground, lift the guide from the front section and secure it
with two screws, plugs or stud bolts depending on the mounting
surface.
3_ Lift the sliding guide so that the rear attachment reaches the
same level as the front attachment, or to the same angle as the
horizontal track of the door (A fig. 28).
4_ Measure the distance between the ceiling and interaxis of the
gear unit fixing holes (B fig. 28).
5_ Bend the brackets supplied to the set measurement (measure
from the centre of the first slot on the bracket).
6_ Fit the brackets on the gear unit and reposition the sliding guide
(fig. 29).
7_ Mark the rear attachment fixing points on the ceiling (taking care
to protect the sliding guide).
Complete guide installation.
8_ Three-sections track: repeat points 3_ to 7_ for the fixing at guide
center
9_ For heavy doors or doors not running smoothly, the optional P-
100BINSUPP accessory allows a second ceiling fixing point (fig. 3).
10_ Assemble the door fixing bracket as shown in fig. 30.
11_ With the door closed, pull the cord to release the carriage as
shown in figure 31.
12_ Slide the carriage until the leaf attachment bracket is on the up-
per edge of the door, exactly perpendicular to the guide. Then fix
the leaf attachment bracket with stud bolts or screws as shown
in figure 32. Use stud bolts or screws suited to the material of the
leaf, checking that it is suitable to withstand all the force required
to open and close the door.
13_ Loosen the screws of the mechanical stops, then move it in front
of the carriage, as shown on figure 33. Firmly push the carriage in
the closing direction and, once reached the position, tighten the
screws (A) fully down.
14_ For opening phase, use any available mechanical stop, both the
door one and the complete automation track are equally fine.
15_ Attempt to move the door manually. Ensure that the carriage
slides freely, without friction on the guide, and that manual ma-
noeuvres are smooth without requiring particular effort.
3.5_ Installation of various devices
To install the other devices envisaged, refer to the
relevant instructions. Check in figure 2 the devices that can be con-
nected to T-SKY.

3.7_ Electrical connections

All electrical connections must be made withthe system
disconnected from the power supply.
1_ To open the protection cover and access the electronic control
unit of T-SKY, press on the side of the cover and turn the panel
door as shown in fig. 35.
2_ Route the connection cables to the various devices through the
cable clamps, leaving a length 20÷30cm more than necessary.
See para. 2.2 for the type of cables and figure 3 for connections.
3_ Make the connections as shown in the diagram in figure 36. Ter-
minals are removable to facilitate connections.
3.8_ Connecting to the power supply
For electric power supply of T-SKY simply connect the 230 Vac line to
the transformer safety fuse holder (A fig. 36).
T-SKY must be connected to the power mains by skilled
and qualified personnel, in possession of all requirements
for full compliance with all legal provisions, standards and
regulations.
The electric power line must be protectedagainst short
circuits and dispersion to earth; a device must be fitted to
enable shutoff of the power supply during installation or
maintenance of T-SKY.
