concrete
Read these installation instructions before starting installation and familiarise yourself with the system components.
Installation must only be carried out by qualified and experienced personnel.
Installation guidelines:
Ensure that the roof construction is suitable for the introduction of forces at the fixing points and their
subsequent transmission. The building must be able to safely receive the additional loads.
A structural calculation must be carried out based on the local conditions at the installation site.
The planning of the layout of the fixing points must be adapted to the requirements of the system and the
roof.
To compensate for thermal expansion, include a spacing every 12m when planning the PV system.
The solar modules must be installed according to the manufacturer's instructions.
Follow your local building regulations.
Make sure to work in accordance with the health and safety regulations in force in your region, during
installation and during roof work.
Do not use the system or fixings as stairs.

INSTALLATION PROCESS
STEP 1.- Consult installation drawing
Consult the installation drawing on the roof, where the distribution of the modules is defined as well as the structures that
support them and their fixing points.

STEP 2.- Perform layout on the roof
Lay out on the roof the fixing points of each structure, checking the viability of the installation of each one depending on
the chosen fixing system and the characteristics of the roof.
STEP 3.- Installation of the triangles
Install the adjustable aluminium triangles and fix them on the deck at the agreed points with the help of the THE concrete
screw. For the installation of THE screws an electric screwdriver equipped with hexagon socket SW-10 is required, an
installation speed of 1800 rpm is recommended.

STEP 4.- Installation of the profiles on the triangles
A. Position the PSE-A aluminium profiles in the correct position for the installation of the panels.
B. Secure the position using the KFS-FL connector, two of them, one on each side of the PSE-A profile. Tighten to a
maximum torque of 15 Nm using a SW-13 hexagon spanner. The KFS-FL connector has a notch on the rear side to
aid assembly and coupling to the PSE-A profile.

STEP 5.- Longitudinal connection between profiles
A. Assemble the PSE-UN joint by inserting half of the length into one of the two PSE-A profiles.
B. Fix the PSE-UN joint to the first PSE-A profile by installing 2 self-drilling stainless steel screws ABEI5519. The screws
must be installed in the lower lateral part of the profile, at a distance between 50 and 70mm from the end of the
profile. For the installation of the ABEI5519 screws an electric screwdriver equipped with hexagon socket SW-8 is
required, an installation speed of 1800 rpm is recommended.

C. Insert the free end of the PSE-UN connector into the second PSE-A profile.
Option 1, if a rigid connection is required: Insert the protruding part of the PSE-UN connection into the second
PSE-A profile until it butts against the first profile, and then fix the connection to this second profile by installing
2 self-drilling stainless steel screws ABEI5519, as previously carried out on the fist profile.
Option 2, If a connection acting as an expansion joint is required: Insert the protruding part of the PSE-A joint
PSE-CUN into the second PSE-A profile, leaving a gap between the ends of the two profiles of between 4 and
6mm, in this case the screws are not installed to allow longitudinal displacements between the two profiles.
Is recommended for this type of connection a maximum distance to the nearest fixing point of
300 mm

STEP 6.- Pre-installation of clamps on the profiles
To mount the clamp on the profiles, the following steps are necessary:
1. Place the clamp in the
profile with the lower nut
parallel to the profile.
2.To fix the clamp to the profile,
the lower nut must be turned
perpendicular to the profile by
means of the screw, the screw
head is pressed down and
turned. The nut has a serrated
rail to secure the fixing.
3. Insert the corresponding
elements, two panels in the
case of an intermediate
clamp, or a panel and a
gauge in the case of a lateral
clamp.
4. To fix the inserted elements it is
necessary to turn the screw until they
meet the profile. Check that the lower
nut remains perpendicular to the
profile.
Type of clamp depending on its position:
A. Intermediate clamp
The intermediate clamp is used when passing from one module to another within the same row, fixing both
panels to the structure. This assembly is carried out by means of the screw included in the clamp. A tightening
torque of 14 Nm must be applied.

B. Lateral clamp
Prepare 4 KFRSC3050 quick fixing clamps to be mounted at the ends of each row of panels. Each of these clamps
is fitted with a GM-A gauge, mounted as shown in the figure:
The chosen gauge size must be equal to the frame height of the solar panels to be installed.
