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 GP-XS aluminium profiles in the correct position for the installation of the panels.
B. Fix the position by using a DIN 6921 M8x20 bolt and TU-RX A2 nut. Tighten to a maximum torque of 15 Nm using a
SW-13 hexagon spanner.

STEP 5.- Longitudinal connection between guides
A. Assemble the EMP-XS joint by inserting half of the length into one of the two GP-XS guides.
B. Fix the EMP-XS joint to the first GP-XS guide by installing 2 screws DIN 603 (M8x20) and nuts DIN 6923 M8, at a
distance between 50 and 70mm from the end of the guide. Use a SW-13 hexagon spanner to tighten to a
maximum torque of 15 Nm.

C. Insert the free end of the EMP-XS connector into the second GP-XS guide.
Option 1, if a rigid connection is required: Insert the protruding part of the EMP-XS connection into the second
guide GP-XS until it butts against the first guide, and then fix the connection to this second guide by installing
2 DIN 603 screws (M8x20) and DIN 6923 M8 nuts, as previously carried out on the first guide.
Option 2, if a connection acting as an expansion joint is required: Insert the protruding part of the connection
EMP-XS into the second guide GP-XS leaving a gap between the ends of both guides between 4 and 6 mm, in
this case the screws are not installed to allow longitudinal displacements between the two guides.
Is recommended for this type of connection a maximum distance to the nearest fixing point
of 300 mm

PASO 6.- Pre-installation of clamps on the guides
To mount the clamp on the guides, the following steps are necessary:
1. Place the clamp in the guide
with the lower nut parallel to
the guide.
2. To fix the clamp to the guide,
the lower nut must be turned
perpendicular to the guide 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 an end clamp.
4. To fix the inserted elements
it is necessary to turn the screw
until they meet the guide.
Check that the lower nut
remains perpendicular to the
guide.
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.
