SC-PSA Coplanar mounting system with PSA-A
“Winged aluminium profile”
Read these installation instructions before starting installation and familiarise yourself with the system component.
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.
A. Plan view of SC-PSD system with horizontal module orientation (landscape type).
The type of fixing system and the location of its installation points shall be adapted to the needs of the supporting structures
and at the same time to the needs of the roofs where they must be installed.

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 profiles
B. Place the butylene tape on the high areas of the ribs where the PSA-A profiles are to be placed
Ref. FTA_GS_M_SC-PSA-en Rev: 0 23/06/23 7of 10
SC-PSA INSTALLATION MANUAL
C. Pre-install the PSA-A profiles by sticking the base onto the butylene tape and fix them with the thin sheet screws.
For the installation of the thin sheet screws use an electric screwdriver equipped with hexagon socket SW-8, an
installation speed of 1800 rpm is recommended

E. Fix the PSA-UN joint to the first PSA-A profile by installing 2 self-drilling stainless steel screws ABEI5519. The screws
must be installed in the lower 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.
F. Insert the free end of the PSA-UN connector into the second PSA-A profile.
Option 1 if a rigid connection is required: Insert the protruding part of the PSA-UN connection into the second
PSA-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 first profile.

G. Option 2, If a connection acting as an expansion joint is required: Insert the protruding part of the PSA-A joint
PSA-UN into the second PSE-C profile, leaving a gap between the ends of the two profiles of between 4 and 6
mm, 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

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.

SC-PSA INSTALLATION MANUAL
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.
