3.2.2 Assembly of structure onto aluminium
triangles:
The placement of profiles that support PV modules is performed using the
slotted holes the aluminium triangles have at the top part.
In order to assemble the profiles, DIN 933 M8 A2 bolts have to be
introduced in the profile slots as shown in the image and fastened to the
triangles in the correct position through DIN 6923 M8 A2 nuts.
The proper positions for profiles will be at the upper and intermediate
slotted holes as shown in the corresponding kit drawing.
NEEDED TOOLS AT THIS STEP ARE:
•
Open end wrench no 13 or torque wrench with socket no 13.

3.2.3 Junction between aluminium profiles:
The joint between two aluminium profiles that form the structure is
performed with an aluminium plate with 4 holes, using 4 DIN 933 M8 A2
bolts and 4 DIN 6923 M8 A2 nuts to secure them as shown in the image.
Firstly, the bolts are inserted loosely in the plate as displayed on the
image. Then, half of the plate is inserted at the end of the first profile,
assuring that two bolts are inserted at the bottom slot. Subsequently,
tighten these two bolts to fix the plate to the first profile.
Secondly, the end of the second profile will be inserted until it stops with
the first one, also guaranteeing that these two bolts are inserted at the
bottom slot. Finally, the proper torque setting to every fastener will be
given.
NEEDED TOOLS AT THIS STEP ARE:
•
Open end wrench no 13 or torque wrench with socket no 13.
