The panel mounting systems must be installed only on buildings that have been formally validated for structural
integrity, and which have been considered capable of supporting the additional weight of the panels and mounting
systems, by a certified building specialist or engineer.
The supplier of the mounting system must take into account the galvanic corrosion which may appear between the
aluminium frame of the panels and the mounting system or the grounding parts if they are made of different metals.
The module is only certified when its original frame is completely intact. Do not remove or modify the module frame
in any way. Drilling additional mounting holes is likely to damage the module and reduce the strength of the frame,
and thus is not allowed.
The use of flanges and fasteners with additional grounding bolts or grounding connectors shall be in accordance with
this safety and installation instruction manual and according to the conditions in section 4.3.
The modules can be installed according to the following methods:
1.
Frame holes:
attach the module to the structure using the factory-made mounting holes. It is recommended
to use four M8x16 mm stainless steel screws with bolts, washers and lock washers for each module. The
maximum tightening torque of the bolts is 24 N.m.
2.
Callipers or clamps:
the brackets can be mounted on the longitudinal (longest side) or lateral (shortest side)
side of the module. The areas allocated to these clamps are specified in chapter 3.2 below. Installers must
ensure that the resistance of the clamps is sufficient given the maximum pressure to which the module can
be exposed. The clamps are not supplied by DualSun.
It is important to make sure that the clamping brackets do not distort the top of the aluminium frame of
the DualSun panel, this may weaken or even break the glass.
The tightening torque of the clamps must not exceed 24 N. m.
The compatibility of the mounting system with the modules must be assessed before any installation,
especially when the system does not use brackets or clamps.
