5a/5b), and achieve the 5.4 kPa load
rating.
•
In horizontal configuration, fixing the
modules by blocking them at the 4
mounting holes will guarantee the
characteristics regarding the static loads as
certified.
•
When clamping the modules in horizontal
configuration on a support structure, the
following rules have to be applied in order
to maintain the resistance against static
loads as certified:
o
If the bars or rails are in vertical
direction, they have to be placed
nearby the corner holes or in any case
a spacing of 800-941 mm between the
bars has to be maintained in order to
achieve the 5.4 kPa load rating (Fig.
5a/5b).
o
If the bars or rails are in horizontal
direction, they have to be placed with
a spacing of 500-750 mm in order to
achieve the UL specified 2.4 kPa load
rating (Fig. 5a/5b).
•
The modules can also be fixed by placing
them with their frame on a structure that
is supporting the two sides of the frame
over their whole length. In this case, the
position of the mounting clamps must be in
accordance with the above mentioned
spacings (800-941 mm and 500-750 mm
respectively) – refer also to Fig. 5a/5b.
