6. Determine the position of the second row of mounting clamps. Mind keeping 15 mm space to the upper edge of
the module.
TIP
It must be possible, where necessary (e.g. repair work), to be able to remove the modules from the row!
Fasten further rows of mounting clamps leaving space X (15 mm) to the modules (cf. image 4-11).
When removing, slide the modules upwards until they are free of the lower clamps.

7. Fasten the second row of mounting clamps to the rafter and test for stability.
TIP
The system measurement „R space between the mounting clamps“ (cf. image 4-1) is crucial for the correct
installation of the module array and for the resultant optical appearance.
The vertical space between the mounting clamps is a system measurement of the module array and should
thus be adhered to in the rows.
Adjustment of the row space for several rows by respective multiplication of the space measure.
