4. Assembly preparation
Foundation
Before mounting the tracking system a suitable foundation is necessary. A surface foundation for the
tracking system has to be constructed to assure the correct operation for the indicated maximum of
module surfaces (see fig. 4.1)
While setting mounting pole into foundation (1) take care of the exact adjust-
ment of cross holes into EAST – WEST direction!
To get the right adjustment use some helping material (see figure
hereunder).
During drying-procedure of foundation please use wooden boards to support mounting pole.
In case of installation on flat roofs, stability can be effected with clamping belts.

5.5. Mounting of solar modules
Each solar module is to be fastened with 4 pcs fixation clamps(12) at the
Centre rails (7). Please start with the following steps:
- Attach the fixation clamps on the module fixations
- Put in the screws M8 x 110 mm from the top into the drillings given at the
centre rails
- Connect the centre rails with connecting tubes (8), connection clamps (9)
as well as upper motor fixation (10).
- Fixation of solar modules
Before final tightening of screws please check easy swivelling feature. In case of
difficulties the adjustment of the hinges or rails could be not correct. The module
frame has to be aligned right-angled.
