4.
As shown in the above installation method, slide bolts through groove on the supporting bars next to the
locations where the clamps are to be fastened. Clamp position is very important, the module must be clamped only
on the long edge, Fig. a "D" dimension the centerline of clamps to module edge. Number of clamps, clamps positions
match relevant mechanical load, please refer to Table 2 and tab 3.
