Important! Do not use fitted carrier rails as step ladders!
Figure 90: Butt connectors for type TF50 carrier rails
Important!
Ensure that all T-head screws and hammer nuts have engaged with the rail so they are completely
inserted.
Note:

Interlocking has been provided on roof hooks and type e.g. TF50+ carrier rails to compensate for
differences in height on uneven roofs.

Any carrier rails installed above each other must be in parallel. For this purpose, align the bottom
carrier rail horizontally first.

The ends of the rows must be aligned at an exact right angle (90°) to the bottom rail, as otherwise it
will not be possible to align the joints between the modules.

Once the carrier rails have been aligned, re-tighten IBC SOLAR AG screws to the corresponding
tightening torque and re-check.
