CAUTION
The center point of each clamp and the minimum grip length must be fully located in the same clamping zones to be rated to that load (fig. 6).
If the panel is secured in zones with different load values, it is rated to the lowest load value only.

Installations with a clearance gap between the uppermost part of the roof and lowest part of the panel (i.e., frame) with a clearance
gap of <20 mm are not permitted.
Once a module is secured in each of the 4 zones (fig. 2), additional clamps, i.e., ≥5, may be freely located on panel frame without
affecting the warranty. Loads marked with a

REC’s internal testing process.
