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. ).
If the panel is secured in zones with different load values, it is rated to the lowest load value only.

Once a module is secured in each of the  zones (fig. ), additional clamps, i.e., ≥, may be freely located on panel frame without affecting
the warranty. Loads marked with a * were not certified as part of IEC / testing; these have been evaluated by REC’s internal
testing process.
