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.

INSTALLATION OF REC ALPHA SERIES PANELS
MOUNTING REC ALPHA SERIES PANELS WITH CONTINOUS RAILS PARALLEL TO SHORT SIDE OF THE PANEL
A continous rail (or other support structure) spans the complete underside of the panel.

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 / UL testing; these have been evaluated by REC’s
internal testing process.
