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. 8).
If the panel is secured in zones with different load values, it is rated to the lowest load value only.

MOUNTING REC ALPHA PURE-R SERIES PANELS WITH SHORT RAILS
A short rail (or other short support structure) has a minimum length of 25 mm and does not span the complete underside of a panel.

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
*
were not certified as part of IEC 61215/61730
testing; these have been evaluated by REC’s internal testing process.
