PEAK 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.
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 di
ff
erent load values, it is rated to the lowest load value only.

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
a
ff
ecting the warranty. Loads marked with a
*
were not certified as part of IEC

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