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
61215
/
61730
testing; these have been evaluated by
REC’s internal testing process.
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.
5
).
If the panel is secured in zones with di
ff
erent load values, it is rated to the lowest load value only.

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.
