MOUNTING EVPXXXXPK SERIES MODULES 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 module.
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 (Figure 17). If the panel is secured in zones with different load values, it is rated to the lowest load value only.
**Gap between the uppermost part of the installation surface(e.g. rooftop) and the lowest part of the panel (i.e. underside of panel frame)

Once a module is secured in each of the 4 zones (Figure 8), 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 UL 61730 testing; these have been
evaluated by internal testing process.
