MOUNTING EVPVXXXH AND EVPVXXXHK SERIES MODULES WITH CONTINOUS RAILS PARALLEL
TO LONG SIDE OF THE MODULE
A continous rail (or other support structure) spans the complete underside of the 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 13).
If the panel is secured in zones with different load values, it is rated to the lowest load value only.
