D - There is a 20mm zone at 388-408mm from the corner where mounting is not
allowed due to the module stacking pin feature. Not applicable for all P19 Series, all P3
Series, 96 cells residential modules, all 104 cells and MAX5 modules.
1) No part of the module clamp may extend beyond this area.
Figure 3: Mounting Configurations
Configurations 1 and 2 show mounting with rail support, 3 and 4 show
mounting without rail support. In “With Rail Support” the rails
becomes conventional or rails transverse while “Without Rail
Support” becomes end mounted in long or short side. In the case
when the glass deflects it would not deflect in the rails for additional
support.

without rail support underneath the module. Refer to Configuration 3
