MOUNTING METHODS: CLAMPING WITH RAILS PARALLEL TO THE SHORT SIDE

The rails must run underneath the panel to provide support to the frame. Where the rails are positioned parallel to the short side of the panel as in 

fig. 2, the clamping zones shown in fig. 3 are to be followed:

•  Each panel must be clamped in a minimum of four separate zones, with one clamping point in each quarter of the panel (fig. 3).
•  The distance between the end clamp and the end of the rail must be a minimum of 25 mm.
•  Follow the clamp manufacturer’s instructions to install the clamps, including the recommended applied torque.
•  The position of the rails must ensure that the minimum grip length of the clamp and the central point of the fixation, e.g., the bolt, is fully within 

the required clamping zone.

CAUTION

The minimum grip length of each clamp and its center point must be fully located in the same color zone to be rated to that load value (fig. 4). If 

the panel is secured in two different zones, it is rated to the lower load value only.

NOTE

If required, any further clamps, i.e., ≥5, may be clamped elsewhere on the panel, including in the red zone without affecting the warranty.
