Each module must be securely fastened at a minimum of 4 points on two opposite sides. The clamps should
be positioned according to the authorized position ranges defined in table C-1. Install and tighten the
module clamps to the mounting rails using the torque stated by the mounting hardware manufacturer.
System designer and installer are responsible for load calculations and for proper design of support
structure.
EDF ENR PWT warranty may be void in cases where improper clamps or unsuitable installation methods
are found. When installing inter-modules or end type clamps, take measures so as:
1.
Not to bend the module frame
2.
Not to touch or cast shadow on the front glass
3.
Not to damage the surface of the frame
4.
To ensure the clamps overlap the module frame
by at least 5 mm.
5.
To ensure the clamps overlap length is at least
40 mm.
Clamp material should be anodized aluminum alloy. Floating type clamps are not authorized.
Clamp positions are of crucial importance for the reliability of the installation, the clamp centerlines must
only be positioned within the ranges indicated in table C-1, depending on the configuration and load.
For configurations where the mounting rails run parallel to the clamps installation side, precautions should
be taken to ensure the module frame (C-shape) overlap the rail by 15mm or more.

Clamping
on short
side frame
Use 4 clamps on the short side, the allowed
range depends on the module type. Mounting
rails may run parallel or perpendicularly to the
short side frame
Use 4 clamps on the short side, the allowed
range depends on the module type. An additional
support bar should be placed below the module.
Mounting rails should run parallel to the short
side frame
