All the basic requirements of the main installation
manual should apply to the alternative mounting
methods, unless otherwise speciied.
Design load and safety factors will be determined by
the racking suppliers or professional engineers. For
detailed information, please follow local structural
code or contact your professional structural
engineer.

· The mounting method has been qualiied by
Canadian Solar Inc. and certiied by VDE and CSA.
· Top or bottom clamping methods will vary and
are dependent on the mounting structures. Please
follow the mounting guidelines recommended by
the mounting system supplier.
· Each module must be securely fastened at a
minimum of four points on two opposite sides.
The clamps should be positioned according to
the authorized position ranges deined in table
A. Install and tighten the module clamps to the
mounting rails using the torque stated by the
mounting hardware manufacturer. M8X1.25-
Grade8.8 bolt and nut are used for this clamping
method. Tightening torques should be within
17~23 Nm (12.5~17.0 ft-lbs) for M8 coarse
thread bolts, depending on the bolt class. For
the bolt grade, the technical guideline from the
fastener suppliers need to be followed.Different
recommendations from speciic clamping
hardware suppliers should prevail. System
designer and installer are responsible for load
calculations and for proper design of support
structure.
· Canadian Solar Inc.’s warranty may be void in cases
where improper clamps or unsuitable installation
methods are found. When installing inter-modules
or end-type clamps, please take the following
measures into account:
Do not bend the module frame
Do not touch or cast shadows on the front glass
Do not damage the surface of the frame
Ensure the clamps overlap the module frame by
at least 5 mm (0.2 in)
Ensure the clamps overlap length is at least 40
mm (1.57 in)
Ensure the clamp’s thickness is at least 3 mm
· Clamp material should be anodized aluminum
alloy or stainless steel.
· 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 A, depending on the
coniguration and load.
· For conigurations where the mounting rails run
parallel to the frame, precautions should be taken
to ensure the bottom lange of the module frame
overlaps the rail by 15 mm (0.59 in) or more.
