*Alternate Mounting Method – bolt mounting method using the 12 provided mounting
holes in the frame with a torque of 16~20 N*m. The following stainless steel
mounting hardware should be included in the installation instructions.

2.3.2 Mounting with Clamps
The module clamps should not come into contact with the front glass and must not deform
the frame. Be sure to avoid shading effects from the module clamps. The module frame is
not to be modified under any circumstances. When choosing this type of mounting
method, please be sure to use at least four clamps on each module, two clamps should be
attached on each long side of the module. The applied torque value should be big enough to
mount the modules steadily (Please consult with the clamp or racking supplier for the
specific torque value). Please find detailed mounting information in the below
illustration. The mounting zone is greater than J and less than K. Figure 4 shows how a
clamp should be mounted to the module frame.
When installing modules using clamps on the long side of the frame, the applicable product
types and installation locations are shown in figure 5 and table 4.
When installing modules using clamps on the short side of the frame, the applicable product
types and installation locations are shown in figure 6 and table 5.
