Installation Method: Clamps - Hyundai KN Series Manual

Installation method: Clamps

Use a certain number of clamps to secure the modules to the mounting rail. Hyundai Energy Solution recommends that fixtures be
clamped to the frame of module.
The clamps shall be made of anodized aluminum alloy or stainless steel.
The length and thickness of the clamp recommended by Hyundai Energy Solution are ≥50mm and 3mm
respectively. The contact width between the clamps and the side of the frame is in the range of 7 ~ 11 mm.
Install and tighten on the mounting rails with the torque specified by the mounting components manufacturer. The clamps is
installed with m 8 × 1.25 bolts and nuts. For M8 heavy thread bolts, the tightening torque should be between 16 Nm and 20 Nm depending
on the bolt grade.
When installing the clamps, do not touch the front glass, and do not scratch or deform the aluminum frame during the installation
process. At the same time, the clamps cannot affect the operation of the module， and make sure that the drainage hole and the
grounding holes are not blocked.
Each module requires at least four clamps to be secured, and at least two clamps for each long or short frame, depending on local
application conditions (wind and snow conditions) , an additional number of clamps may be required to ensure that the modules and
systems bear the corresponding loads, as shown in Figures 7.
Clamps position is critical to the reliability of installation，center line must be installed as described in the following table according
to structural and load requirements.
