① How to use a frame installation hole
1) Installation angle
Please install the module at the angle having the most annual cumulative amount of solar radiation in the applicable site.
2) Confirmation matter
To improve module's electrical insulation and durability, the back side [Junction Box] of module should be protected to avoid exposure to moisture, and PV module
wiring should be installed considering thermal expansion due to ambient temperature and vibration due to wind. When a PV module is installed on a roof, between
the back side of the PV module and roof is maintained at a sufficient distance(minimum above 2 inch) to be well ventilated. According to the laws of the applicable
site, the PV module can be installed on a fire resistance roof. The PV module's fire rating is "C".
3) Installation hole
The method of installing a frame hole passed a mechanical load test item in accordance with the IEC61215 standard, and S-Energy Co., Ltd. recommends the
following method of installing a frame hole. As described in figure 1, an installation hole is inserted in the frame, if the frame is randomly processed or the
installation hole is changed, the module will be damaged or the strength of frame will be declined.

Bolt Torque: 16Nm ~ 20Nm [Newton-meters]
60series Bolt size: M6 L16 Bolt, [PV Support T: ≤4mm]
72series Bolt size: M6 L20 Bolt
Caution
1) Be careful to avoid sealing the gap between the module and the structure,
because the area should be well ventilated. The module of power
performance and life can be affected, if the space between the module
and structure is sealed.
2) Please leave a space between the modules because the module can be
expanded or be shrink depending on the ambient temperature.
3) In case of failure to use the accessories recommended by S-Energy Co.,
Ltd., it may affect the long term reliability of the module, and S-Energy Co.,
Ltd. do not take any responsibility for life-shortening of the module
resulting from such use.
