There are 12 mounting holes on the frame of each module. Under normal circumstances, 4 1/4
L installation holes can be used. In areas with high wind load and heavy snow, it is recommended to
add 4 additional installation points (4 outside installation holes).
Secure module in each position using bolts, washer, spring washer and nut and tighten to 16-
20N ▪M torque.
5.3.2.2
Installation of pressing block(clamping)
The fixture must have an overlap of at least 7mm to 10mm with the module frame mounting
width
。
Use at least 4 clamps to attach the module to the mounting bracket.How many clamps to use
depends on the local wind and snow pressure intensity. If the pressure exceeds the expected
estimate, additional clamps or supports are required to ensure the assembly can withstand the
pressure. The torque applied during installation should be large enough for the assembly to hold
well (16-20n ▪m).
