6.2.2
Pole mounting
When installing a module on a pole, choose a pole and supporting rail that will withstand the anticipated
wind power of the local area. The pole must be constructed on a solid foundation.
6.2.3
Ground mounting
Select the height of the mounting system to prevent the lowest edge of the module from being covered by
snow for a long time in winter in areas with heavy snowfalls. The module shall be installed on the supporting
rail with appropriate height instead of being directly laid on the ground. In addition, the lowest portion of the
module shall be high enough (≥900 mm) from ground, so that it is not shaded by plants and trees, or damaged
by sand and stone driven by wind, or not shaded by the mud splashed by rain water.
6.3 Installation methods
6.3.1
General rules
a)
Modules can be fastened on the supporting system using screw bolts or clamps. Modules must be
installed according to the following methods or instructions. If not the warranty may be void.
b)
Sunerg modules have reached the IEC standard on the mechanical load requirements. When
mounting, fasten the screws through the 4 or 6 symmetrical mounting holes on the inside of the
aluminum bezel or use the pressure clamp to secure the module to the supporting rail, Sunerg
module can withstand the wind pressure of 2400Pa and the snow pressure of 5400Pa (Only the
module models covered in this manual are available
）
, it is recommended that the system designer or
installer perform the load calculations.
c)
The supporting rail and other materials required (such as screw) shall be made of durable, resistance
to environmental corrosion, anti-rust and UV-resistant materials.
6.3.2
Screw installation
6.3.2.1
Use anti-corrosion M8 bolts to fix through the mounting holes on the module frame. Each module
needs to be fixed on 4 or 8 mounting holes, as shown in Table 1 Schematic diagram of mounting holes for
fixed modules. If you need to strengthen the installation, it is recommended to use the 6.3.3 fixture installation
method.
6.3.2.2
When fixing with M8 bolts, spring washers and flat washers must be added to 4 or 8 symmetrical
mounting holes. See Table 1 for bolt fixing diagrams.
The recommended torque for tightening screws is
from12N.m to16N·m
. The recommended accessories are shown in Table1:
