Mounting Instructions; Mounting Method: Bolting - Canadian Solar CS5AH-180M Installation Manual Of Replacement

6.0 MOUNTING INSTRUCTIONS

The applicable regulations pertaining to work
safety, accident prevention and securing the
construction site must be observed. Workers
and third party personnel shall wear or install fall arrest
equipment. Any third party need to be protected against
injuries and damages.
 The mounting design must be certified by a registered
professional engineer. The mounting design and
procedures must comply with all applicable local codes
and requirements from all relevant authorities.
 The module is considered to be in compliance with UL
1703 or UL 61730 and IEC 61215 only when the module
is mounted in the manner specified by the mounting
instructions included in this installation manual.
 The system designer and installer are responsible for
load calculations and for proper design of support
structure.
 Any module without a frame (laminate) shall not be
considered to comply with the requirements of UL 1703
or UL 61730 unless the module is mounted with
hardware that has been tested and evaluated with the
module under this standard or by a field Inspection
certifying that the installed module complies with the
requirements of UL 1703 or UL 61730.
 Canadian Solar does not provide mounting hardware.
 Classic modules can be mounted onto a support
structure using one of several approved methods as
described below. For
installation methods,
representative. Failure to use a recognized installation
method will void the Canadian Solar warranty.
 Use appropriate corrosion-proof fastening materials.
All mounting hardware (bolts, spring washers, flat
washers, nuts) should be hot dip galvanized or stainless
steel.
 Use a torque wrench for installation.
 Do not drill additional holes or modify the module
frame. Doing so will void the warranty.
 Classic modules can be installed in either landscape or

portrait orientations. Refer to the detailed instructions
for further guidance. Please note that in areas with
heavy snowfall (> 2400 Pa) further countermeasures
such the use of additional support bars should be
considered to avoid snow loads damaging the lowest
row of modules.
 In cases where an
recommended to improve both mechanical stability
and long-term module performance, we recommend
selecting a sufficiently resistant material. Canadian
Solar recommends bars with a minimum thickness of
50 mm (1.97 in). The support bar centerline should be
positioned within 100 mm (3.94 in) of the side frame
centerline (slight shifts may be necessary to access
module grounding holes).
 The loads described in this manual correspond to test
loads. For installations complying with IEC 61215-
2:2016 and UL 1703 or UL 61730, a safety factor of 1.5
should be applied for calculating the equivalent
maximum authorized design loads. Project design
loads depend on construction, applicable standards,
location and local climate. Determination of the design
loads is the responsibility of the racking suppliers
and/or professional
information, please follow local structural code or
contact your professional structural engineer.

6.1 MOUNTING METHOD: BOLTING

 The mechanical load test with these mounting methods
were performed according to IEC 61215.
 Modules should be bolted to supporting structures
through the mounting holes in the rear frame flanges
only.
 Each module must be securely fastened at a minimum
of 4 points on two opposite sides.
 M8 X 1.25 - Grade 8.8 (5/16"-18 Grade B7) galvanized or
A2-70 stainless steel bolt and nut should be used.
 The yield strength of bolt and nut should not be less
than 450MPa.
 Tightening torques should be 16~20 Nm (11.8~14.75 ft-
lbs) for M8 (5/16"-18) coarse thread bolts, depending on
additional support bar
engineers. For detailed
