Mounting With Bolts - Jinko Solar JKM P-60 Series User Manual

When mounting modules in snow-prone or high-wind environments, special care should
be taken to mount the modules in a manner that provides sufficient design strength while
meeting local code requirements.
(4) Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers,
flat washers and the like) is used to attach a listed grounding/bonding device, the
attachment must be made in conformance with the grounding device manufacturer's
instructions.
(5) Common hardware items such as nuts, bolts, star washers, lock washers and the like
have not been evaluated for electrical conductivity or for use as grounding devices and
should be used only for maintaining mechanical connections and holding electrical
grounding devices in the proper position for electrical conductivity. Such devices, where
supplied with the module and evaluated through the requirements in UL1703, may be
used for grounding connections in accordance with the instructions provided with the
module.
(6) The use of third party grounding device is not allowed unless the grounding device is
UL2703 certified with Jinko modules. The installation of that grounding hardware must
follow the grounding manufacture's installation manual.
(7) The clearance between the module and the roof deck should be a minimum of 6 inches
(15mm).

2.3.1 Mounting with Bolts

The frame of each module has 8 or 12 mounting holes used to secure the module to the
support structure. The module frame must be attached to a mounting rail using M8
corrosion-proof bolts together with spring washers and flat washers in eight symmetrical
locations on the PV module. The applied torque value should be big enough to fix the
modules steadily. The torque value for a M8 bolt is 16~20 N*m. For special racking systems
or special installation requirements, please reconfirm with the supplier for the appropriate
torque value. Please find detailed mounting information in figure 3. The installation
instructions shall specify that the modules have been evaluated by UL for bolt mounting
using the 8 provided mounting holes in the frame with a torque of 16~20 N*m. The following
M8 stainless steel mounting hardware should be included in the installation instructions:
For eight 14x9 holes and four 10x7 holes（Red label for mounting hole), mounting hardware
