The use of bolt grounding device is not allowed unless the grounding device is UL1703 or
UL2703 certified with Jinko modules. Alternate grounding options built into the racking
system are acceptable as long as they have been UL approved.

f)
The following UL Listed Ground Clamp in combination with the following model number PV
modules can be used. Other third party grounding method can’t be used unless the
grounding device is UL2703 certified with Jinko modules.
g)
Follow the requirements of applicable local and national electrical codes.
h) These modules contain factory installed bypass diode. If these modules are incorrectly
connected to each other, the bypass diodes, cable or junction box may be damaged.
i) The module shall be wired in accordance with the NEC, the grounding method of the
frame of arrays shall comply with the NEC, article 250
j)

shall be in accordance with CSA C22.1, Safety Standard for

Installations, Canadian Electrical Code, Part 1.
k)
It is recommended that the M8 bolt be tightened to a torque of about 16
~
20
N*m .
l)
The cable of the junction box is defined as L1, as showed below. For Jinko standard
module, L1 is 900/1200mm; and for customized module, L1 can be based on your
condition, take the cable length into consideration before designing the wiring layout
.
m) Jinko Solar requires the negative grounding of the inverter when a system is installed
with standard (non-Eagle line) PV solar modules. Alternatively, a "charge-equalizing‟
device may be used to mitigate the effects of the Potential Induced Degradation (PID)
phenomenon that can occur in specific environments that the array is installed in.

4. Maintenance and
C
are
a) A build up of dust or dirt on the module(s) front glass will result in decreased energy
output. Clean the module(s) preferably once annually if possible (depending on site
conditions) using a soft dry or damp cloth, as necessary.
b)
Never use abrasive material under any circumstances.
