checked in accordance with the applicable
regulations and standards before work is
started.
•
Use the marked 5.5 mm grounding holes to
ground the anodized frame. Use one M5 nut,
two M5 cut washers, one M5 plain washer,
one M5 spring washer, and one M5 bolt and
the copper wire. All nuts, bolts, and washers
are type M5 and should be made of stainless
steel.
•
Put the bolt through the cup washer and
wrap the copper wire around the bolt. (Note
that the copper wire cannot be attached
directly to the aluminum.)
•
Put the bolt through the cut washer and then
through the hole in the aluminum frame.
Add the spring washer and nut on the other
•
side of the bolt and tighten to secure all parts.
The tightening torque should be 4~4.5 N•m.

It is required to perform regular inspection and
maintenance of the modules, especially within
warranty scope. It is the user's responsibility to the
report to the supplier regarding the damages found
in time.
8.1 Routine inspection
Regular inspections should be made to see if the
photovoltaic modules in the photovoltaic array are
damaged, such as glass breakage, cable breakage,
junction box damage, cell damage, backplane
breakage and other factors that lead to functional
and safety failures of photovoltaic modules. When
the above problems occur, the supplier must be
notified in time to replace the same type of
photovoltaic modules.
It is recommended to perform a preventive
inspection every 6 months, and do not replace the
components of the photovoltaic module without
authorization.
performance inspection or maintenance is required,
it is recommended that qualified professionals
perform the operation to avoid electric shock or
personal injury.
Routine maintenance measures should be taken to
keep the photovoltaic modules free of snow, bird
droppings, seeds, pollen, leaves, branches, dust,
stains, etc.
