3. GENERAL INFORMATION
(INCLUDING WARNING AND SAFETY)
The installation of PV modules requires a great degree of skill and
should only be performed by a qualified licensed professional,
including licensed contractors and licensed electricians. Please be
aware that there is a serious risk of various types of injury occurring
duringtheinstallationincludingtheriskofelectricshock.AllSHARP
PV modules are equipped with a permanently attached junction
box that will accept variety of wiring applications or with a special
cable assembly for ease of installation, and they do not require
special assembly.
< GENERAL WARNING >
1.
PV modules are heavy. Handle with care.
2.
Before you attempt to install, wire, operate and maintain the
PV module, please make sure that you completely
understand the information described in this installation
manual.
3.
Contact with electrically active parts of a PV module such as
terminalscanresultinburns,sparksandlethalshockwhether
the PV modules is connected or not.
4.
PVmodulesproduceelectricitywhenthesufficientsunlightor
other sources illuminate the module surface. When the
modulesareconnectedinseries,voltageiscumulative.When
the modules are connected in parallel, current is cumulative.
Asaresult,alarge-scalePVsystemcanproducehighvoltage
and current which could present an increased hazard and
may cause serious injury or death.
5.
Do not connect the PV modules directly to the loads such as
motor since the variation of the output power depending on
the solar irradiation causes damage for the connected motor.
1:Inthecaseofabrushlessmotor,thelockfunctionbecomes
active and the hall IC is most likely to be damaged.
2: In the case of a brush type motor, the coil is most likely to
be damaged.
6.
In case of snow build-up, snow would slide easier on the
smooth surface of the module than other parts of the roof.
Snow may suddenly slide, fall off the roof and hit nearby
objects/areas.Takepreventivemeasures(e.g.snowstopper)
when there is possible risk such case would cause an injury
or a damage.
< GENERAL SAFETY >
1.
Consult local codes and other applicable laws concerning
required permits on regulations concerning installation and
inspection requirements.
2.
BeforeinstallingaPVmodule,contactappropriateauthorities
to determine permit, installation and inspection requirements
that should be followed.
3.
Install PV modules and ground frames in accordance with
applicable rules and regulations.
4.
PV modules should be installed and maintained by qualified
personnel. Only installer/servicer personnel should have
access to the PV module installation site.
5.
No matter where the PV modules are installed, either roof
mounted construction or any other type of structures above
the ground, appropriate safety practices should be followed
and required safety equipment should be used in order to
avoid possible safety hazards. Note that the installation of
some PV modules on roofs may require the addition of
fireproofing, depending on local building/fire codes.
GENERAL INSTRUCTIONS
6.
In the case that the PV modules are non-integral type, the
module is to be mounted over a fire resistant roof.
7.
Please use PV modules with same cell size within series.
8.
Followallsafetyprecautionsofothercomponentsusedinthe
system.
9.
Inordertoavoidariskofinjuryorelectricalshock,donotallow
anyone to approach the PV module if the person has little
knowledgeonPVmoduleoronthemeasuresthatshouldbe
taken when PV modules are damaged.
10. Do not shade portions of the PV module surface from the
sunlightforalongtime.Theshadedcellmaybecomehot(hot
spot phenomenon) which results in solder joints peeling off.
Shading causes drop in generated power and/or operation
failure of the PV modules.
11. Donotcleantheglasssurfacewithchemicals.Donotletwater
stay on the glass surface of PV modules for a long time. This
creates a risk of white efflorescence (glass disease) which
may result in the deterioration of energy generation.
12. Do not install the PV module horizontally. It may cause dirt or
white efflorescence (glass disease) due to water.
13. Do not cover the water drain gap of the frame. There is a risk
offrostdamagewhentheframeisfilledwithwatercumulation.
14. Whenslidingsnowloadhastobeconsidered,anappropriate
measure has to be taken so that PV module frames on lower
edge of PV modules will not be damaged.
15. Do not expose PV module to sunlight concentrated with
mirrors, lenses or similar means.
16. Turn off inverters and circuit breakers immediately, should a
problem occur.
17. In case the glass surface of a PV module is broken, wear
gogglesandtapetheglasstokeepthebrokenpiecesinplace.
18. A defective PV module may generate power even if it is
removedfromthesystem.Itmaybedangeroustohandlethe
PV module while exposed to sunlight. Place a defective PV
module in a carton so PV cells are completely shaded.
19. Incaseofseriesconnection,themaximumopencircuitvoltage
must not be greater than the specified maximum system
voltage. The voltage is proportional to the number of series.
In case of parallel connection, please be sure to take proper
measure (e.g. fuse for protection of module and cable from
over current, and/or blocking diode for prevention of
unbalanced strings voltage) to block the reverse current flow.
The current may easily flow in a reverse direction.
20. Keep modules away from children.

7. INSTALLATION
Refer to installation manual of PV module.
8. ELECTRICAL RATINGS
Refer to installation manual of PV module.
9. GROUNDING
The frame grounding must consider the local requirement and
regulation at the site of installation. When grounding is required,
please refer to below example connection (Figure 3).
Please be careful in arranging the system ground so that the
removalofonemodulefromthecircuitwillnotinterruptthegrounding
of any other modules.
The modules should be grounded to the same electrical point as
described below.

Figure 3. Example of acceptable ground connection
Each PV module has a hole on the side frame for either a bolt, nut
and washer grounding the module to the frame, a ground lug
fastened by bolt or screw, or appropriate screw (hardware not
provided). Near the hole for ground, either " " or " G " is indicated
as ground symbol. An example of acceptable ground connection

3. In a connection of this type, the hardware (such as a toothed
locked washer/star washer) must score the frame surface to make
positive electrical contact with the frame. The ground wire must be
considered within the local requirement and regulation at the site of
installation.
10. MOUNTING
Pleasemakesurethatalltheinformationdescribedintheinstallation
manual is still valid and proper for your installation. The mounting
method has been verified by SHARP and NOT CERTIFIED by a
third party organization.
The approved way to mount Sharp PV modules to a support
structure is using the bolt holes provided as described in the
Specifications. Although Sharp does not specify or warrant frame
clips or clamps, using frame clips (not provided) or clamps (not
provided) is also possible when they are designed for PV modules
and with minimum dimensions on the sides of the module in
accordance with the instructions and drawings provided. If using
frameclipsorclamps,themodulesshouldbefixedrigidlyandthere
shallbenodamagetothemodulesbydeformingmountingstructure
against design load. The Sharp module guaranty may be void if
customer-selected frame clips which are improper or inadequate
withrespecttothemoduleproperties(includingstrengthormaterial)
orinstallation.Notethatifmetalclipsareused,theremustbeapath
to ground from the clips, (for instance, using star washers in the clip
hardware set).
Pleasereviewthedescriptionsanddrawingscarefully;notmounting
the modules according to one of these methods may void your
guaranty. These mounting methods are designed to allow module
loading of 2400Pa. Support structures that PV modules are
mounted on should be rigid. Sharp PV modules are designed to
secure their electric performance under the condition that they are
mounted on rigid support structures. Deformation of support
structure may damage PV module with its electric performance.
Whenmountingthemoduleonstructure,ensurethatnocornerhas
a displacement of more than 2mm per every 1000mm of the
diagonal.
11. MAINTENANCE
The modules are designed for long life and require very little
maintenance. If the angle of the PV module is 5 degrees or more,
normal rainfall is sufficient to keep the module glass surface clean
undermostweatherconditions.Ifdirtbuild-upbecomesexcessive,

the back side materials. In order to ensure the operation of the
system, please check the connection of wiring and the state of the
jacket of wires every now and then.
For PV modules with anti-reflective coating glass (NU-R250J5 to
NU-R240J5 and ND-R250A5 to ND-R220A5), do not touch the
glass since finger prints or stains will easily mark the glass. If dirt
