2. 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 and appropriately licensed
professional, including licensed contractors and licensed electricians.
Please be aware that there is a serious risk of various types of injury
occurring during the installation including the risk of electric shock.
SHARP PV modules are either equipped with a permanently attached
junction terminal box that will accept a variety of wiring applications or
equipped with a pre-terminated cable assembly for ease of installation.

< 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
terminals can result in burns, sparks and lethal shock whether the

4. Do not touch any surface of module.

5. Do not place/drop objects on the PV module.

6. Do not disassemble or attempt to repair the PV module by
yourself.

7. Do not drop the PV module.

8. Do not damage, pull, bend, or place heavy material on cables.

9. Upon completion of any service or repairs, ask the
installer/servicer to perform routine checks to determine that the
PV modules are in safe and proper operating condition.

10. When replacement parts are required, be sure the
installer/servicer uses parts specified by the manufacturer with
same characteristics as the original parts. Unauthorized
substitutions may result in fire, electric shock, or other hazard.

11. Consult your local building and safety department for required
permits and applicable regulations.

PV module is connected or not.

4. PV modules produce electricity when the sufficient sunlight or other
sources illuminate the module surface. When the modules are
connected in series, voltage is cumulative. When the modules are
connected in parallel, current is cumulative. PV systems can
produce high voltage and current which could present an increased
hazard and may cause serious injury or death.

5. Do not connect the PV modules directly to loads such as motors
since the variable output power of the PV modules (dependent on
solar irradiation) may cause damage to the connected motor.

< GENERAL SAFETY >

1. Consult local codes and other applicable laws concerning required
permits on regulations concerning installation and inspection
requirements.

2. Before installing a PV module, contact appropriate authorities 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.

6. For PV modules that are non-integral type, the modules are to be
mounted over a fire-resistant roof.

7. PV modules connected in series should have the same cell size.

8. Follow all safety precautions of other components used in the
system.

9. In order to avoid a risk of injury or electrical shock, do not allow

- 2 - Installation Manual for PV modules

anyone to approach the PV module if the person has little
knowledge about PV modules or the measures that should be
taken when PV modules are damaged.

10. Do not shade portions of the PV module surface from the sunlight
for a long time. Shaded cells may become hot (hot spot
phenomenon) which may result in permanent damage, e.g.,
solder joints peeling off.

11. Do not clean the glass surface with chemicals. Do not let water
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 reduced energy generation.

12. Do not install the PV module horizontally. It may cause dirt or white
efflorescence (glass disease) due to water. A minimum tilt of 5
degrees from the horizontal is required; a tilt of 10 degrees or more
is recommended (a higher tilt angle will contribute to cleaning the
surface during rainstorms).

13. Do not cover the water drain holes of the frame. There is a risk of
frost damage when the frame has water in it.

14. When sliding snow load has to be considered, an appropriate
measure must be taken so that the lower edge of the PV module
frame will not be damaged.

15. Do not expose PV modules to sunlight concentrated with mirrors,
lenses or similar means.

16. Should a problem occur, immediately turn off inverters and circuit
breakers.

17. In case the glass surface of a PV module is broken, wear goggles
and tape the glass to keep the broken pieces in place prior to
removing the module.

18. A defective PV module may generate power even if it is removed
from the system. It may be dangerous to handle the PV module
while exposed to sunlight. Place a defective PV module in a carton
so PV cells are completely shaded.

19. In case of series connection, the maximum open circuit voltage,
when considering the effect of temperature, must not be greater
than the specified maximum system voltage. Voltage is
proportional to the number of PV modules in 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 reverse current flow; otherwise, current may easily flow in
reverse.

< HANDLING SAFETY >

1. Do not cause an excessive load on the surface of PV module or
twist the frame. The glass surface can easily break.

2. Do not stand or step on the PV module. The surface glass of PV
module is slippery.

3. Do not hit or put excessive load on the glass or back sheet. The PV
cell is very thin and can be easily broken.

4. Do not scratch or hit the back sheet. The back sheet is vulnerable.

5. Do not hit the terminal box; do not pull the cables. The terminal box
can crack and break.

6. Never touch the terminal box or the ends of output cables with bare
hands when the PV module is illuminated. During handling and
installation, cover the surface of PV module with cloth or other
suitable sufficiently opaque material to shield the PV module from
incident light and handle the wires with rubber-gloved hands to
avoid electric shock.

7. Do not scratch the output cable or bend it with force. The cable
insulation can break and may result in electricity leakage or shock.

8. Do not pull the output cable excessively. The output cable may
come undone and cause electricity leakage or shock.

KTA09001 Ver. 3.11

9. Do not drill holes in the frame. It may compromise the frame
strength and cause corrosion of the frame.

10. Do not scratch the coating of the frame (except for grounding
connection). It may cause corrosion of the frame or compromise
the frame strength.

11. Do not loosen or remove the screws in the frame. It may
compromise the strength of PV module and cause corrosion.

12. Do not handle the PV module with bare hands. The frame has
sharp edges and may cause injury.

13. Do not drop PV module or allow objects to fall down on the PV
module.

14. Do not artificially concentrate sunlight on the PV module.

15. Do not lift the PV module by only one side. The frame may bend.
Lift the PV module by holding two (opposite) sides.

< INSTALLATION SAFETY >

1. Always wear protective head gear, insulating gloves and safety
shoes (with rubber soles).

2. If the PV modules are delivered in cartons, keep them packed in
the cartons until installation.

3. Do not touch the PV module unnecessarily during installation. The
glass surface and the frames may become hot. There is a risk of
burn, or electric shock.

4. Do not work under rain, snow or windy conditions.

5. Use insulated tools.

6. Do not use wet tools.

7. Do not drop tools or hard objects on PV modules.

8. When installing PV modules far above ground, do not drop any
object (e.g., PV module or tools).

9. Make sure flammable gases are not generated near the installation
site.

10. Completely cover the PV module surface with an opaque material
during PV module installation and wiring.

11. For modules with connectors, ensure connections are fully plugged
together.

12. Due to the risk of electrical shock, do not perform any work if the
terminals of PV module are wet.

13. Do not touch the terminal box or the cable ends (connectors) with
bare hands during installation or under sunlight, regardless of
whether the PV module is connected to or disconnected from the
system.

14. Do not unplug the connectors if the system circuit is connected to a
load. The connectors are not rated for load-break.

15. Do not stand or stomp on the glass. There is a risk of injury or
electric shock if glass is broken.

16. Do not work alone (always work as a team of 2 or more people).

17. Wear a safety belt if working far above the ground.

18. Do not wear metallic jewelry which can cause electric shock during
installation.

19. Do not damage the back sheet of PV modules when fastening the
PV modules to a support structure.

20. Do not damage the surrounding PV modules or mounting structure
when replacing a PV module.

21. Use UV rated cable ties or other methods to cinch loose cables.
Drooping cables could cause various problems such as facilitating
damages by animals or electricity leakage (from cables lying in
puddles).

22. Take proper measures for preventing the laminate (consisting of
cells, glass, back sheet, etc.) from dropping out of the frame in
case the glass is broken.

23. Cables shall be located so that they will not be exposed to direct
sunlight after installation to prevent degradation of cables.

24. Do not put anything (e.g. tools, clothes, etc.) on the modules
