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 goggles
and tape the glass to keep the broken pieces in place.
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
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. Please don't keep PV modules without grounded condition by
minus-pole for three months after series connection. Otherwise,
TCO corrosion may be caused.
< 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 at the back sheet. The back sheet is
vulnerable.
5. Do not hit on the terminal box or do not pull the cables. The
terminal box can crack and break.
6. Never touch terminal box or the end of output cables with bare
hands when the PV module is irradiated. Cover the surface of PV
module with cloth or other suitable sufficiently opaque material to
isolate 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 insulation
of output cable can break and may result in electricity leakage or
shock.
8. Do not pull the output cable excessively. The output cable may
unplug and cause electricity leakage or shock.
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 insulation coating of the frame (except for
grounding connection). It may cause corrosion of the frame or
compromise the framework strength.
11. Do not loosen or remove the screws of the PV module. It may
compromise the joint strength of PV module and cause corrosion.
12. Do not touch the PV module with bare hands. The frame of PV
module 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 try artificially to concentrate sunlight on the PV module.
15. Do not grab the PV module at only one side. The frame may bend.
Grab the PV module at two sides facing each other.
< INSTALLATION SAFETY >
1. Always wear protective head gear, insulating gloves and safety
shoes (with rubber soles).
2. Keep the PV module packed in the carton until installation.
3. Do not touch the PV module unnecessarily during installation. The
glass surface and the frames get hot. There is a risk of burn, or you
may collapse because of 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. Plug in the connector tight and ensure the wiring work.
11. Due to the risk of electrical shock, do not perform any work if the
terminals of PV module are wet.
12. Do not touch the terminal box and the end of output cables 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.
13. Do not unplug the connector if the system circuit is connected to a
load.
14. Do not stomp on the glass at work. There is a risk of injury or
electric shock if glass is broken.
15. Do not work alone (always work as a team of 2 or more people).
16. Wear a safety belt if working far above the ground.
17. Do not wear metallic jewelry which can cause electric shock during
installation.
18. Do not damage the back sheet of PV modules when fastening the
PV modules to a support by bolts.
19. Do not damage the surrounding PV modules or mounting structure
when replacing a PV module.
20. Bind cables by the insulation locks. Drooping down of cables from
the terminal box could possibly cause various problems such as
animal biting, electricity leakage in puddle.
21. Take proper measures for preventing the laminate (consisted of
resin, cells, glass, back sheet, etc.) from dropping out of the frame
in case the glass is broken.
22. Cables shall be located so that they will not be exposed to direct
sunlight after installation to prevent degradation of cables.

4. SITE SELECTION
In most applications, the PV modules should be installed in a location
where there is no shading throughout the year. In the Northern
Hemisphere, the PV modules should typically face south, and in the
Southern Hemisphere, the PV modules should typically face north.
