- 2 - Installation Manual for PV modules
< HANDLING SAFETY >
1.
Do not expose the PV module to excessive loads on the surface of
the PV module or twist the frame. The glass may break.
2.
Do not stand or step on the PV module. The glass may be slippery,
and there is a risk of injury or electric shock if glass is broken.
3.
Do not hit or put excessive load on the glass or back film. PV cells
may break.
4.
To avoid damage to the back sheet, do not scratch or hit the back
sheet.
5.
To avoid damage to the junction box, do not hit the junction box; do
not pull the cables.
6.
Never touch the end of output cables with bare hands when the
module is illuminated. Cover the surface of module with cloth or
other sufficiently opaque material to block the module from incident
light and handle the wires with insulated gloved hands to avoid
electric shock.
7.
Do not scratch the output cable or bend it with force. The insulation
of the output cable may break which may result in electricity
leakage or shock.
8.
Do not pull the output cable excessively. The output cable
connection may become loose 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 frame strength.
11.
Do not loosen or remove the screws from the PV module. It may
compromise the strength of the PV module and cause corrosion.
12.
Do not touch the PV module with bare hands. The frame of the PV
module has sharp edges and may cause injury. Wear suitable
gloves, such as leather gloves with padding in the palm and finger
areas.
13.
Do not drop the PV module or allow objects to fall on the PV
module.
14.
Do not lift the PV module by only one side. The frame may bend.
Always use two hands to lift and carry the PV module on the long
side of the frame.
15.
Some PV modules incorporate one or more support bars on the
back of the module. Do not mount or carry the PV module using
the support bar(s) on the back of the module.
< 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 frame may be hot. There is a risk of burns
and electric shock.
4.
Do not work in rain, snow or windy conditions.
5.
Use insulated tools.
6.
Do not use wet tools.
7.
When installing PV modules, do not drop any objects (e.g., PV
modules or tools).
8.
Make sure flammable gases are not generated or present near the
installation site.
9.
Terminate module-to-module wires in the junction box fully and
correctly. Check all connections.
10.
Due to the risk of electrical shock, do not perform any work if the
terminals of the PV module are wet.
11.
Do not touch the junction box and the end of the output cables
(connectors) with bare hands during installation or under sunlight,
regardless of whether the PV module is connected to or
disconnected from the system.
12.
Do not unplug a connector if the system circuit is connected to an
operating load.
13.
Do not work alone (always work as a team of 2 or more people).
14.
Wear a safety harness when working above the ground.
15.
Do not wear metallic jewelry which may conduct electricity and
enable electric
shock during installation.
16.
Do not damage the back sheet of PV modules when fastening the
PV modules to a support by bolts.
17.
Do not damage the surrounding PV modules or mounting structure
when replacing a PV module.
18.
Use UV resistant materials, wire management hardware to secure
cables. Drooping cables may cause various problems, such as
electricity leakage.
19.
Take proper measures for preventing the laminate (consisting of
encapsulant, cells, glass, back sheet, etc.) from dropping out of the
frame in case the glass is broken.
20.
Cables shall be located so that they will not be exposed to direct
sunlight in order to prevent degradation of cables.
A-3. PV MODULE COMPONENTS
A-4. SITE SELECTION
PV modules should be installed in a location where there is no shading
throughout the year. In the northern hemisphere, PV modules should
typically face south, and in the southern hemisphere, PV modules
should typically face north.
Please make sure that there are no obstructions in the surroundings of
the site of installation. Take proper steps in order to maintain reliability
and safety in case the PV modules are installed in areas that have
heavy snow / extreme cold / strong winds / installations over, or near,
water and areas where installations are prone to salt water exposure or
on small islands or in desert areas. If you are planning to use the PV
modules where salt water damage may occur, please consult with
SHARP to determine an appropriate installation method, or if
installation is possible.
