Safety

Do not scratch the coating surface of the frame.
Scratches may decrease the total solar output
due to corrosion of the frame.

Do not artificially concentrate sunlight on the solar
module surface. Failure to comply may result in
product damage or failure.

Do not apply a shock to the junction box of the
module or pull the cable. Do not remove the
labels attached to the module. Failure to comply
may result in damage of the product.

If the installing modules on curved surface, (e. g.
arch type), as shown in the below picture, do not
forcefully modify the module in the installation
when connecting it with the structure. Only install
the module in the place where the structure for
the panels has been properly set up. An improper
structure may cause deformation of the panels.
Panels may also be damaged by unapproved
installation methods such as the use of a crane.

The instructions related to safety and use indicated in
the this installation manual are intended for the
prevention of unexpected danger, damage, or failure.

Non-compliance with the instructions may cause
product damage, product failure, and/or serious
bodily injury or death.

Do not contact electrically active parts of the
panel, such as terminals, without appropriate
safety gear. Contact may result in lethal spark or
electric shock.

Do not use or install if the module is broken or torn.
Failure to comply may result in electric shock.

Perform all work in dry conditions and use only dry
tools. Do not handle wet panels without appropriate
protection equipment. Failure to comply may result
in accident or death. accident or death.

Damaged modules must be treated with safety
protection equipment. Failure to comply may
result in serious bodily injury or death.

Do not approach the damaged or broken module
unless you are an authorized or qualified expert.
Failure to comply may result in serious bodily
injury or death.

Use proper equipment, connectors, wires and
buttresses for the installation of the module. Failure
to comply may result in product damage, product
failure or bodily injury.

Installation during rain, heavy wind or snowy day
may result in bodily injury or death.

Holes in the frame or glass of the module may
decrease the strength of the frame or break the
glass.

Do not touch the glass surface or frame of the solar
module after installation of the module. It may result
in injury or death.

Heavy objects must be kept off of the solar module.
Do not stand on or step on the module. Do not drop
the module. Failure to comply may result in product
damage, product failure or bodily injury.

Electrical Installation

Before & After Installation

• Dirt build-up on the surface of the panel may cause
active solar cells to be shaded and electrical
performance to be impaired.

• Always keep the back surface of the panel free
from any foreign objects or structural elements
which could come into contact with the panel.

After Installation

• Plug in the connector tightly and ensure that the
wiring properly works.

• Conduct periodic inspection of the panels for
damage to front glass, back sheet, frame, junction
box, or external electrical connections.

• Check electrical connections for loose connections
and corrosion.

• Removal of dirt from the front glass can increase
output.

• Water, ethanol or a conventional glass cleanser
with a micro-fiber cloth can be used for regular
washing or rinsing of the front glass to remove
dust, dirt or other deposits.

• Aggressive and abrasive cleansers or chemicals
such as alkali chemicals including ammonia based
solution should not be used on cleaning the module.

• Always wear rubber gloves for electrical insulation
while maintaining, washing or cleaning panels.

• Deposits of foreign material on the frame surface
can be cleaned by using a wet sponge or cloth and
dried in air or by using a clean chamois.

• Perform the wiring work by connecting the
connector and wires to the stand away from the
roof or ground.

Before Installation

Please carefully read this manual before installation.

• Contact with electrically active parts of the panels,
such as terminals, may result in burns, sparks and
lethal shock whether the panel is connected or
disconnected.

• Panels produce voltage even when not connected
to an electrical circuit or load.

• Solar module installation and maintenance must be
performed by qualified and authorized installer.

• All installation instructions should be read and
understood before performing any installation.

• Do not twist, pull, or scratch the cable attached to
the solar module.

• Do not touch the solar module with bare hands.
Failure to comply may result in a serious burn or
injury.

• Do not drop the solar module or place weight on a
solar module.

• Do not disassemble the solar module.

• After installation or repair, check that the solar
module are operating properly.

• In the event that the currently used solar module or
parts have been replaced the newly replaced
module and parts must have the same model
name and parts as the previously installed solar
module.

• Secure all necessary permits and licenses to install
the solar modules

• Only qualified and authorized individuals are
permitted to treat electrical parts, when there is a
breakage, failure or damage of the product or
damage of the product.

• Do not use or install broken modules; Failure to
comply may result in fire, electric shock, and injury.

• Do not install the module horizontally. Failure to
comply may result in excess dirt or white
efflorescence (glass disease).

• Panels are not intended for use indoors or on
moving vehicles of any kind.

• Reflection from external environments such as
snow Reflection from external environments such
as snow, water or other surfaces may increase the
power generated by the panel.

• Industry standard rated specifications are made at
conditions of 1000W/m 2 irradiance and 25 °C
(77ºF) solar cell temperature. Colder temperatures
may substantially increase voltage and power.

• Keep the solar module and system away from
children at all times.

• Keep the module packed in the carton until the
time of installation.

• Keep flammable gasses away from the installation
site.

• Do not work alone. Please work as part of a team
of two or more people.

• Safety harness use is strongly recommended for
installation.

• Partial shadowing may substantially reduce panel
and system output.

• Care must be taken to avoid low tilt angles which
may cause dirt to buildup on the glass against the
frame edge.

Danger

• Avoid all electrical hazards when installing, wiring,
operating and maintaining all panels.

• Do not connect panels that have different electrical
properties or physical configurations in the same
system.

• Match the polarities of cables and terminals when
making the connections; failure to do so may result
in damage to the panel.

• The rating of the over-current device shall not
exceed the maximum series fuse rating marked on
the name plate.

• The panel contains factory installed bypass diodes
located inside the junction box.

• When installing the system, it is recommended to
install a lightning rod to protect the system.
