SAFETY
The instructions related to the safety indicated in the
following are for preventing unexpected danger or
damage in advance by safely and exactly using the product.
DANGER
Non-compliance of the instructions may immediately
cause serious injury or death.
WARNING
Non-compliance of the instructions may cause death or
serious injury to the user.
CAUTION
Non-compliance of the instructions may cause injury or
property damage to the user.
DANGER
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.
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.
No electrical parts like cables are
located after installation between
laminate and mounting structure.
Do Not reconnect or repair
junction box cable. It may occur
spark or electric shock.
Do not bending junction box's
cable. While under stress, it may
occur module damage. Cable
bending radius should be more
than 4 times the cable diameter,
at least.
WARNING
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.
Damaged modules must be
treated with safety protection
equipment. Failure to comply
may result in serious bodily injury
or death.
CAUTION
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.
03
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.

Occurrence
of space
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.
Partial shadow must be removed
from solar module because it can
cause severe problems of solar
module.

BEFORE & AFTER INSTALLATION
Before Installation
Please carefully read this manual before installation.
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 touch the solar module with bare hands.
•
It may result in a burn or injury.
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.
Do not let anyone approach the solar module who has
•
little knowledge of solar modules or on the measures to
take when solar modules are damaged in order to avoid
the risk of injury or electrical shock.
Secure all necessary permits and licenses to install
•
the solar modules.
Do not locate the solar module horizontally, as this may
•
cause dirt or white efflorescence(glass deformation).
Panels are not intended for use indoors or on moving
•
vehicles of any kind.
Industry standard rated specifications are made at
•
conditions of 1000W/m irradiance and 25°C (77°F)
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.
Be careful not to damage the cable when using a tool
•
such as a knife to remove the cable tie that fixes the
junction box cable.
2
Partial shadowing may substantially reduce panel and
•
system output and may be the reason for the damage
of solar module.
Care must be taken to avoid low tilt angles which may
•
cause dirt to buildup on the glass against the frame
edge.
Dirt build-up on the surface of the panel may
•
cause active solar cells to be shaded and electrical
performance to be impaired.
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.
PV panels can operate effectively without ever being washed,
•
although 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.
•
Do not use ground water containing calcium carbonate
components when cleaning glass.
Aggressive and abrasive cleansers or chemicals such
•
as alkali chemicals including ammonia based solution
should not be used on cleaning the module.
Always keep the back surface of the panel free from
•
any foreign objects or structural elements which could
come into contact with the panel, especially when the
panel is under mechanical load.
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.
Do not use any kind of oil or lubricant on the module's
•
any parts, It can defect the PV Module.
