implie . There is no provision on the compensation scheme for the loss, mo ule amage or other
expenses irectly cause by or relate to the installation, operation, use or maintenance of
mo ules. If the patent right or the rights of a thir party are infringe ue to the use of mo ules,
AIKO will not bear any relevant responsibilities. AIKO reserves the right to change the pro uct
manual an this installation manual without prior notice.
If the customer fails to follow the requirements liste in this manual uring the installation
of mo ules, the limite warranty provi e to the customer will be invali . At the same time, the
recommen ations in this manual are to improve the safety of mo ules uring installation, an have
been teste an verifie by practice. Please provi e this manual to the owners of photovoltaic
system for reference, an inform them of all relevant safety, operation an maintenance
requirements an suggestions.
、Regulation and rules
The mechanical installation an electrical installation of PV mo ules shall refer to
correspon ing regulations, inclu ing electrical law, buil ing law an power connection
requirements. These regulations vary from installation site to installation site, such as buil ing roof
installation, vehicle mounte applications, etc. Requirements may also vary epen ing on the
voltage an current nature (DC or AC) of the installe system. Please contact the local authority for
specific terms.

3、General information
3.1 Module identification
Three kin s of visual labels provi e by AIKO’s mo ules:
Nameplate：Pro uct type, rate power un er stan ar test con itions (STC), rate current,
rate voltage, open circuit voltage, short circuit current un er STC, certification mark, maximum
system voltage an other information
Serial number：Each mo ule has a unique serial number. This serial number is printe on
the bar co e an place in the assembly before lamination, an cannot be torn or coate after
lamination. In a ition, an i entical serial number can be foun on or next to the mo ule
nameplate.
Current grading label(if necessary): The mo ules of the same gear are secon gra e by
rate current an marke for ifferentiation on the mo ules.

3. Wiring mode
The junction box of AIKO ABC photovoltaic mo ule is locate in the mi le. Please refer to the
following table for the series connection mo e of various mo ules.
3.3 General safety
The esign of AIKO PV mo ule complies with IEC-61215 an IEC-61730 international
stan ar s. The application level is class A. the mo ule can be use for systems with DC 50V or
above 240W that the public may contact. The safety level of the mo ule is class II an the fire
protection level is class C.
No matter whether the PV mo ule is connecte to the system or not, appropriate protective
measures shall be taken when contacting the mo ule, such as insulating tools, safety helmets,
insulating gloves, safety belts an safety insulating shoes. When you nee to install, groun , wire
an clean mo ules, please be sure to use appropriate electrical safety protection tools.
Un er the sunlight, whether the mo ule is connecte with the electrical system or not, it can

8 / 7
generate irect current, an touching the live parts of the mo ule (such as connectors) may cause
casualties. Avoi irect contact with photovoltaic mo ules, which may cause electric shock or cuts.
The installation of PV mo ules shall comply with the laws an regulations clearly stipulate by
the relevant regions an countries where the PV mo ules are installe . If necessary, the construction
permit an other certificates shall be obtaine first.
The installation of PV mo ules shall be carrie out by qualifie professionals who have
professional skills an knowle ge an are familiar with the mechanical an electrical requirements
of the system. The risk of possible injury uring installation, inclu ing electric shock or cuts, shall be
known in a vance.
The roof system can only be installe on the roof with formal an complete structural analysis
results after evaluation by construction experts.
Observe the safety rules for all installe mo ules. For example, wires an cables, connectors,
charging controllers, inverters, batteries, etc., only equipment, connectors, wires an supports
matching the solar power system can be use . If the photovoltaic system uses batteries, it shall
follow the opinions of the battery manufacturer.

It is necessary to ensure that the connecting cable is fixe on the support frame for the
installation of PV mo ules.
Where animals an chil ren can reach, cables must be protecte with con uits.
Please o not artificially mo ify or remove any mo ules an labels of PV mo ules.
Please o not install PV mo ules without safety precautions.
Do not use any means other than connectors for electrical connection.
The amage PV mo ule has the risk of electric shock an fire an shoul be replace
imme iately.
The installation of PV mo ule array must be carrie out un er the con ition of electrical safety.

9 / 7
During installation, the voltage of PV mo ules in series shall not excee the maximum system
voltage.
It is forbi en to plug connectors of ifferent manufacturers an mo els into each other.
Please o not use conventional PV mo ules to replace roof an wall materials.
