1 About these instructions
These instructions contain information about safe handling of
KYOCERA solar modules of the KK-series.
They are directed at personnel with electro-technical qualifications and contain safety-relevant instructions for the assembly, connection and maintenance of the solar modules.
IMPORTANT
The solar modules may only be mounted by personnel with
electro-technical qualifications. Appropriately qualified technicians must always be deployed to service the units or remedy
faults during operation.
Please read these instructions carefully before handling the
solar module and familiarise yourself with the safety information. After the module has been installed, hand over these
instructions to the operator of the solar modules for safekeeping.
2 Description of the solar modules
2.1 Proper use
The solar modules use the photovoltaic principle to turn light
into electricity. The solar modules are primarily designed for
connection to an inverter to feed the energy into the public
power grid. When connecting to a charge controller, please
observe the instructions of the manufacturer of the charge
controller and accumulator. Several solar modules can be
connected in series or in parallel.
The solar modules may not be directly connected to electrical
consumers.
2.2 Description
The solar modules have an aluminium assembly frame with
assembly and grounding holes. The solar modules have a
junction box and solar cables with plugs for the electrical
connection. Appendix 1 of these instructions contains an
illustration of a solar module.

② Junction box
③

⑤ Solar cable
The solar modules are equipped with bypass diodes. In the
event of clouding, these minimise the losses and help to
prevent damage to the solar modules. The solar modules are
not equipped with blocking diodes preventing battery discharging at night. Most PV charge regulators incorporate
nighttime disconnect feature. The solar modules comply with
the application class A in accordance with IEC 61730-1.

3 Safety
Solar modules generate power, producing voltage and current as soon as they are exposed to light. A single solar module generates a voltage of below 50 VDC; if several modules
are connected in series, the voltages of the individual modules accumulate and can pose a hazard.
Hazard!
Potentially fatal risk due to electrical shock if
damaged solar modules are touched.
•
Only touch solar modules with fractured or
broken front glass or a damaged rear foil if
you are wearing rubber gloves.
•
Only touch damaged solar modules if it is
NOTE
The frame of the solar module may have sharp edges and
may cause injury. Wear suitable gloves, such as leather
gloves with padding in the palm and finger areas.
absolutely necessary.
Warning!
Risk of falling when working on roofs.
•
Use suitable fall protection equipment.
Observe the accident prevention regulations.
Warning!
Risk of injury from falling objects.
•
Cordon off a safe distance around the hazardous zone when working on roofs.
Caution!
To avoid damage to the solar module, please
observe the following points:
•
Do not apply paint or any adhesives to the
rear side of the solar module.
•
Never use the junction box or the solar cable
to carry the unit.
•
When handle the modules, do not hold them
by supporting only one side of the long
frame.
•
Do not expose the solar module to concentrated light.
•
Do not allow any objects to fall upon the
solar module.
Avoid scratches to the front glass.
Caution!
Risk of breaking the solar module.
•
Do not walk across or step on the solar
module.
Caution!
Risk of injury by the solar module frame.
•
Do not touch the solar module with bare
hands.
4 Assembly
Assembly work may only be performed by
trained and qualified personnel.
4.1 Safety information relating to assembly
Caution!
KYOCERA solar modules are “non-explosionprotected operating equipment”.
•
Do not install the solar module close to
4.2 Select the location
NOTE
Before installing the PV system, contact local authorities to
determine the necessary permits, installation and inspection
requirements. During assembly, pay attention to the local
building standards.
The solar modules can be installed on roofs or open space on
support structures. To achieve maximum power yields for
feeding into the public grid, the following should be observed
when selecting the installation site: The solar irradiation
should be as high as possible distributed throughout the year.
To this end, the surface of the solar modules in the northern
hemisphere must face south. In Europe, the ideal module
slope is approx. 30° - 40°. W hile a bigger module slope leads
to energy losses, smaller module slope can also lead to high
accumulations of non-slipping snow on the module, which
might cause damages to the module or its frame. Install the
solar modules where they are not shaded by obstacles such
as buildings or vegetation. Pay special attention to avoid
partial shadowing of the solar modules by close-by objects.
The solar modules should not be installed in the area with
direct exposure to saltwater droplet (Guideline : within 50 m of
a saltwater body). In the zone between 50 m and 200 m from
a saltwater body, the PV modules should be installed as roof
mounted only. For more information about the selection of the
site, please contact the KYOCERA customer service.
4.3 Preparatory work for assembly
The solar module must be mounted to a support structure.
Please observe the information provided by the mount manufacturer when selecting the support structure.
If installed on a roof, the solar modules must be mounted on a
fire-resistant surface.
flammable gases or vapours.
Hazard!
Potentially fatal risk if live parts are touched.
•
Cover the solar module with opaque foils or
materials during assembly.
Warning!
Risk of falling when working on roofs.
•
Use suitable fall protection equipment.
•
Do not perform assembly work in strong
winds.
•
Only perform assembly work in dry weather
conditions.
Observe the accident prevention regulations.
