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 qualifi-
cations and contain safety-relevant instructions for the as-
sembly, connection and maintenance of the solar modules.
IMPORTANT
The solar modules may only be mounted by personnel with
electro-technical qualifications. Appropriately qualified techni-
cians 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 infor-
mation. After the module has been installed, hand over these
instructions to the operator of the solar modules for safekeep-
ing.

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.

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 dis-
charging 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.
