Module installation and operation should be performed by qualified personnel only. Children should not be allowed near the solar electric
installation.
If not otherwise specified, it is recommended that requirements of the local, national or regional electrical codes be followed.
Use module for its intended function only.
Do not disassemble the module, or remove any part or label installed by manufacturer.
INSTALLATION
Series and parallel wiring
Modules can be wired in series to increase voltage. Connect wire from the positive terminal of one module to the negative terminal of the next module.
The first illustration shows four modules connected in series. Installer should consider the maximum allowed system voltage in case of connecting
modules in series. Take also care of connecting in series strictly only modules of the same type (the current at the maximum power point must be the
same).
Connect modules in parallel to increase current. Connect wires from the positive terminal of one module to the positive terminal of the next module. The
second illustration shows four modules connected in parallel.
It is recommended that paralleling modules be performed using an external junction box. Installer should also keep in its mind that the current values are
additive in parallel connection and the common wire cross section must be chosen according to local regulations and standards. When cabling a system
of several modules installer should ensure that the voltage drop on the main conductor does not exceed 2 % of the nominal voltage.
There are many types of mounting system used to install Korax Solar modules. The mounting structure must withstand all snow and wind forces. Module
mounting holes are provided for easy installation and proper mechanical loading. Contact your local dealer for information regarding mounting structures
and special mounting profiles for modules. This illustration shows one possibility to mounting some modules.
Grounding
Module frames should be connected to an earth for safety and protection from lighting. Korax Solar modules have a hole on the frame marked with
symbol for connecting the earthing cable. If the support structure is a conductor, the metallic contact between the frame and the structure must be
ensured during the assembly of the modules. In that case the supporting structure must earthed according to the local regulations. Should the support
structure made of non-conducting material it is recommended that the earth conductors from the individual modules connected to a common earthing
terminal (bus conductor) so that removal of any module does not interrupt the earth connection of the remaining modules.
Air Circulation
Sufficient clearance between the module frame and the mounting surface is required to allow cooling air to circulate around the back of the module. This
also allows any condensation or moisture to dissipate.
