ELECTRICAL CONNECTION AND POTENTIAL EQUALIZATION
The solar modules are equipped at the factory with high-quality junction boxes with a
specific connector face. To connect the modules a jumper cable is required. The connecti-
on of the string line has to be done with identical connectors manufacture and type as to
the module connecting cable. To be able to ensure this the module connector at the be-
ginning and the end of the string may be removed and replaced (More information in the
download area at www.solarwatt.com). The allowed cross-section and outer-diameter of
the cable and instruction of the manufacturer have to comply. The SOLARWATT pricelist
contains matching cablesets, plugs, cables and installation accessories. When connecting
the modules, ensure that the plugs engage with an audible click. The common bending
radii of at least 5 times the outer cable diameter must be complied with. It is recommen-
ded to lay the cable firmly so that they are not subjected to mechanical loads. The cable
and connector must not exposed to moisture and will not rest on the ground or floor.
WARNING
Solar modules generate electrical energy on the front side during incidence of
light. A system with multiple solar modules can generate life-threatening vol-
tages and electrical currents. Do not touch the electrical connections or cable
ends while the solar module is exposed to light.
To ensure safety and compliance with the technical data of the products, only original
tools of the manufacturer may be used in the self-assembly of solar cables.
Connection of modules in series is only permitted up to the maximum system voltage as
listed in applicable data sheet. The maximum number of solar modules installed parallel
without string fuse is two. Please comply with the value specified in the data sheet for
reverse current feed and only use standardized photovoltaic cables (recommendation: at
least 4 mm² cable cross-section). The modules must not be allowed to operate on a short
circuit permanently.
The solar modules correspond to application class II and can therefore be operated in
systems with dangerous DC voltages (larger than 120 VDC in accordance with IEC 61730).
Solar modules in this application class can be used in systems with unrestricted access,
the relevant regulations must be complied with. Solarwatt solar modules qualified within
this application class in accordance with IEC 61730 fulfill the requirements of protection
rating II with correct electrical installation.
Under normal installation conditions, a solar module can deliver a higher current and/
or higher voltage than under standardized test conditions. Consequently, the specified
values on the solar module for short circuit current ISC should be multiplied by 1.25 and
