to comply. The SOLARWATT pricelist contains
matching cablesets, plugs, cables and installati
-
on 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 com
-
plied with. It is recommended to lay the cable
firmly so that they are not subjected to mecha-
nical loads. The cable and connector must not
exposed to moisture and will not rest on the
ground or floor.
Solar modules generate electrical energy on the front side during incidence of light. A
system with multiple solar modules can generate life-threatening voltages and electri-
cal currents. Do not touch the electrical connections or cable ends while the solar mo-
dule is exposed to light.
WARNING
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 permit-
ted up to the maximum system voltage as listed
in applicable data sheet. The maximum num
-
ber 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 allo-
wed to operate on a short circuit permanently.
The solar modules correspond to application
class II and can therefore be operated in sys
-
tems 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 the open cir-
cuit voltage UOC should be multiplied by a fac-
tor of up to 1.25, based on the lowest expected
ambient temperature for the given installation
location, to determine the rated voltage values
of components, the rated current values of con
-
ductors, the size of fuses and for dimensioning
control units connected to the solar modules.
Any type of soiling on the plug contacts befo
-
re or after installation (dust, moisture, aerosols
containing salt, etc.) has a negative influence on
the system function over the intended service
period. For this reason it is necessary to pay
particular attention to cleanliness during ins
-
tallation. The use of lubricants is not permitted.
Always protect unplugged connectors against
soiling of any type during transport, storage,
and during installation, as the connectors only
satisfy the requirements for their protection ca
-
tegory when plugged in. It is forbidden to open
the junction box or modify or remove the cable.
The cables must be laid so that mechanical
strain on the conductors and connections is ru
-
led out. Take into account the product-specific
length of the connection cable specified in the
