SOLARWATT solar modules are equipped at the factory with
high-quality solar cables and reverse-polarity protected,
shock-proof plug connectors. No others may be used. When
connecting the modules, ensure that the plugs engage with
an audible click.
To ensure that the products are safe and comply with the tech-
nical data, only genuine tools from the relevant manufacturer
may be used when self-assembling solar cables. The solar ca-
bles must be compatible with the module plug system of the
relevant manufacturer.
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data
sheet. The recommended maximum number of solar modules
installed parallel is three (without string fuse). Please com-
ply with the value specified in the data sheet for reverse-cur-
rent feed and only use standardized photovoltaic cables (rec-
ommendation: at least 4 mm² cable cross-section).
The solar modules correspond to application class A and can
therefore be operated in systems with dangerous DC voltages
(larger than 120 V
DC
in accordance with IEC 61730) and servic-
es. Solar modules in this application class can be used in sys-
tems 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.
WARning
The plug contacts must not be con-
nected or disconnected under load.
Failure to comply with this warning
could result in DEATH!
nOte
It is advisable to install lightening protection in exposed locations. The solar modules
should be incorporated in existing lightening protection equipment. For this, take into
account the relevant valid regulations (e.g. EN 62305 and VDE 100).
