-accessories need pass the UL467 standard
test and UL E34440/E6207 test.

-For fully grounding, grounding hardware should
penetrate the anodic oxidation layer of frame.
-Recommended 10-12 AWG bare copper groun-
ding wire.
MODULE WIRING
-All wiring should be performed, by qualified
installers, in accordance with the local codes
and regulations.
-Modules can be connected in series to in-
crease the operating voltage by plugging the
positive plug of one module into the negative
socket of the next. Before connecting modules
always ensure that the contacts are corrosion
free, clean and dry.
-Product can be irreparably damaged if an array
string is connected in reverse polarity to ano-
ther. Always verify the voltage and polarity of
each individual string before making a parallel
connection. If you measure a reversed polarity
or a difference of more than 10V between
strings then check the string configuration
before makingthe connection.
-Taurus Renovables Solar modules are provi-
ded with stranded copper cables with a cross
sectional area of 4mm² which are rated for
1500Vdc, 90°C and are UV resistant. All other
cables used to connect the DC system should
have a similar (or better) specification. Taurus
Renovables Solar recommend that all cables
are run in appropriate conduits and sited away
from areas prone to water collection.
-The maximum voltage of the system must
be less than the maximum certified voltage
(1500V typically) and the maximum input vol-
tage of the inverter and of the other electrical
devices installed in the system. To ensure that
this is the case, the open circuit voltage of
the array string needs to be calculated at the
lowest expected ambient temperature for the
location. This can be done using the following
formula.
-System voltage N × Voc × 1 TCvoc × 25 Tmin
NOTES:
-N: No modules in series
-Voc: Open circuit voltage of each module (refer
to product label or data sheet)
-TCvoc: Thermal coefficient of open circuit vol-
tage for the module (refer to table (add))
-Tmin: Minimum ambient temperature
-The minimum and maximum outer diameters of
the cable are 5 to 7mm2.
-For field connections, use at least 4 mm2 cop-
per wires insulated for a minimum of 90°C and
sunlight resistance with insulation designated
as PV Wire.
-The minimum bending radius cables should be
43mm.

ELECTRICAL
CONFIGURATION
-Photovoltaic (electric) systems operate au-
tomatically and require very little day-to-day
supervision. The solar array generates DC
electricity whenever light falls on it similarly
the inverter automatically turns ON as soon as
there is sufficient energy from the solar array
to efficiently convert this into grid quality AC
power.
CAUTION:
-The module is rated to operate at potentially
lethal DC voltages which have the potential can
cause severe electrical shock, arcing and fire
hazards. Whilst some solar modules, manufac-
tured by Taurus Renovables Solar, are certified
to operate up to 1500V dc always check the
module label to confirm the actual rating of
your product before making connections.
-Always use a suitably rated isolator (DC switch)
to interrupt the current flow before disconnec-
ting the connectors.
FUSING
-When fuses are fitted they should be rated for
the maximum DC voltage and connected in
each, non-grounded pole of the array (i.e. if
the system is not grounded then fuses should
be connected in both the positive and negative
poles).
-The maximum rating of a fuse connected in se-
ries with an array string is typically 20A but the
actual module specific rating can be found on
the product label and in the product datasheet.
-This fuse rating value also corresponds to the
maximum reverse current that a module can
withstand (when one string is shaded then the
other parallel strings of modules will be loaded
by the shaded string and current will flow) and
therefore impacts the number of strings in
parallel. Parallel module configurations: fuse
rating/Isc.
