Cabling - Sulfurcell SCG-HV-F Instructions D'installation

caBlING

Observe the safety instructions
for working with DC! Allow only
experts to carry out the works.
Do not disconnect energised
module jack connections!
In the event that plug-in connectors
must be opened up, the circuit must be
isolated beforehand at an appropriate
location with a load-break switch used
for this purpose. Disconnecting the
jack connections during the operation
can lead to non-quenchable arcing and
therefore to personal injury and mate-
rial damage.
The inverter must be connected
!
to the module fields properly.
Use only special solar cables and suit-
able plugs. In particular, the cables
used must be UV-resistant and appro-
priate for exterior use.
The electric connection between indi-
vidual modules and to the inverter
must be made with plug connections of
the same type that are pre-mounted on
the modules. While doing so, keep in
mind secure and gap-free connection
of the plug connections.
In order to reduce over-voltages due to
lightning bolts, the surface of the con-
ductor loops must be as small as pos-
sible; avoid conductor loops with large
areas.
Cable cross-sections and lengths
should be selected to ensure that the
outlet loss is less than 1 %. The mini-
mum permissible cable cross-section
is 4 mm².
