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 circuit voltage UOC should be multiplied by a factor 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 conductors, the size of
fuses and for dimensioning control units connected to the solar modules.
Any type of soiling on the plug contacts before or after installation (dust, moisture, aero-
sols containing salt, etc.) has a negative influence on the system function over the inten-
ded service period. For this reason it is necessary to pay particular attention to clean-
liness during installation. 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 category when plug-
ged in. It is forbidden to open the junction box or modify or remove the cable or frame.
The cables must be laid so that mechanical strain on the conductors and connections is
ruled out. Take into account the product-specific length of the connection cable specified
in the relevant data sheets at solarwatt.com.
WARNING
The plug contacts must not be connected or disconnected under load. Failure
to comply with this warning could result in DEATH!
Potential equalization of the solar gene-
rator is prepared in the factory and is re-
commended. It can be carried out using
the existing punchings for potential equa-
lization on the long sides of the frame (see
figure) or suitable clamps with integrated
grounding pins in accordance with the valid
local regulations.
NOTE
It is advisable to install lightening protection in exposed locations. The solar mo-
dules should be incorporated in existing lightening protection equipment. For this,
take into account the relevant valid regulations (e.g. EN 62305 and VDE 100).
