2.3 Cabling
Connect the number of modules that corresponds to the voltage specifications of the devices used in the
system. The modules (in accordance with protection class II) must not be operated with a higher voltage
than the permitted system voltage. The specifications can be found in the datasheet of the modules or in the
datasheet of the relevant inverters. Please ensure that the cables are installed and fixed in such a way that,
in particular, the plug-in connections do not lie in a water-carrying plane.
The specified protection classes are to observed, however, the minimum compliance required is IP65.
Ensure a gapless connection when connecting the plug-in connectors.
Disconnecting the module connections during operation can result in light arcs (break sparks) and
therefore in a hazard for people and equipment. Do not insert any objects into the plugs and sockets!
For a series connection, only modules with the same current rating should be used, and for a parallel
connection, only modules with the same voltage rating should be used.
Suitable overcurrent protection measures (e.g. string cut-out) are required for the parallel connection of the
modules. It must be ensured that the specified capacity regarding the return current, IR, of 16 A will not be
exceeded.
In a shaded system the modules or module strings should be connected in parallel.
Only use special solar cables and suitable plugs. Attach the cables to the mounting system using UV-
resistant cable ties and avoid exposing the cables to direct sunlight.
