3.2.4 Overview of terminal assignment
Using examples, this overview indicates which system parts can be
connected for all terminals in the module. The components (such as VS1
and VS3) identified with * in the system, are possible alternatives.
Depending on how the module is used, one of the components is
connected to the "VS1/PS2/PS3" terminal.

More complex solar systems can be realised in combination with a
second solar module. Terminal assignments, which deviate from the
terminal overview, are possible with this option ( connection diagrams
with system schematics).
