For more information on “System load” and “Line chokes” refer to
section 6.1.
If you want to know more about “harmonics and input rectifiers” we can
recommend the book entitled “Oberwellen” ("Harmonics" - German) by
Albert Kloss - see the bibliography and source reference.
3.2.3 General points
on the mains
connection
The minimum cross-section of the mains power cable is based on the
local provisions (to VDE 0100 Part 523, VDE 0298 Part 4), the ambient
temperature and the specified rated current of the inverter.
