7.8 Connecting to the grid (AC)
The inverter can be connected to 3-phase grids
with no neutral conductor (3P3W, 3
PE) and 3-phase grids with a neutral conductor
(3P4W, 3 N + PE).
► If the inverter is connected to a grid without
neutral conductors, the AC connection type
must be changed to 3P3W on the display
after commissioning, see “9.17 AC connec-
tion type”, page 104.
