Installation guide for solar inverters RPI M6A M8A M10A EU V5 EN 2022-08-15
ATTENTION
Incorrectly wired AC plug.
Incorrect wiring can destroy the inverter.
► Pay attention to the correct phase
assignments when connecting the AC
cable to the AC plug.
The inverter can be connected to 3-phase
grids without neutral conductors (3P3W, 3
phases + PE) and 3-phase grids with neu-
tral conductors (3P4W, 3 phases + N + PE).
► If the inverter is connected to a grid
without a neutral conductor, the AC con-
nection type must be changed using the
display to 3P3W after commissioning,
see ”AC connection type”, page 23.
