Terminal Symbol
Function Description
L, N
Terminals of single phase AC input
U, V, W
Motor wiring terminal
PE/
Terminals of ground
R, S, T
Terminals of 3 phase AC input

Reserved external terminals for braking DC reactors
(-)
Output terminals for minus DC bus voltage
Notice:
it can’t wire to “U” “V” “W” terminal arbitrarily when connect it with
single phase motor. It need to take away the capacitance as figure 4.1.13 diagram, and
wire according to the figure 4.1.14 diagram.
Notice that the “L” “N” in picture is not the same “L” “N” as the terminal of inverter
