3.1.5.2
Star-delta connection of the motor
V20 single-phase inverter requests a
1AC 230V
connection in
input
.
The
output
connection is
230V 3AC
and is must be carried out consistently with the motor connection, con-
sidering that the supply voltage will never exceed the input voltage
For instance, select delta connection if either a 230 / 400 V motor on a 400 V inverter or a 120 / 230 V motor
on a 230 V inverter is supposed to operate at 87 Hz instead of 50 Hz.
