3.3.3 Cautions to be required for wiring to power circuit terminal
①
Connect terminals (R, S and T) to 3 phase input power supply after checking
inverter nameplate attached on the inverter. Never connect terminals (U, V
and W) to 3 phase input power supply. It results in lethal damage to the
inverter.
