2.3.2 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.
②
Never connect the phase advancing capacitor to the inverter output. If already installed, remove the
phase advancing capacitor clearly.
