Delta Electronics VFD110CH23A-21 [76/638] When the ac motor drive is connected directly to a large capacity power transformer 600kva or above or when a phase lead capacitor is switched excess peak currents may occur in the power input circuit due to the load changes and the converter section may be damaged to avoid this it is recommend using a serial connected ac input reactor 6 at the ac motor drive mains input side to reduce the current and improve the input power efficiency

When the AC Motor Drive is connected directly to a large-capacity power transformer
(600kVA or above) or when a phase lead capacitor is switched, excess peak currents may
occur in the power input circuit due to the load changes and the converter section may be
damaged. To avoid this, it is recommend using a serial connected AC input reactor (6%) at
the AC Motor Drive mains input side to reduce the current and improve the input power
efficiency.
