When the mains power capacity is > 500kVA or
when the drive is preceded by a capacitor bank,
the instantaneous peaks voltages and current may
AC reactor destroy the drive. In that case it is recommended
(input terminal) to install an AC input reactor which will also
improve the power factor and harmonics. The
cable between reactor and drive should be < 10m.
Please refer to Chapter 7-4.
