Installation of power factor improving reactor
3.2 Installation of power factor improving reactor
When the drive unit is connected near a large-capacity power transformer (500kVA or more) or when a power capacitor is to
be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent
this, always install an optional AC reactor (FR-HAL).
