Installation of a reactor
When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor
correction 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).
