Installation of a reactor

When the inverter is connected near a large-capacity power transformer (500 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 AC reactor (FR-HAL), which is available as an option.
