Installation of a reactor

3.3 Installation of a reactor
When the inverter is connected near a large-capacity power transformer ( 1000 kVA) 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).
