Installation Of Reactor - Mitsubishi Electric FR-V500 Instruction Manual

1.6.3

Installation of reactor

When the inverter is connected near a large-capacity power transformer (1000kVA or more and wiring length 10m
max.) 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 the DC reactor or AC reactor (FR-HEL/BEL or
FR-HAL/BAL).
