Installation Of A Reactor - Mitsubishi Electric FR-A720-0.4K Instruction Manual

Installation of a reactor

3.2 Installation of a reactor

When the inverter is connected near a large-capacity power transformer (1000kVA 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 the optional AC reactor (FR-HAL)

supply
* When connecting the FR-HEL to the 55K or less, remove the jumper across terminals P/+ - P1. For the 75K or more, a DC reactor
is supplied. Always install the reactor.
REMARKS
The wiring length between the FR-HEL and inverter should be 5m maximum and minimized. Use the same wire size as that of the
power supply wire (R/L1, S/L2, T/L3). (Refer to page 21)
