Installation Of A Reactor - Mitsubishi Electric FR-E700EX Instruction Manual

3.2

Installation of a reactor

When the drive unit is connected near a large-capacity power transformer (500kVA 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 an optional reactor (FR-HAL).
When connecting a single-phase 100V power input drive unit to a power transformer (50kVA or more), install an AC reactor
(FR-HAL) so that the performance is more reliable.
