Wiring Of The Main Circuit - Mitsubishi Electric FREQROL HC Instruction Manual

1.3.3 Wiring of the main circuit

• The high power factor converter (FR-HC) is a high-power factor, low-noise inverter option unit designed for
use with the transistorized inverters (FR-HC compatible models) in accordance with the harmonic
suppression guidelines published by Ministry of Economy Trade and Industry (formerly Ministry of
International, Trade and Industry). This high power factor converter is used for the suppression of
harmonics to an input power supply.
• To comply with the harmonic suppression guidelines published by the MITI, the system needs to be
configured as indicated and make sure that terminals P and N are sacurely connected to terminals P and N
of the inverter. An incorrect connection will cause the high power factor converter to display an alarm or to
be faulty or damaged.
• Refer to the inverter instruction manual on how to wire the system to suppress harmonics to the input
power supply. Especially note the wiring distance and cable size.
(1) Cable, Crimping terminals etc.
