Note: The power factor may be slightly less.
When the inverter is connected near a large-
capacity power supply transformer (500kVA
or more, wiring length 10m maximum) or
there is power capacitor switch-over,
excessive peak currents may flow into the
power input circuit and damage the converter
circuit. In such a case, the power supply
improving reactor (FR-BEL or FR-BAL) must
be installed.
