3-8
AC Power Input Type
SV5000iV5-4
Note: AC220V (50/60 Hz) must be supplied to FAN1 and FAN2 because 500kW-4
type of inverter has an AC fan of 220V internally. If not use AC220V power,
the inverter is not operated because of ‘FAN PWR’ until the trip is released
after inputting of AC220V. The order of power supply is described as below.
(The order of power on: 220VAC for fan
Main power source of 3-phase AC input
Run)
(The order of power off: Stop
Main power source of 3-phase AC input
220VAC for fan)
Note 1) It is used when inverter control circuit is energized from auxiliary power
source (220 VAC) without main power supply. Use insulated transformer to
separate from main power supply. (Transformer capacity: above 100VA
recommended)
