Footnotes for the preceding tables:
Note 1: The protection method conforms to JEM 1030.
Note 2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When using
other motors, care must be taken to prevent the rated motor current (50/60 Hz) from
exceeding the rated output current of the inverter.
Note 3: The output voltage decreases as the main supply voltage decreases (except when
using the AVR function). In any case, the output voltage cannot exceed the input
power supply voltage.
Note 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the
maximum allowable rotation speed.
Note 5: The braking resistor is not installed in the inverter. When your application requires a
high regenerative torque, use the optional regenerative braking unit and resistor (see
Chapter 5).
Note 6: The storage temperature refers to the short-term temperature during transport.
Note 7: Conforms to the test method specified in JIS C0911 (1984). For the model types
excluded in the standard specifications, contact your Hitachi sales representative.
Note 8: When using the inverter in a dust-prone area, we recommend the optional varnish
coating specification for the inverter.
Note 9: When using a remote operator keypad and cable, be sure to remove the RJ45 modular
interconnect from the inverter’s keypad port before connecting the cable.
Note 10: When using the inverter from 40° to 50°C ambient, the output current of the inverter
must be derated (see the next section on derating curves).
Note 11: NEMA 1 applies to inverter models up to 30kW (–300xxx). An optional wire-entry
conduit box is required for inverter models 37kW to 75kW (–370 to –750xxx) to
meet the NEMA 1 rating.
