400 V units: 380...415 V AC 3-phase ± 10%. This is indicated in the type designation
label as typical input voltage level (3~ 400 V AC).
500 V units: 380...500 V AC 3-phase ± 10%. This is indicated in the type designation
label as typical input voltage levels (3~ 400/480/500 V AC).
690 V units: 525...690 V AC 3-phase ± 10% (525...600 V AC ± 10% in UL/CSA
installations, or corner-grounded TN systems). This is indicated in the type desig-
nation label as typical input voltage levels (3~ 525/600/690 V AC).
TN (grounded) and IT (ungrounded) systems
50/60 Hz, variation ± 5% of nominal frequency
Max. ± 3% of nominal phase-to-phase input voltage
Supply units with the ABB-defined main switch-disconnector and fuses:
•Rated peak withstand current I
•Rated short-time withstand current I
Supply units with ABB-defined main circuit breaker and fuses:
•Rated peak withstand current I
•Rated short-time withstand current I
The drive is suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes at 600 V maximum when the input cable is
protected with class T fuses.

THD = Total Harmonic Distortion (THD). The voltage THD depends on the short-
circuit ratio (R ). The spectrum of the distortion also contains interharmonics.
