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-

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. Short-circuit current protec-
