These are typical values. The network topology and grounding, drive type, cable type, cable length, and motor type
have an effect on the phase-to-phase and phase-to-ground voltages of the motor. For motor dimensioning and
selection, refer to IEC 60034-18-41, IEC 60034-18-42 and IEC/TC 60034-25. For more information, contact ABB.
