During low mains voltage or a mains dropout, the drive continues until the DC-link voltage drops below the minimum stop level, which
corresponds typically to 15% below the lowest rated supply voltage of the drive. Power-up and full torque cannot be expected at mains
voltage lower than 10% below the lowest rated supply voltage of the drive.
The drive is suitable for use on a circuit capable of delivering up to 100 kA short-circuit current rating (SCCR) at 480/600 V.
