Overvoltage category III/pollution degree 2
1
Mains voltage low/mains dropout: During low mains voltage or a mains dropout, the drive continues until the DC-link voltage drops below the
minimum stop level, which typically corresponds to 15% below the drive's lowest rated supply voltage. Power-up and full torque cannot be expec-
ted at mains voltage lower than 10% below the drive's lowest rated supply voltage.

The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 240/500/600 V maximum.
