Overvoltage category III/pollution degree 2
1) The unit is suitable for use on a circuit capable of delivering not more than 85000 RMS symmetrical Amperes, 480/600 V.
2) Mains voltage low/mains voltage drop-out:
During low mains voltage, the drive module continues until the DC-link voltage drops below the minimum stop level, which
corresponds typically to 15% below the lowest rated supply voltage. Power-up and full torque cannot be expected at mains
voltage lower than 10% below the lowest rated supply voltage. The drive module trips for a detected mains drop-out.
