Danfoss vlt FC 102 Installation Guide

7.2 Mains Supply to Drive Module
Mains supply
1)
Supply terminals R/91, S/92, T/93
Supply voltage
2)
380–480, 500 V 690 V, ±10%, 525–690 V ±10%
Supply frequency 50/60 Hz ±5%
Maximum temporary imbalance between mains phases 3.0% of rated supply voltage
True power factor (λ) ≥0.98 nominal at rated load
Displacement power factor (cos Φ) (Approximately 1)
Switching on input supply L1, L2, L3 Maximum 1 time per 2 minutes
Environment according to EN 60664-1 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.
7.3 Motor Output and Motor Data
