4.3 General Specifications
Line Power Supply
Supply terminals (6-Pulse) L1, L2, L3
Supply terminals (12-Pulse) L1-1, L2-1, L3-1, L1-2, L2-2, L3-2
Supply voltage 380–500 V ±10%
Supply voltage FC 302: 525–690 V ±10%
AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage
drops below the minimum stop level, which corresponds typically to 15% below the adjustable frequency drive's lowest rated
supply voltage. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the adjustable frequency
drive's lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Max. temporary imbalance between line phases 3.0% of rated supply voltage
True power factor (λ) ≥0.9 nominal at rated load
Displacement Power Factor (cos ϕ) near unity (>0.98)
Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW Maximum 1 time/2 min.
Environment according to EN60664-1 Overvoltage category III/pollution degree 2
