5 General Specifications
Mains supply (L1, L2, L3):
Supply voltage 380-500 V ±10%
Supply voltage 525-690 V ±10%
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converters continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the drive's lowest rated supply voltage. Power-up and
full torque cannot be expected at mains voltage lower than 10% below the frequency converter’s lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Max. imbalance temporary between mains 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) maximum 1 time/2 min.
Environment according to EN60664-1 over-voltage category III/pollution degree 2
