8.2 Mains Supply
Mains 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 200–240 V ±10%
Supply voltage FC 301: 380–480 V/FC 302: 380–500 V ±10%
Supply voltage FC 302: 525–600 V ±10%
Supply voltage FC 302: 525–690 V ±10%
Mains voltage low/mains dropout:
During low mains voltage or a mains dropout, the frequency converter continues until the DC-link voltage drops below the
minimum stop level, which corresponds typically to 15% below the frequency converter'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%
Maximum 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) ≤7.5 kW (10 hp) Maximum twice per minute.
Switching on input supply L1, L2, L3 (power-ups) 11–75 kW (15–101 hp) Maximum once per minute.
Switching on input supply L1, L2, L3 (power-ups) ≥90 kW (121 hp) Maximum once per 2 minutes.
Environment according to EN60664-1 Overvoltage category III/pollution degree 2
The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes,
240/500/600/690 V maximum.
