7 General Specications
Line power supply (L1, L2, L3)
Supply voltage 380–480 V ±10%
Supply voltage 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. The stop level normally corresponds 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%
Maximum imbalance temporary between line power phases 3.0% of rated supply voltage
True power factor (λ) ≥0.9 nominal at rated load
Displacement power factor (cosφ) near unity (> 0.98)
Switching on input supply L1, L2, L3 (power-ups) maximum once/2 min.
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, 480/690 V
maximum.
