6.2 General Specifications
Mains supply (L1, L2, L3)
Supply Terminals
L1, L2, L3
Supply voltage
380-480 V:-15% (-25%)
1)
to +10%
1) The frequency converter can run at -25% input voltage with reduced performance. The maximum output power of the
frequency converter is 75% in case of -25% input voltage and 85% in case of -15% input voltage.
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the frequency converter's lowest rated supply voltage.
Full torque cannot be expected at mains voltage lower than 10% below the frequency converter's lowest rated supply voltage.
