8 General Specifications

Mains supply (L1, L2, L3):
Supply voltage
Mains voltage low / mains drop-out:
During low mains voltage or a mains drop-out, the FC continues until the intermediate circuit voltage drops below the minimum stop level, which
corresponds typically to 15% below the FC's lowest rated supply voltage. Power-up and full torque cannot be expected at mains voltage lower than
10% below the FC's lowest rated supply voltage.
