8.1.1 Power Rating

Grid conditions:
Supply voltage
Mains voltage low / mains drop-out:
During low mains voltage or a mains drop-out, the Filter continues until the intermediate circuit voltage drops below the
minimum stop level, which corresponds typically to 15% below the filter lowest rated supply voltage. Full compensation cannot
be expected at mains voltage lower than 10% below the filter lowest rated supply voltage. If mains voltage exceed the filter
highest rated voltage the filter continues to work but harmonic mitigation performance is reduced. Filter will not cut out until
main voltages exceed 580V.
