Mains choke, required for controllers <= 11 kW?

Question:

Is it necessary to use a mains choke for controllers of the 8400 series (<= 11 kW)?

Answer:

No, it is not. Controllers of the 8400 series (<= 11 kW) can be operated without mains choke because the mains input and the DC-bus have been dimensioned for the higher (current) load.
