Switching on the input
Switching on the input depends on the mains voltage
in question and on whether Quick discharge of the in-
termediate capacitor has been selected. The table
below states the waiting time between cut-ins.

Acoustic noise
The acoustic interference from the frequency convert-
er comes from two sources:
1.
DC intermediate circuit coils.
2.
Integral fan.
