Switching on the input
Switching on the input depends on the AC line 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 adjustable frequen-
cy drive comes from two sources:
1. DC intermediate circuit coils.
2. Integral fan.
