10.6.6 Removing HF capacitors
If a PWM modulated rectifier from another manufacturer is connected to the same input
transformer, the capacitors must be removed! Otherwise the capacitors must not be removed.
Figure 92 and Figure 93 have a red marking on the lead that has to be removed from each capacitor
if the interference suppression capacitors are not to be used. Removing the lead disconnects the
capacitors from ground potential.
