A filtering network for the supply voltages is located next to their connectors, the converter circuits of the individual channels
are protected by additional filters.
The high-voltage filters are housed in individual metal enclosures to shield even minimal interference radiation.
3.4 Floating HV-outputs
Both HV outputs are related to the same ground HV-0V (HV-GND), provided on the outer connector (screen of HV cable) of
SHV connectors. The channels can be switched independently in polarity, the output voltages, related to HV-0V (HV-GND),
are also independently controlled.
The SHV connectors are mounted isolated to chassis (PE) in order to have a floating HV-0V.
If the floating voltage is increased above 47V a suppressor diode connects HV-0V to PE (chassis) to avoid dangerous
voltages between HV-0V and PE/chassis.
