4.3.1.4. Voltages
The Z001 main circuit card has the DC-link voltage after the input rectifier and several auxiliary voltages
made by the auxiliary PSU. Floating point voltage and remote control reference voltage need their own
ground points to get right values.
Note! Most voltages are in the primary side. Even touching the ground level may affect electric
shock because there is up to 120VDC between the ground and protective earth.
