Removing functional grounding connections from the converter
Precondition
Switch off the converter power supply before removing the functional grounding.
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to five minutes until the capacitors
in the converter have discharged so that the residual charge is at a non-hazardous level.
Therefore, touching the converter immediately after powering off can result in electric
shock due to residual charge in the power components.
