Anyone with PIWIS?

I had read that when the car is in service mode, the HV battery is disconnected for safety, which is why the power supply is required. Here is where I read that:

When PIWIS3 connects, you should be seeing a warning on the IC that the HV battery is energized. You might be talking about disabling the HV battery via a physical switch under the good (it even has a padlock lockout feature) which is done for safety when servicing HV components.
