Precondition
Switch off the converter power supply before replacing the fan unit.
WARNING
Electric shock as a result of a residual charge in power components
After the power supply has been switched off, it takes up to 5 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.
● Check the voltage at the converter connections before you replace the fan unit.
