After the power supply has been switched o, it takes up to ve 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 o can result in electric shock
due to residual charge in the power components.
• Check the voltage at the converter connections before you remove the functional
grounding.
