11. Ensure that no voltage is present between L and PE at the AC terminal using a suitable
measuring device.
12. Actively discharge the DC link. For this purpose use,
for example, a 2-pole voltage detector that does not
have its own voltage source. Using the voltage
detector, conduct a measurement on the connection
screws of the terminal of the DC link connection
cable on the CON assembly until a value of 0 V is
displayed.
