Stopping the inverter via the display or by means of external control devices does not discon-
nect the inverter from the line voltage.
When you press the EMERGENCY OFF button, this does not mean that the converter is volt-
age-free immediately.
Danger due to hazardous voltages when the cabinet doors are open.
These voltages can remain due to self-excitation if the connection to the motor is not removed.
Some surfaces in the inverter are hot during operation and for some time afterwards. Fans in
the inverter can continue to rotate after the unit has been switched off.
After disconnection of the line voltage, hazardous voltages can persist in the DC link (with
current-source DC link converters: in the commutation capacitors) or from external or auxiliary
power sources after the converter has been disconnected from the line voltage.
Depending on parameter settings and connection of external control devices, the inverter can
start up automatically when the line voltage is connected.
