Stopping the inverter via the display or by means of external control devices does not disconnect
the inverter from the line voltage.
When you press the Emergency Off button, this does not mean that the inverter is voltage-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.
Hazardous voltages can persist in the DC link (with current-source DC link inverters: in the
commutation capacitors) or from external or auxiliary power sources after the inverter 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.
