Installation and Operating Instructions for LOHER DYNAVERT I Series 7
Operating Instructions, 10/2022, 4BS0745-002
Stopping the converter via the display or by means of external control devices does not discon-
nect the converter from the line voltage.
When you press the EMERGENCY OFF button, this does not mean that the converter 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 converter are hot during operation and for some time afterwards. Fans in
the converter 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 cur-
rent-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 the parameterization and connection of external control devices, the converter
can start up automatically when the line voltage is connected.
