11 Optional Device Functions
11.1 Additional function 24 V Stand-by Power Supply
General
The additional function standby allows the control electronics to operate
without any line supply voltage connected to the converter. A 24 V DC
control power supply voltage is required.
This additional function offers the following advantages:
•
Data sets can be parameterized, read and written into although the
converter is not connected to the line supply voltage
•
Data sets can be parameterized, read and written into although no DC
link voltage is connected to the inverter
•
Continued operation of field buses with the power supply disconnected
WARNING
Damage due to overload of the component!
⇒
To prevent ground loops, we recommend that the
24 V Standby power supply voltage be applied to
X83 in a floating manner.
WARNING
Damage due to overload of the component!
⇒
If the floating method is not used, X83 is not
protected from reverse polarity.
