7.3 Replacing SINAMICS G120C inverters or SIMATIC ET 200pro FC-2 converters
Replacing the inverter with data backup in the operator panel (BOP-2 or IOP)
Procedure
To replace the inverter, proceed as follows:
1. Disconnect the line voltage to the inverter and (if installed) the external 24 V supply or the
voltage for the digital outputs of the inverter.
2. Remove the connecting cables of the inverter.
3. Remove the defective inverter.
4. Install the new inverter.
5. Connect all of the cables to the inverter.
6. Reconnect the line voltage, and (if being used) the external 24 V supply or the voltage for
the digital outputs of the inverter.
7. Attach the operator panel to the inverter.
8. Transfer the settings from the operator panel to the inverter, e.g. via menu "EXTRAS" -
"FROM BOP" in the BOP-2.
9. Wait until the transfer is complete.
The inverter signals faults after the download. Ignore these faults, as they will be
automatically acknowledged by the following steps.
10.Switch off the inverter power supply.
11.Wait until all LEDs on the inverter are dark.
12.Switch on the inverter power supply again (power on reset).
13.Perform a reduced acceptance test, see the section Reduced acceptance test after
component replacement (Page 266).
You have replaced the inverter and transferred the safety function settings from the operator
panel to the new inverter.
