7. Switch off the converter power supply.
8. Wait until all LEDs on the converter are dark.
Decide whether you want to withdraw the memory card from the converter:
• You remove the memory card:
⇒ The converter keeps its settings.
• You leave the memory card in the converter:
⇒ If the memory card still does not have a data backup of the converter settings, in step 9 the converter
writes its settings to the memory card.
⇒ If the memory card already includes a data backup, the converter imports the settings from the memory
card in step 9.
9. Switch on the converter power supply again.
10. If the firmware upgrade was successful, the converter LED RDY turns green after
several seconds.
If the memory card is still inserted, depending on the previous content of the
memory card, one of the two following cases has occurred:
• The memory card contains a data backup:
⇒ The converter has taken the settings from the memory card.
• There was no data backup on the memory card:
⇒ The converter has written its settings to the memory card.
You have upgraded the converter firmware.
