Switch off the inverter power supply.
Wait until all LEDs on the inverter are dark.
Insert the card with the matching firmware into the in-
verter slot until it latches into place.
Switch on the inverter power supply again.
The inverter transfers the firmware from the memory
card into its memory.
The transfer takes approximately 5 ... 10 minutes.
While data is being transferred, the LED RDY on the
inverter stays red. The LED BF flashes orange with a
variable frequency.
