separately to upgrade. For detailed steps, please refer to the C2000 simulator instruction.

maintenance bypass mode.
Turn on the UPS with utility. Open the serial program software Prg2800_33.exe
Note:
a) When burning is finished, the other DSP cannot be burned until the DSP buzz. ( after burning INV,
about 5S later, the next burning can be performed. When finish burning the REC, the next burning can
be executed after about 20s).
b) If it fails during the REC burning, it will show “ Program was
unsuccessful”. Switch off the UPS and then restart, click “Update” to re-burn.
c) If it fails during the INV burning, it will show “Program was
unsuccessful”. Switch off the UPS and then restart, modify the ID number to 1 in the software. Close the

an infinite loop. Restart the UPS and Prg2800_33 and check if the communication connection is ok.
Then re-burn can be operated. If it is the REC burning, please refer to the item b, if INV burning, please
refer to item c.
