This NMC 2 is on 5.X.X firmware as such may require you to stage update to 6.X.X before going to v7.2.2.
Contact APC Technical Support to request any version of v6.X.X NMC 2 firmware for what ever platform such as Smart-UPS / Symmetra single phase.
Another option is to manually install the three files as outlined in the NMC FAQ:
