my 2Kva UPS just got burned too for no reason :/
I am not familiar with this model but you need to disassemble it and hope there is a high current fuse that popped,if it isn't designed with reverse polarity protection it might be real bad you may have burned the internal reverse diodes in the mosfets voltage regulators for main circuit or some passive resistors along the way
