Yes basically you cant coz they did not give it to everyone even in the manufacturing side or service center. They just give it to selected people coz its very confidential.

Inverter 12V to 230v not working


Could be the devices, the inverter, the up converter,or the micro.

Throw it away and buy a new one, as this will be cheaper and easier.

UPS devices are very complicated with lots of related circuits logic etc.

These units are not made to last, recover the batteries or recyle the whole thing.

U.p,s not comming on


when the battery dries out over time, it may fail. replacements are available. ups units are alot cheaper than they used to be. also some units. have fuses inside on the circuit board. i have had an old apc ups that started smoking one day after putting new battery! so take that into consideration. i hope this is helps,good luck!
