It's not important anymore, because battery of  other Liebert ups  is wrong.
Liebert-esp2 driver works fine with my ups.

Thanks your answer.

I tested my ups with liebert-esp2 driver and use it ON Battery and if ups
status will be LB then shutdown the PC but if power back
then PC stay power off.
How can I configure nut that if power back then PC start automatic ?

Thanks your advice.
