I would guess one of Something is flaky and the power is not as good as it seems, or the wiring from power strip where you are measursing to UPS input is off. I would definitely remove and re-seat everything you can. The circuitry that senses voltage is off. The neutral is open and then all bets are off. Did you measure hot to neutral, hot to ground, neutral to ground? You say 230 and I'm guessing this is in a place with 230V outlets. (In the US we have 125V with neutral and 250V phase to 180-out-of-phase phase, for "single phase" service.) So actually, check the neutral inside the equipment. Power it all down and unplug and be super careful as UPS devices have power inside when they are off and unplugged. _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
