Hello : Some news ... I poweroff my ups during one day without improvement I tried to connect my ups, I had the same error
This morning, I tried to simulate electric failure on UPS until the battery are empty The UPS has stopped When I poweroff the ups, all is good Perhaps, it's the shutdown procedure ? no ?
