[Nut-upsuser] MGE Pulsar evolution 2200

[Sabine GOUDARD]

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 ?


Thanks for your help
