I installed the upsmon software on my PC, but I get this error message:

How do I connect to the ups, because when I am in Suse about 5 minutes the ups starts beeping. The only way I can stop this is if I shutdown the PC and pull out the connection cable and start the PC again.

Or, how can I turn UPS monitoring off completely?

Thanks in advance.
