Communications lost with UPS

Terminal.app told me the communications lost with UPS warming which I connect to my Mac Pro 2012.

I've been seen several commands and settings at /etc/apcupsd, though I can't figured it out yet.

macOS I've been using is Mojave and warning is started since I did security update. Mac Pro and UPS is connected via USB cable, though not update UPS utilities since I can't find the update for macOS.

Is there anyone who can help me?

Thanks in advance.
