> event 1 is always “Site wiring” and every other event is always “None”, even though there have been multiple power events, and there is no site wiring issue

Some UPS:es are adamant about wanting live and neutral on specific pins on the power plug and will throw that error message if they're swapped.

If it's a reversible power plug, flip it around. If the power plug can only be connected in one orientation the outlet is likely incorrectly installed (which is not all that uncommon, as 99.99% of stuff will work perfectly fine with live and neutral swapped).
