I have 3 APC smart ups 1000. Last night when nobody was working, I received notifications:
"UPS: Compensating for a high input voltage.
Name: Unknown
Location: unknown

serial number:99999
date:mm/dd/yyyy
time: hh:mm:ss
Code: 0x010D
Warning Events-UPS: Compensating for a high input voltage."
This occurred in the middle of the night and didn't stop unitl early in the morning.
The rated output is at 120 VAC
The high transfer voltage is at 127 VAC
Is there anything that caused this or I should be concerned about?
