The AC-input power is out of tolerances, LED 16 goes ON.
During operation on battery power, the buzzer beeps every ten seconds.
The equipment connected to the UPS is supplied by the battery.
Threshold for the low-battery warning
When the threshold is reached, the buzzer beeps every three seconds.
The low-battery warning threshold can be set by the user, with the “UPS
Driver” software.
There is very little remaining battery backup time. Close all appli-
cations because UPS automatic shutdown is imminent.
When the battery reaches the end of its backup time, the UPS shuts
