Line Synchronization
When both the “LINE POWER” and “LINE FAILURE” LEDs are ON, the UPS is
synchronizing its output frequency to the utility input prior to resuming AC line
operation. Synchronization takes approximately 15 seconds. If the line frequency
(generator frequency) is out of tolerance, the UPS can not synchronize to it, and stays
in the inverter mode.
Line Failure (AC Input Out of Tolerance)
Whenever AC line voltage becomes unacceptably high or low (+10 % /
25%), or the line frequency exceeds + 3%, the "LINE PRESENT" LED
flashes and the "LINE FAILURE" LED lights indicating the UPS is
running on backup power.
NOTE: High generator THD can also cause this condition.
Line Failure Operation
Whenever a utility power outage occurs, the UPS initiates LINE FAILURE
operation without interruption of output power. The amber “LINE FAILURE” LED lights
to indicate that the UPS is running on backup power.

Line Present Operation
The green “LINE PRESENT” LED indicates that the UPS is running on AC line
(utility / mains) power.
