Static Bypass; Bypass Led; Auto Restart - Liebert UPS User Manual

STATIC BYPASS

The UPStation GXT provides an alternate path for utility power to the connected
load, in the unlikely event of a UPS malfunction. Should the UPS have an
overload, over temperature, or UPS failure condition, the UPS automatically
transfers the connected load to BYPASS providing the bypass voltage is within
specification. BYPASS operation is indicated by an alarm and an illuminated
BYPASS LED (other LED's may be illuminated to indicate any diagnosed
problem). The load may also be transferred to BYPASS using the control panel.
NOTE: The BYPASS power path does NOT protect the connected equipment
from disturbances on the utility supply and its range of operation is limited to +/-
17% of the nominal input supply voltage.
AUTO RE-START
Upon restoration of the utility AC power after a utility power outage and complete
battery discharge, the UPS will automatically restart and supply power to the
critical load and the battery charger will automatically recharge the battery.
