    AC power to regulated DC power for use by the inverter, while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the utility power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the utility is reduced.

    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.

    STABILIZERS / LEVELING FEET When the UPS is located in its final position before or after wiring, it is necessary to fit stabilizer brackets and, if necessary, adjust the leveling feet. If the UPS is wired using a rigid wiring system, then movement of the UPS must be prevented by winding down the 4 leveling feet under the UPS as shown below.

    Manual Battery Test Output OFF / Bypass Fault Indicator (Red) The Fault indicator is illuminated if the UPS has detected a problem. Also, one or more of the load/battery level indicators may be illuminated (refer to Troubleshooting Guide). BYPASS Indicator (Amber) The BYPASS indicator is illuminated when the UPS is operating from BYPASS power.

    To increase this time, turn off non-essential pieces of equipment (such as idle computers and monitors) or add optional external battery cabinets. CAUTION: Turning off the UPS while in battery mode will result in loss of output power. Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger begins recharging the battery.

  • Page 23

    Output power will be restored automatically upon restoration of utility. When the UPS is standing by in this mode with the utility power absent, all panel LEDs and cooling fans will turn off.
