NTRODUCTION
Congratulations on your choice of the Liebert ® GXT3 ™ uninterruptible power system (UPS). The
Liebert GXT3 comes in nominal power ratings of 5000VA, 6000VA, 8000VA and 10,000VA. It is designed to provide conditioned power to microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and distribution it is subject to voltage sags, spikes and complete power failure that may interrupt computer operations, cause data loss and even damage equipment. The Liebert GXT3 protects equipment from these disturbances.
The Liebert GXT3 is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its output voltage, whether utility power is present or not. It supplies connected equipment with clean, sinewave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the Liebert GXT3 features a light-emitting diode (LED) display to indicate both load percentage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm
Silence/Manual Battery Test button, a Standby/Manual Bypass button and a configuration program.
The Liebert GXT3 has a Liebert IntelliSlot ® port for communication between the UPS and a network server or other computer systems. This port provides detailed operating information including voltages, currents and alarm status to the host system when used in conjunction with Liebert
MultiLink ® . Liebert MultiLink can also remotely control UPS operation.

2.1
Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize any surges or interference present in the utility line and keep the sensitive equipment protected.
2.2
Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility AC power to regulated DC power for use by the inverter while ensuring that the waveshape 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.
• The amount of distortion reflected on the utility is reduced.
This results in cleaner power being available to other devices in the building not being protected by the Liebert ® GXT3 ™ .
2.3
Inverter
In normal operation, the inverter utilizes the DC output of the power factor correction circuit and inverts it into precise, regulated sinewave AC power. Upon a utility power failure, the inverter receives its required energy from the battery through the DC-to-DC converter. In both modes of operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output power.
2.4
Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to continuously float charge the batteries. The batteries are being charged whenever the Liebert GXT3 is connected to utility power.
2.5
DC-to-DC Converter
The DC-to-DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.
5
System Description
2.6
Battery
The Liebert ® GXT3 ™ utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional
external battery cabinets are available to extend battery run times. For run times, see Table 14.
2.7
Dynamic Bypass
The Liebert GXT3 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, overtemperature or any other UPS failure condition, the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated to indicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass, press the Standby/Manual Bypass button once and hold it for about 2 seconds.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances in the utility supply.

Fault indicator and diagnostic
A and B indicators are illuminated
AC input indicator is flashing.
UPS failure (includes dual-fan failure, single-fan failure under certain conditions and battery charger failure) and continuous alarm
UPS detected a line-to-neutral reversal or a loss of proper grounding for UPS; continuous horn and UPS cannot start up in standby status. This is active only when power is first applied to the input. Once the
UPS is running, the AC input indicator will flash, unless the input wiring is correctly changed.
Ensure fan is not blocked up. If the fault is not removed, contact your local dealer, Emerson representative or
Emerson Channel Support.
Contact a qualified electrician to verify site wiring.
Battery indicator is flashing.
Bypass indicator is flashing.
Battery source is not available; continuous horn.
Because the voltage or frequency is outside acceptable limits, the bypass is disabled.
Check battery connections, completely power down and restart UPS.
NOTE: If the battery circuit opens while the UPS is running, it will be detected when the next battery test is performed.
The AC input powers the PFC input and serves as the bypass source. If the AC is present but the voltage or frequency exceeds the acceptable range for safe operation with a load, the bypass will be disabled and this indicator will flash, indicating that the bypass is unavailable.
When reporting a UPS issue to Emerson, include the UPS model and serial number. These are on the top panel of the Liebert ® GXT3 ™ .

Specifications
Using the configuration program, the user may specify the number of external battery cabinets attached to the UPS. The factory default is programmed for internal batteries only.
Table 14 shows the estimated run times at different loads.
12.1 Auto-Learning Battery Run Times
As batteries age, the estimated runtimes may become less accurate. The Liebert ® GXT3 is programmed to “learn” from a full battery discharge and modify the estimated run time for the measured battery capacity. This can improve accuracy and compensate for aging batteries or batteries that operate at different ambient temperatures.
The UPS will update the anticipated run time calculation only under certain conditions.
• The UPS must have a steady load that is greater than 20%.
• The UPS must be at 100% charge at the start of a battery discharge.
• The battery discharge must continue uninterrupted until the batteries reach their end-of-discharge voltage.
If all conditions are not met, the run time calculation will not be modified.
If the configuration program is used to change the number of battery cabinets, then the values in
Table 14 will be restored. This will override any value that is Auto-Learned.
