Product Description  
Rectifier/Power Factor Correction (PFC) Circuit  
In normal operation, the Liebert GXT3’s rectifier/power factor correction (PFC) circuit converts mains  
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 sine wave input current achieves two  
objectives:  
• Efficient power use by the UPS  
• Reduced reflected harmonics  
This results in cleaner power being available to other devices in the building that are not protected by  
the UPS.  
Inverter  
In normal operation, the Liebert GXT3’s inverter utilizes the DC output of the PFC circuit to produce  
precise, regulated sine wave AC power. When mains power fails, the inverter receives DC power from  
the battery through the DC-to DC converter. In either operation mode, the UPS inverter is online,  
continuously generating clean, precise, regulated AC output power.  
Battery Charger  
The battery charger utilizes energy from the mains power and precisely regulates it to continuously  
float charge the batteries. The batteries are being charged whenever the Liebert GXT3 is plugged in,  
even when the UPS is not turned On.  
DC-to-DC Converter  
The DC-to-DC converter raises the DC voltage from the battery to the optimum operating voltage for  
the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage,  
increasing reliability.  
Battery  
The Liebert GXT3 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery  
design life, operate the Liebert GXT3 in an ambient temperature of 0°C to 25°C (32°F to 77°F).  
Optional external battery cabinets are available to extend battery run times.  
Dynamic Bypass  
The Liebert GXT3 provides an alternate path for mains power to the connected loads in the unlikely  
event of a UPS malfunction. Should the Liebert GXT3 have an overload, overtemperature, or UPS  
failure condition, the UPS automatically transfers the connected loads to bypass.  
NOTE  
The bypass power path does not protect the connected loads from disturbances on the mains.  
1.5  
Operating Mode  
The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode,  
Battery Recharge Mode and Frequency Converter Mode.  
For the descriptions of operation mode indicators and control buttons, refer to 3.0 - Operation and  
1.5.1 Mains (AC) Mode  
During Mains (AC) Mode, the mains provides energy to the Liebert GXT3. The filters, PFC circuit and  
inverter process this power to provide high-level power to connected loads. Meanwhile, the UPS  
maintains the batteries in a fully charged state.

Product Description  
1.5.2 Manual Bypass Mode  
Manual Bypass Mode occurs when the Standby/Manual Bypass button is pressed and held for about  
2 seconds while the Liebert GXT3 is in Mains (AC) Mode. Bypass operation is indicated by an audible  
alarm and illuminated amber bypass indicator. (If other indicators are illuminated, refer to 7.0 -  
Troubleshooting). During Bypass Mode, mains power bypasses the inverter and provides energy to  
the connected load.  
NOTICE  
Turning Off the UPS in Bypass Mode will result in loss of output power.  
1.5.3 Battery Mode  
The Liebert GXT3 enters Battery Mode when mains power fails or is outside acceptable values. The  
battery system supplies power through the DC-to-DC converter to the inverter to generate clean AC  
power for the connected loads.  
When the Liebert GXT3 enters Battery Mode, the UPS sounds a half-second beep at 10-second  
intervals. When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to  
warn that the battery is getting low (this Low Battery Warning is user-configurable).  
In Battery Mode, the AC Input indicator is Off and the Battery Level indicators illuminate to warn  
that a mains problem has occurred. Each battery level indicator represents a 20% capacity level. As  
capacity decreases, fewer indicators remain illuminated. Refer to 7.0 - Troubleshooting.  
For approximate battery run times, refer to Table 15.  
NOTICE  
Turning Off the Liebert GXT3 when it is in Battery Mode will result in loss of output power.  
If the UPS is turned Off manually, it must be manually restarted after mains power returns.  
If the UPS is turned Off by a communication signal or because the batteries are depleted, it  
will operate as selected in the configuration program for Auto-Restart (Refer to 5.2.1 -  
1.5.4 Battery Recharge Mode  
Once mains power is applied to the Liebert GXT3, the Battery Charger begins charging the batteries.  
1.5.5 Frequency Converter Mode  
All models of the Liebert GXT3 are capable of frequency conversion. Frequency Conversion Mode can  
be selected using the configuration program. Allowable frequency operating modes include:  
• Auto Sensing - 50Hz or 60 Hz – Bypass Enabled  
• Auto Sensing - 50Hz or 60 Hz – Bypass Disabled  
• Frequency Converter - 50Hz – Bypass Disabled  
• Frequency Converter - 60Hz – Bypass Disabled  
NOTE  
The default for all models of the Liebert GXT3 is “Auto Sensing - 50Hz or 60 Hz – Bypass  
Enabled.”  
CAUTION

UPS is running, the AC input  
indicator will flash, unless the  
input wiring is correctly  
changed.  
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.  
Battery source is not available;  
continuous horn.  
Battery indicator is flashing.  
Bypass indicator is flashing.  
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.  
Because the voltage or  
frequency is outside  
acceptable limits, the bypass is  
disabled.  
When reporting a UPS issue to Emerson, include the UPS model and serial number. These are on the  
top panel of the Liebert GXT3.
