Battery

The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger, DC-to-DC converter, battery, dynamic bypass and UPS output.

Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters The Liebert GXT4 has surge protection and filters that protect the connected load from power surges and sags, electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize any surges or interference present in the mains power. The filters also prevent surges or interference generated by the UPS from adversely affecting other devices connected on the same branch as the UPS.

Rectifier/Power Factor Correction (PFC) Circuit In normal operation, the Liebert GXT4’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 GXT4’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 GXT4 is plugged in, even when the UPS is not turned On.

Liebert® GXT4™

Product Description

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 GXT4 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the Liebert GXT4 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 GXT4 provides an alternate path for mains power to the connected loads in the unlikely event of a UPS malfunction. Should the Liebert GXT4 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, Active ECO Mode and Frequency Converter Mode. Refer to 3.0 - Operation and Display Panel for details about the operating mode indicators and control buttons.

1.5.1

Mains Mode During Mains Mode, the mains provides input power to the Liebert GXT4. The filters, PFC circuit and inverter process this power to provide high-quality sine wave power to connected loads. The UPS maintains the batteries in a fully charged state.

1.5.2

Manual Bypass Mode Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD display menu to select 3 Control > 1 Turn On & Off > Turn UPS Bypass. 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 Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load.

Liebert® GXT4™

Product Description

1.5.3

Battery Mode The Liebert GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. 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 GXT4 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 battery indicator will illuminate and the LCD will show the prompt Silence Alarm and choices of Yes and No. The default is No. Press either the Up or Down arrow button to select Yes, then press the Enter button to silence the alarm. Once the alarm prompt has been acknowledged, the UPS will display the estimated battery run time and battery capacity. Refer to 7.0 - Troubleshooting. For approximate battery run times, refer to Table 17.

NOTICE Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the Liebert GXT4 when it is in Battery Mode will result in loss of output power to the connected load. 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 set in the configuration program for Auto-Restart (Refer to 5.2.1 Configuration Program).

1.5.4

Battery Recharge Mode Once mains power is applied to the Liebert GXT4, the Battery Charger begins charging the batteries.

1.5.5

Frequency Converter Mode All models of the Liebert GXT4 are capable of frequency conversion. Frequency Conversion Mode can be selected using the configuration program. Allowable frequency operating modes include: • Auto Sensing - 50Hz or 60Hz – Bypass Enabled • Auto Sensing - 50Hz or 60Hz – Bypass Disabled • Frequency Converter - 50Hz – Bypass Disabled • Frequency Converter - 60Hz – Bypass Disabled NOTE The default for all models of the Liebert GXT4 is “Auto Sensing - 50Hz or 60Hz – Bypass Enabled.”

! CAUTION Risk of electric shock. Can cause injury or death. Never touch the AC input receptacle while the UPS is operating. Voltage may still be present even when the AC input indicator is Off.

1.5.6

Active ECO Mode All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is powered through the bypass path to increase efficiency, reducing the electrical costs. Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain synchronized to bypass. This synchronization allows the transfer of the connected equipment to UPS inverter power almost seamlessly if bypass power falls outside the user-set limits. Once bypass power returns within the acceptable parameters, the UPS will return to Active ECO Mode operation. The default setting is Active ECO Mode Off.
