1 GXT5 DESCRIPTION
The Liebert® GXT5 is a compact, online uninterruptible power system (UPS) that continuously conditions
and regulates its output voltage. The Liebert® GXT5 supplies microcomputers and other sensitive
equipment with clean sine-wave input power.
Upon generation, AC power is clean and stable. However, during transmission and distribution it is subject
to voltage sags, spikes, and complete failure that may interrupt computer operations, cause data loss, and
damage equipment.
The Liebert® GXT5 protects equipment from these disturbances. The Liebert® GXT5 continuously
charges its batteries from the mains, enabling it to supply power to connected loads, even when the mains
fail.
1.1 UPS Features and Available Models
The GXT5 includes the following features. Table 1.1 on the next page, lists the available models and
power ratings.
•Enhanced load capacity with an output power factor of 1.
•Optional tower or rack installation to meet varying installation requirements.
•Parallel-connection capability for 10-kVA, 16-kVA, and 20-kVA models achieves up to 2 + 1
parallel redundant power.
•Adapts to areas with unstable power-mains supply via high-frequency double-conversion
topology structure, with high input-power factor, wide input-voltage range, and output
immune to grid interference.
•Full digital-control platform and hardware-design platform adapts to unstable mains supply
and load impact
•Programmable terminals with cascade protection on 5-kVA to 10-kVA models protect key
devices when load is heavy.
•Innovative design layout and process greatly increase product reliability.
•Operation and display panel with model-specific color LCD offers simple configuration and
control of the UPS.
•ECO power-supply mode and smart-sleep mode help you save the maximum amount of energy.

The various GXT5 models have the same general appearance, with the main difference being the
receptacle types on the rear panel. Figure 1.1 below, shows the 5-kVAto10-kVA model in a tower and a
rack configuration. When mounted in a rack, the 5- to 10-kVA units are turned 90 degrees. The
orientation of the 16-kVA to 20-kVA models is the same in a rack or tower configuration.

1.6 Major Internal Components and Operating Principle
Figure 1.12 below, shows the UPSoperating principle. Table 1.2 on the next page, describes the function
of the major components in the UPS.
NOTE: Figure 1.12 below, is one example of basic operation. The actual I/O connections for the
various models may be divided into different types. See Hardwired Input/Output Connections on
page25.
Figure 1.12 Basic Operating Principle Diagram
ITEM COMPONENT OPERATION/FUNCTION
1
Transient
Voltage Surge
Suppression
(TVSS) and
EMI/RFI Filters
Provide surge protection. Filter electromagnetic interference (EMI) and radio frequency interference
(RFI). Minimize surges or interference present in the utility power and protect devices connected on the
same branch as the UPS.
2 Battery Charger Continuously float-charges the batteries from precisely-regulated utility power whenever the UPS is
plugged in.
3 Batteries
Valve-regulated, non-spillable, lead-acid batteries.
NOTE: To maintain battery design life, operate the UPS in an ambient temperature of 59°F to 77°F
(15°C to 25°C).
4DC-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, thus increasing reliability.
5
Rectifier/Power
Factor
Correction
(PFC) Circuit
In normaloperation, converts utility 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 sine-wave
input current ensures efficient use of utility power and reduces reflected harmonic distortion making
cleaner power available to devices that are not protected by the UPS.
Table 1.2 Major Components
1 GXT5 Description 13

ITEM COMPONENT OPERATION/FUNCTION
6 Inverter
In normal operation, inverts the DC output of the PFC circuit into precise, regulated sine-wave AC power.
When utility power fails, the inverter receives DC power from the DC-to-DC converter. In either
operating mode, the UPS inverter remains on-line, generating clean, precise, regulated AC-output
power.
7 Internal Bypass
In the unlikely event of UPS failure such as overload or over-temperature, automatically transfers the
connected load to bypass.
To manually transfer the connected load from inverter to bypass, see Transferring from Normal to
Bypass Mode on page40.
8 Outlet group Output receptacles.
Table 1.2 Major Components (continued)
1.6.1 Maintenance Bypass
On 5-kVA to 10-kVA models, the UPS includes manual maintenance bypass in a removable section of the
rear of the UPS. Maintenance bypass keeps connected equipment powered with utility power and allows
replacement of the UPS in the event of a UPS malfunction.
NOTE: The bypass power path does not protect the connected equipment from disturbances in the
utility power supply.
1.7 UPS States and Operating Modes
NOTE: See LED Indicators on page42, for description of the run-indicator and alarm-indicator LEDs
mentioned in this section.
1.7.1 Normal Mode
When utility power is normal, Normal mode employs the rectifier and inverter to provide voltage- and
frequency-stabilized power to the load. The charger charges the battery in normal mode. On the front-
panel display, the run-indicator (green)is On, the alarm indicator is OFF, and the buzzer is silent. Figure
1.13 on the facing page, shows a diagram of normal mode.

1.7.2 Bypass Mode
Bypass mode supplies power to the load from the bypass source (utility power) if an overload or fault
occurs during normal operation. On the front-panel display, the run indicator (green) is On, the alarm
indicator (yellow)is On, and the buzzer beeps once each seconds. The LCD "Current" screen displays "On
Bypass." Figure 1.14 on the next page, shows a diagram of bypass mode.
NOTE: If utility power fails or if the utility voltage goes outside of the permissible range during bypass-
mode operation, the UPS shuts down and no output is supplied to the load.

1.7.3 Battery Mode
Battery mode supplies battery power to the load if utility power fails or if the utility voltage goes outside of
the permissible range. On the front-panel display, the run indicator (green) is On, the alarm indicator
(yellow)is On, and the buzzer beeps once each second. The LCD "Current" screen displays "On Battery."
Figure 1.15 on the facing page, shows a diagram of battery mode.
NOTE: The batteries are fully-charged before shipment. However, transportation and storage
inevitably cause some loss of capacity. To ensure adequate back-up time, charge the batteries for at-
least 8 hours before first start-up.
NOTE: If utility power fails and the batteries are charged, you may cold-start the UPS in battery mode
and use battery power to extend system availability for a time.
