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.

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.

3 Batteries

Suppression (TVSS)and EMI/RFI Filters

DC-to-DC Converter

Rectifier/Power Factor Correction (PFC) Circuit

Provide surge protection. Filter electromagnetic interference (EMI) andradio frequency interference (RFI). Minimize surges or interference present in the utility power and protect devices connected on the same branch as the UPS.

Continuouslyfloat-charges the batteries from precisely-regulated utility power whenever the UPS is plugged in.

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).

Raises the DC voltage from the battery to the optimum operating voltage for the inverter. This allows the inverter to operate continuouslyat its optimum efficiency and voltage, thus increasingreliability.

In normal operation, converts utility ACpower to regulated DC power for use bythe inverter while ensuring that the wave shape of the input current used bythe UPS isnear 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 bythe UPS.

ITEM COMPONENT OPERATION/FUNCTION

In normal operation, inverts the DC output of the PFC c ircuit into precise, regulated sine-wave AC power.

6 Inverter

7 Internal Bypass

8 Outlet group Output receptacles.

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.

In the unlikelyevent 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.

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 frontpanel 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 bypassmode 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 atleast 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.

1.7.4 ECO Mode

NOTE: ECO mode is only available on a single-UPS system.

The energy-saving ECO mode reduces power consumption by powering the load via bypass if the bypass voltage is normal or by powering the load via the inverter when the bypass voltage is abnormal. You can use ECOmode to power equipment that is not sensitive to power-grid quality to via bypass and reduce power consumption.

NOTE: During Eco mode, if a bypass-failure or abnormal-bypass-voltage notification appears when the output is not overloaded, the UPS will transfer to Normal Mode. However, if a notification showing bypass failure or abnormal bypass voltage appears when the output is overloaded, the UPS will shut down the bypass.

1 GXT5 Description

1.7.5 Maintenance Bypass Mode

NOTE: 5-kVA to 10-kVA models include an MCB to switch the load to bypass. On 16-kVA to 20-kVA models, a dry contact may be used to trigger maintenance bypass.

Used when the UPS requires maintenance or repair, Maintenance-bypass mode powers the connected equipment with utility power while electrically isolating the internal UPS components.

NOTICE

Risk of power interruption. Can damage the connected equipment.

If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode, the UPS may shut down without notice and shut-off output power to the load.

NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit http://www.VertivCo.com/en-us/support/ or contact your local Vertiv representative.
