1.6. Major Internal Components and Operating Principle
Figure 1-9 on the next page, shows the UPS operating principle. Table 1-2 on the next page, describes the
function of the major components in the UPS.
NOTE: Figure 1-9 on the next page, is one example of basic operation.
GXT5 Description12
Figure 1-9 Basic Operating Principle Diagram
Table 1-2 Major Components
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.
2Rectier/Power Factor
Correction (PFC) Circuit
In normal operation, 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
eicient use of utility power and reduces reected harmonic distortion making cleaner power available to devices
that are not protected by the UPS.
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 eiciency and voltage, thus increasing reliability.
3 Battery Charger Regulates input AC power to continuously float-charge the batteries. Batteries are charged when the UPS is
plugged in, even when not powered-on.
4 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).
5 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.
6Dynamic 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 34.
7 EMI/RFI Filters Filter electromagnetic interference (EMI) and radio frequency interference (RFI). Minimize interference present in
the utility power and protect devices connected on the same branch as the UPS.
8Maintenance
Bypass
In the unlikely event of UPS failure, allows replacing the UPS while keeping the connected equipment powered
with utility power.
NOTE: The bypass power path does not protect connected equipment from disturbances in the utility supply.
15-kVA and 20-kVA units do not have internal maintenance bypass.
9 Outlet group General output receptacles.
Vertiv | Liebert® GXT5™ | Installer/User Guide 13
1.7. UPS States and Operating Modes
NOTE: See LED Indicators on page 39, 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 rectier 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.
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.”
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 “Flow” screen displays “On Battery.”
NOTE: The batteries are fully-charged before shipment. However, transportation and storage inevitably
cause some loss of capacity. To ensure adequate back-up time, it is recommended to 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.
NOTE: Powering-o the UPS when it is in battery mode results in loss of output power to the connected
load.
GXT5 Description14
1.7.4. Frequency Converter Mode
All models of the GXT5 are capable of frequency conversion. Frequency Conversion Mode can be selected
using the conguration program. Allowable frequency operating modes include:
• Auto Sensing - 50 Hz or 60 Hz – Bypass Enabled
• Auto Sensing - 50 Hz or 60 Hz – Bypass Disabled
• Frequency Converter - 50 Hz – Bypass Disabled
• Frequency Converter - 60Hz – Bypass Disabled
NOTE: The default for all models of the Liebert® GXT5 is “Auto Sensing - 50 Hz or 60 Hz – Bypass Enabled.”
1.7.5. ECO Mode
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 and
therefore the load will shut down.
Vertiv | Liebert® GXT5™ | Installer/User Guide 15
Chapter 2: Installation
Do not start the UPS until after the installation is nished.
WARNING! Risk of electric shock
Can cause equipment damage, injury and death. Before beginning installation, verify that all external overcurrent
protection devices are open (O), and that they are locked-out and tagged appropriately to prevent activation

2.9. Hardwired Input/Output Connections
WARNING! Risk of electric shock
Can cause equipment damage, injury and death. Before beginning installation, verify that all external over-
current protection devices are open (O), and that they are locked-out and tagged appropriately to prevent
activation during the installation, verify with a voltmeter that power is O and wear appropriate, OSHA-
approved personal protective equipment (PPE) per NFPA 70E. Failure to comply can cause serious injury or
death. Before proceeding with installation, read all instructions. Follow all local codes.
Observe the following guidelines and specications when making the hard-wire input and output connections:
• We recommend installing a UL489-approved breaker upstream of unit.
• Provide circuit-breaker protection according to local codes. The mains disconnect should be within sight of
the UPS or have an appropriate lock-out.
• Maintain service space around the UPS or use exible conduit.
• Provide output-distributions panels, circuit-breaker protection, or emergency disconnects according to local
codes.
Vertiv | Liebert® GXT5™ | Installer/User Guide 25
• Do not install input and output wiring in the same conduit.
• On models with a cord-connected input plug that is used as the power-disconnect device, the UPS must
be installed near a wall socket or outlet that is easily accessible per the National Electric Code/NFPA 70
requirements. Models/POD options subject to this requirement are: GXT5-5000MVRT4UXLN and
GXT5-6000MVRT4UXLN with POD PD5-001, PD5-002, PD5-003, PD5-004, PD5-005, or PD5-006
2.9.1. Branch Circuit Breaker
The installer must provide an upstream branch circuit breaker, see Table 2-1 below, for the ratings. The input
circuit breaker on the distribution box and the output circuit breaker on the rear of the power distribution box
disconnect all power between the main cabinet and the distribution box. Figure 2-7 on the next page, shows a

2.10.3. Connecting a Remote Emergency Power-o (REPO) Switch
The UPS includes an EPO connection in the dry-contact port. See the appropriate gure for your model in Rear
Panels on page 5, for the location of the port.
UPS ships with a REPO jumper installed, allowing the UPS to operate as a normally-closed switch system (fail-
safe). Opening the circuit disables the UPS. To connect a REPO switch that opens the circuit to shut down the
rectier and inverter and power-o the UPS, use a cable from the remote switch to plug into the REPO-port on
the UPS.
In normal conditions, the REPO switch cannot cut o the UPS input power. When the REPO switch trips, the
UPS generates an alarm and immediately cuts-o output power. When the emergency condition is resolved, the
UPS will not return to normal operation until you reset the REPO switch and manually power- on the UPS.
To make the cable for the REPO connection:
Figure 2-10 below, shows the cable required to make the connection. We recommend using 18 AWG to 22 AWG
(0.82 mm2 to 0.33 mm2) copper-core cable.
1. Remove the insulation from the end of two cables.
2. Insert the stripped end into the plug terminals 1 and 2 respectively, then press down the terminals. Make
sure that the cables are secure in the plug to prevent failure because of loose contact.
To connect a UPS to the REPO switch.
CAUTION
To maintain safety (SELV) barriers and electromagnetic compatibility, signal cables should be shielded and run
separately from power cables.
1. Connect one end of the cable to the remote switch, see Figure 2-10 below.
2. Remove the factory-installed jumper from pins 7 and 8 of the dry-contact port on the UPS
3. Connect the plug to pins 7 and 8.

3.6. Shutting-down the UPS Completely
WARNING! Risk of electric shock
Can cause injury or death. Disconnect all local and remote electric power supplies before working with the UPS.
Ensure that the unit is shut down and power has been disconnected before beginning any maintenance.
Transfer to Bypass mode, see “Transferring from Bypass to Normal Mode” on page 34. Then, if power to the
load is not needed, open the main-input circuit breaker.
For systems with direct power distribution, isolate the UPS from AC power by disconnecting the external input
MCB. If the main and bypass are independently powered, close the two input MCBs.
3.7. Remote Emergency Power-o (REPO)
REPO turns o the UPS in emergency conditions such as re or ood. When an emergency occurs, the REPO
switch turns o the rectier and inverter and stops powering the load immediately. The battery stops charging
and discharging.
To manually power-o in an emergency, disconnect the terminal connecting the REPO port on the rear of the
UPS.
If mains/utility power is present, the UPS control circuit remains active even though output power is disabled.
To remove all mains/utility power, disconnect the external main-input circuit breaker.

Operation and Display Panel58
4.2.7. About Screen
The About screen oers tabs that list information about the product.
• Product tab—shows UPS identication information, rmware versions, and information about the
communication card (when the card is installed).
• Eiciency tab—shows curve of the eiciency of your UPS model vs the load. The eiciency at the current
load is shown to the right of the graph.
• Battery age tab—shows the curve of the state-of-health (SOH) percentage of the installed battery over time.
The SOH is measurement of the installed battery’s condition and ability to deliver the specied performance
compared to a fresh battery. During the lifetime of a battery, its health will deteriorate gradually due to
irreversible physical and chemical changes which take place with usage and with age until eventually the
battery is no longer usable. The UPS calculates one value per week and plots it on the graph. The values are
based on battery temperature, age, and the total amount of energy discharged from the battery that week.
With use over time, this percentage will decrease until the “Battery Aged” alarm is generated at 25%. It is
recommended to replace the battery at or before this time.
To view the product, eiciency, and battery-age information:
1. At the main menu, select the About icon, and press Enter.
2. Use the arrow buttons to move the cursor left/right and select a tab, then press Enter to display the
