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.
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.
Regulates input AC power to continuously float-charge the batteries. Batteries are charged when the UPS is
plugged in, even when not powered-on.
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).
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.
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.
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.
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.

GXT5 Description12
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 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 “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.
Vertiv | Liebert® GXT5™ | Installer/User Guide 13
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.
GXT5 Description14
Chapter 2: Installation
Do not start the UPS until after the installation is nished.
WARNIN G! Ris k 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
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
2.1. Unpacking and Inspection
Unpack the UPS and conduct the following checks:
• Inspect the UPS for shipping damage. If any shipping damage is found, report it to the carrier and your local
Vertiv representative immediately.

WARNING! Risk of electric shock
Can cause injury or death. The UPS must be shut down or the load must be transferred to an external
maintenance bypass before a power distribution box may be added, changed or removed. If the UPS
will be shut down, the connected load must be shut down. If the UPS will be transferred to maintenance
bypass, it must be transferred to an external maintenance bypass. Verify that the GXT5 is shut down
and that all local and remote electric input power has been disconnected before beginning any work
on or in the UPS.

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 overcurrent 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, OSHAapproved 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.
