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
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.
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 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22.
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.
8 Outlet group Programmable output receptacles.
9 Outlet group General output receptacles.
10 Outlet group General output receptacles on 2,000- and 3,000-VA models only.
Table 1.2 Major Components
1.6 UPS States and Operating Modes
NOTE: See LED Indicators on page25, for description of the run-indicator and alarm-indicator LEDs
mentioned in this section.
1.6.1 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.
1 GXT5 Description 9

1.6.2 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.
1.6.3 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."
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.
NOTE: Powering-off the UPS when it is in battery mode results in loss of output power to the
connected load.
1.6.4 Frequency Converter Mode
All models of the GXT5 are capable of frequency conversion. Frequency Conversion Mode can be selected
using the configuration program. Allowable frequency operating modes include:
•Auto Sensing - 50 Hz or 60Hz – Bypass Enabled
•Auto Sensing - 50 Hz or 60Hz – 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 60Hz – Bypass
Enabled.”
1.6.5 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.
