IMPORTANT SAFETY PRECAUTIONS

!

WARNING

Observe all cautions and warnings in this manual. Failure to do so may result in serious
injury or death.

Refer all UPS and battery service to properly trained and qualified service personnel. Do not
attempt to service this product yourself.

Opening or removing the cover may expose you to lethal voltages within this unit even when
it is apparently not operating and the input wiring is disconnected from the electrical source.

Never work alone.

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that must be followed during the installation and
maintenance of the UPS and batteries. Read this manual thoroughly before attempting to install or
operate this UPS.

UPS Safety Notes

This UPS contains no user-serviceable parts except the internal battery pack. The Off/Bypass
push button does not electrically isolate internal parts. Under no circumstances attempt to gain
internal access other than to replace the batteries due to risk of electric shock or burn. Do not
continue to use the UPS if the front panel indications are not in accordance with these operating
instructions or if the UPS performance alters in use. Refer all faults to your local dealer, Emerson
Network Power representative or Emerson Network Power Channel Support.

This UPS has an internal battery, and the output receptacles of the UPS may carry live voltage even
if the UPS is not connected to utility input power.

Before moving or rewiring this UPS, disconnect utility input power and the battery and make sure
that the UPS is completely shut down. Otherwise, the output terminal may carry live voltage,
presenting an electric shock hazard.

To ensure human safety and normal UPS operation, the UPS must be properly grounded before use.
When the UPS is connected to an IT power distribution system, a short-circuit protection device must

be installed on the neutral line.
Install and use the Liebert

• Temperature: 32°F - 104°F (0°C - 40°C), relative humidity: 0% ~ 95% non-condensing

• Out of direct sunlight

• Away from heat sources

The operating principle of the UPS is illustrated in Figure 6.

Figure 6 Operating principle diagram

Product Description

The UPS is composed of utility input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery
charger, DC-to-DC converter, battery, dynamic bypass and UPS output.

Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters

The Liebert® GXT3™ has surge protection and filters that protect the connected load from power
surges, electromagnetic interference (EMI) and radio frequency interference (RFI). These features
can minimize any surges or interference present in the utility power. The filters also prevent surges
or interference generated by the UPS from adversely affecting devices connected on the same branch
as the UPS.

Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the Liebert GXT3’s rectifier/power factor correction (PFC) circuit converts utility
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 sinewave input current achieves two objectives:

• Efficient power use by the UPS

• Reduced reflected harmonics

This results in cleaner power being available to other devices in the building not being protected by
the Liebert GXT3.

Inverter

In normal operation, the Liebert GXT3’s inverter utilizes the DC output of the PFC to produce
precise, regulated sine wave AC power. When utility power fails, the inverter receives DC power from
the DC-to-DC Converter. In either operation mode, the UPS inverter is online, continuously
generating clean, precise, regulated AC output power.

8

Battery Charger

Product Description

The battery charger utilizes energy from the utility power and precisely regulates it to continuously
float charge the batteries. The batteries are being charged whenever the Liebert
in, even when the UPS is not turned On.

DC-to-DC Converter

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 efficiency and voltage,
thus increasing reliability.

Battery

The Liebert GXT3 uses valve-regulated, nonspillable, lead acid batteries. To maintain battery design
life, operate the Liebert GXT3 in an ambient temperature of 32°F to 77°F (0°C to 25°C).

Optional external battery cabinets are available to extend battery run times.

Dynamic Bypass

The Liebert GXT3 provides an alternate path for utility power to the connected loads in the unlikely
event of a UPS malfunction. Should the Liebert GXT3 have an overload, overtemperature or UPS
failure condition, the UPS automatically transfers the connected loads to bypass.

NOTE

The bypass power path does not protect the connected loads from disturbances on the utility.

1.5 Operating Mode

®

GXT3™ is plugged

The UPS operation modes include: Utility (AC) mode, bypass mode, battery mode, battery recharge
mode and frequency converter mode.

For the descriptions of indicators and control buttons in this section, refer to 3.0 - Controls and
Indicators.

1.5.1 Utility (AC) Mode

During Utility (AC) Mode, utility power provides energy to the Liebert GXT3. The filters, PFC circuit
and the inverter process this power to provide computer-grade power to connected loads. Meanwhile,
the UPS maintains the batteries in a fully charged state.

1.5.2 Manual Bypass Mode

Manual Bypass Mode occurs when the Standby/Manual bypass button is pressed and held for about
2 seconds while the Liebert GXT3 is in Utility (AC) Mode. Bypass operation is indicated by an audible
alarm and illuminated amber bypass indicator (If other indicators are illuminated, refer to 7.0 -
Troubleshooting). During manual bypass mode, utility power bypasses the inverter and provides
energy to the connected load.

NOTICE

Turning Off the UPS in bypass mode will result in loss of output power and dropped loads.

9

1.5.3 Battery Mode

The Liebert® GXT3™ enters Battery Mode when utility power fails or is outside acceptable values.
The battery system supplies power through the DC-to-DC converter to the inverter to generate clean
AC power for the connected loads.

When the Liebert GXT3 enters Battery Mode, the UPS sounds a half-second beep at 10-second
intervals. When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to
warn that the battery is getting low (this Low Battery Warning is user-configurable).

In Battery Mode, the AC Input indicator goes Off and the Battery Level indicators illuminate. Each
battery level indicator represents a 20% capacity level. As capacity decreases, fewer indicators remain
illuminated. Refer to 7.0 - Troubleshooting.

For approximate battery run times, refer to 9.0 - Specifications.

NOTICE

Turning Off the Liebert GXT3 when it is in Battery Mode will result in loss of output power.
If the UPS is turned Off manually, it must be manually restarted after utility power returns.
If the UPS is turned Off by a communication signal or because the batteries are depleted, it

will operate as selected in the configuration program for Auto-Restart (Refer to 5.2.1 -
Configuration Program).

1.5.4 Battery Recharge Mode

Product Description

Once utility power is applied to the Liebert GXT3, the Battery Charger begins charging the batteries.

1.5.5 Frequency Converter Mode

All models of the Liebert GXT3 are capable of frequency conversion. Frequency Conversion Mode can
be selected using the configuration program. Allowable frequency operating modes include:

• Auto Sensing - 50Hz or 60Hz – Bypass Enabled

• Auto Sensing - 50Hz or 60Hz – Bypass Disabled

• Frequency Converter - 50Hz – Bypass Disabled

• Frequency Converter - 60Hz – Bypass Disabled

The default for all models of the Liebert GXT3 is “Auto Sensing - 50Hz or 60Hz – Bypass Enabled.”
