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

Product Description

These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize any surges or interference present in the mains line and keep the sensitive equipment protected.

1.6.2 Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the rectifier/power factor correction (PFC) circuit converts mains AC power to regulated DC power for use by the inverter while ensuring that the waveshape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives:

• The mains power is used as efficiently as possible by the UPS.

• The amount of distortion reflected on the mains is reduced.

This results in cleaner power being available to other devices in the building not being protected by the Liebert GXT4.

1.6.3 Inverter

In normal operation, the inverter utilizes the DC output of the power factor correction circuit and inverts it into precise, regulated sinewave AC power. Upon a mains power failure, the inverter receives its required energy from the battery through the DC-to-DC converter. In both modes of operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output power.

1.6.4 Battery Charger

The battery charger utilizes energy from the mains power and precisely regulates it to continuously float charge the batteries. The batteries are being charged whenever the Liebert GXT4 is connected to mains power.

1.6.5 DC-to-DC Converter

The DC-to-DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability.

Liebert® GXT4

™

1.6.6 Battery

The Liebert GXT4 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F). Optional external battery cabinets are available to extend battery run times. For run times, see Table 16.

1.6.7 Internal Bypass

The Liebert GXT4 provides an alternate path for mains power to the connected load in the unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature or any other UPS failure condition, the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated to indicate the diagnosed problem). To manually transfer the connected load from the inverter to bypass, press the Standby/Manual Bypass button once and hold it for about 2 seconds

1.6.8 Maintenance Bypass

The Liebert GXT4 provides a manual maintenance bypass that is located in a removable section of the rear of the UPS. This allows replacement of the UPS, in the unlikely event of a UPS malfunction, while keeping the connected equipment powered with mains power.

NOTE

The bypass power path does NOT protect the connected equipment from disturbances in the mains supply.

Product Description

1.7 Operating Mode

The UPS operation modes include the following: Mains (AC) Mode, Bypass Mode, Battery Mode, Battery Recharge Mode, Active ECO Mode and Frequency Converter Mode.

Refer to 3.0 - Operation and Display Panel for details about the operating mode indicators and control buttons.

1.7.1 Mains Mode

During Mains Mode, the mains provides input power to the Liebert GXT4. The filters, PFC circuit and inverter process this power to provide high-quality sine wave power to connected loads. The UPS maintains the batteries in a fully charged state.

1.7.2 Manual Bypass Mode

Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD display menu to select 3 Control > 1 Turn On & Off > Turn UPS Bypass. Bypass operation is indicated by an audible alarm and illuminated amber bypass indicator. (If other indicators are illuminated, refer to 7.0 - Troubleshooting). During Bypass Mode, mains power bypasses the inverter and provides energy to the connected load.

NOTICE

Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load.

9Liebert

GXT4

™

1.7.3 Battery Mode

The Liebert GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. 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 GXT4 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 battery indicator will illuminate and the LCD will show the prompt utility power not available.

Press either the Up or Down button once, then press the Enter button to clear the prompt and silence the audible alarm. Once the alarm has been acknowledged, the screen showing the estimated battery run time and battery capacity will be visible. Refer to 7.0 - Troubleshooting.

For approximate battery run times, refer to Table 16.

NOTICE

Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the Liebert GXT4 when it is in Battery Mode will result in loss of output power to

the connected load. If the UPS is turned Off manually, it must be manually restarted after mains power returns. If the UPS is turned Off by a communication signal or because the batteries are depleted, it

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

Product Description

1.7.4 Battery Recharge Mode

Once mains power is applied to the Liebert GXT4, the Battery Charger begins charging the batteries.

1.7.5 Frequency Converter Mode

All models of the Liebert GXT4 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

NOTE

The default for all models of the Liebert GXT4 is “Auto Sensing - 50Hz or 60Hz – Bypass Enabled.”

CAUTION

Risk of electric shock. Can cause injury or death. Never touch the AC input receptacle while the UPS is operating. Voltage may still be present

even when the AC input indicator is Off.

1.7.6 Active ECO Mode

All Liebert GXT4 models can operate in Active ECO Mode. In this mode, the connected equipment is powered through the bypass path to increase efficiency, reducing the electrical costs.

Active ECO mode keeps the rectifier and inverter operating, allowing the inverter to remain synchronized to bypass. This synchronization allows the transfer of the connected equipment to UPS inverter power almost seamlessly if bypass power falls outside the user-set limits. Once bypass power returns within the acceptable parameters, the UPS will return to Active ECO Mode operation.

The default setting is Active ECO Mode Off.

Maintenance

NOTE

The internal battery pack is hot-swappable. However, caution should be exercised because the load is unprotected from disturbances and power failures during this procedure. Do not replace the battery while the UPS is operating in Battery Mode. This will result in a loss of output power and will drop the connected load.

6.2 Battery Charging

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The Liebert GXT4 charges the batteries continuously when it is connected to the mains input power.

If the Liebert GXT4 will be stored for a long time, Emerson recommends connecting the UPS to input power for at least 24 hours every four to six months to ensure full recharge of the batteries.

6.3 Precautions

Although the Liebert GXT4 has been designed and manufactured to ensure personal safety, improper

use can result in electrical shock or fire. To ensure safety, observe the following precautions:

• Turn Off and unplug the Liebert GXT4 before cleaning it.

• Wear rubber gloves and boots.

• Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.

• Never block or insert any objects into the ventilation holes or other openings of the UPS.

• Do not place the Liebert GXT4 power cord where it might be damaged.

6.4 Checking UPS Status

Emerson® recommends checking the UPS operation status every six months.

• Check whether the UPS is faulty: Is the Fault Indicator On? Is the UPS sounding an alarm?

• Check whether the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal Mode. If it is operating in Bypass Mode, stop and contact your local Emerson representative, or Emerson Channel Support.

• Check whether the battery is discharging. When the mains input is normal, the battery should not discharge. If the UPS is operating in Battery Mode, stop and contact your local Emerson representative or Emerson Channel Support.

6.5 Checking UPS Functions

NOTE

UPS function check procedures may interrupt power supply to the connected load.

Emerson recommends checking the UPS functions once every six months.

Back up the load data before conducting the UPS functions check. Procedures are as follows:

1. Press the Standby/Manual Bypass button to check whether the buzzer and indicators are normal.

2. Press the On/Alarm Silence/Manual Battery Test button to check again whether the indicators are On and the UPS is operating normally.

3. Press the On/Alarm Silence/Manual Battery Test button for three seconds after Inverter Mode. The UPS should initiate a battery self-test. Check to determine whether the battery is operating normally. If not, stop and contact your local Emerson representative or Emerson Channel Support

Using the configuration program, the user may specify the number of GXT4-240VBATT external battery cabinets attached to the UPS. The factory default is programmed for internal batteries only.

Table 16 shows the estimated run times at different loads.

47 Liebert® GXT4

™

8.1 Auto-Learning Battery Run Times

As batteries age, the estimated run times may become less accurate. The Liebert GXT4 is programmed to “learn” from a full battery discharge and modify the estimated runtime for the measured battery capacity. This can improve accuracy and compensate for aging batteries or batteries that operate at different ambient temperatures.

The UPS will update the anticipated run time calculation only under certain conditions.

• The UPS must have a steady load that is greater than 20%.

• The UPS must be at 100% charge at the start of a battery discharge.

• The battery discharge must continue uninterrupted until the batteries reach their end-ofdischarge voltage.

If all conditions are not met, the run time calculation will not be modified.

If the configuration program is used to change the number of battery cabinets, then the values in the battery above table will be restored. This will override any value that is Auto-Learned.
