2.7 Major Components

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

Figure 2.7 Operating principle diagram

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

The UPS 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 mains power. The filters also prevent surges or interference generated by the UPS from adversely affecting devices connected on the same branch as the UPS.

2.7.2 Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the rectifier/PFC circuit converts mains 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 achieves two objectives:

• Efficient power use by the UPS

• Reduced reflected harmonics

This results in cleaner power available to other devices in the building that are not protected by the

GXT4.

2.7.3 Inverter

In normal operation, the inverter utilizes the DC output of the PFC circuit to produce precise, regulated sine-wave AC power. When mains 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.

2.7.4 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 GXT4 is plugged in, even when the

UPS is not turned On.


16

2.7.5 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.

2.7.6 Battery

The GXT4 uses valve-regulated, non-spillable, lead acid batteries. To maintain battery design life, Operate the GXT4 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.

2.7.7 Internal Bypass

The 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, over-temperature 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

2.7.8 Maintenance Bypass

The GXT4 provides a manual maintenance bypass in a removable section of the rear of the UPS. This allows replacement of the UPS in the event of a UPS malfunction while keeping the connected equipment powered with utility power.

NOTE: The bypass power path does not protect the connected equipment from disturbances in the mains supply.

2.8 Operating Modes

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

Operation and Display Panel on page 31 for details about the operating mode indicators and

control buttons.

2.8.1 Mains Mode

During Mains Mode, the mains provides input power to the 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.


17

2.8.2 Manual Bypass Mode

Manual Bypass Mode occurs when the unit is manually placed in internal bypass by navigating the LCD menu to select 3 Control > 1 Turn O n & O ff > Turn UPS Bypass. Bypass operation is indicated by an audible alarm and illuminated amber bypass indicator. (If other indicators are illuminated, refer to

Troubleshooting on page 53). 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.

2.8.3 Battery Mode

The 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 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

availab le.

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 prompt has been acknowledged, the screen showing the estimated battery run time and battery capacity will be visible. Refer to

Troubleshooting on page 53.

For approximate battery run times, refer to .

NOTICE

Risk of loss of power to the connected load. Can cause equipment damage.

Turning Off the 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

Configuration Program on page 44).

2.8.4 Battery Recharge Mode

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


18

2.8.5 Frequency Converter Mode

All models of the 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.”

WARNING! 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.

2.8.6 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.

3 Pull out battery pack with handle.

6. Unpack the new internal battery pack. Take care not to destroy the packing.

Compare the new and old internal battery pack to make sure they are the same type and

model. If so, proceed with 7. If they are different, stop and contact your Vertiv™ representative,

or Technical Support.

7. Line up and slide in the new internal battery pack.

8. Reconnect the battery plug and battery receptacle.

9. Push the battery wire and internal battery pack back into the UPS.

10. Reattach the front battery door with the 6 screws.

11. Reattach the front plastic bezel cover to the UPS.

NOTE: The internal battery pack is hot-swappable. However, caution should be exercised because during this procedure the load is unprotected from disturbances and power outages. 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.

7.2 Battery Charging

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

If the GXT4 will be stored for a long time, We recommend connecting the UPS to input power for at least

24 hours every 4 to 6 months to ensure full recharge of the batteries.


51

7.3 Precautions

Although the Liebert GXT4 is 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 GXT4 before cleaning it.


• 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 GXT4.

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

7.4 Checking UPS Status

We recommend checking the UPS operation status every six months.

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

• Check if 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 Vertiv™ representative or Technical

Support.

• Check if the battery is discharging: When the utility input is normal, the battery should not discharge. If the UPS is operating in Battery Mode, stop and contact your Vertiv™ representative or Technical Support.

7.5 Checking UPS Functions

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

We recommend checking the UPS functions once every 6 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 alarm 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 battery self-test. Check to determine whether the battery is operating normally. If not, stop and contact your Vertiv™ representative or Technical Support.

8.2 Troubleshooting UPS Issues

In the event of an issue with the UPS, refer to the following table to determine the cause and solution. If the fault persists, contact Vertiv™ Technical Support. See

Technical Support on page 63

Table 8.3 Troubleshooting table

PROBLEM CAUSE SOLUTION

UPS is short-circuited or overloaded

UPS fails to start

Batteries are not charged enough or not connected

Ensure UPS is Off. Disconnect all loads and ensure nothing is lodged in output receptacles. Ensure loads are not defective or shorted internally.

Check to ensure the internal battery is connected. If it is not, make the connection and try to start the unit. If the battery is connected, leave the UPS connected to input power for 24 hours to recharge batteries, then try to start the unit.

Battery indicator is illuminated

UPS has reduced battery backup time

Battery indicator is flashing.

Bypass indicator is flashing.

UPS is not plugged in

UPS input protection fuse has blown/opened

UPS is operating from battery mode. Ensure UPS is securely plugged into the wall receptacle.

UPS is operating from battery mode. Save data and close applications. Replace UPS input fuse, then restart UPS.

Mains power is out of tolerance

UPS is operating from battery mode. Save data and close applications. Ensure mains supply voltage is within acceptable limits for UPS.

Batteries are not fully charged Keep UPS plugged in continuously at least 24 hours to recharge batteries.

UPS is overloaded Check load level indicator and reduce the load on the UPS.

Batteries may not be able to hold a full charge due to age

Replace batteries. Contact your local dealer, Vertiv™ representative or Technical Support for replacement battery kit.

Battery source is not available; continuous horn.

Check battery connections, completely power down and restart UPS.

NOTE: If the battery circuit opens while the UPS is running, it will be detected when the next battery test is performed.

Because the voltage or frequency is outside acceptable limits, the bypass is disabled.

The AC input powers the PFC input and serves as the bypass source. If the AC is present but the voltage or frequency exceeds the acceptable range for safe operation with a load, the bypass will be disabled and this indicator will flash, indicating that the bypass is unavailable.

9.1 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 run time 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.
