1.5 Major Internal Components and Operating Principle

Figure 1.6 on the next page, shows the UPSoperating principle. Table 1.2 on page9, describes the

function of the major components in the UPS.

NOTE: Figure 1.6 on the next page, is one example of basic operation.

Figure 1.6 Basic Operating Principle Diagram

Vertiv | Liebert® GXT5™ Installer/User Guide

ITEM COMPONENT OPERATION/FUNCTION

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.

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.

2.7.3 Connecting a Remote Emergency Power-off (REPO) Switch

The UPS includes an EPO connection in the dry-contact port. See the appropriate figure for your model in

Rear Panels on page4, for the location of the port.

UPS ships with a REPO jumper installed, allowing the UPS to operate as a normally-closed switch system

(fail-safe). Opening the circuit disables the UPS. To connect a REPOswitch that opens the circuit to shut

down the rectifier and inverter and power-off the UPS, use a cable from the remote switch to plug into the

REPO-port on the UPS.

In normal conditions, the REPO switch cannot cut off the UPS input power. When the REPO switch trips,

the UPS generates an alarm and immediately cuts-off output power. When the emergency condition is

resolved, the UPS will not return to normal operation until you reset the REPO switch and manually power-

on the UPS.

2 Installation 17

To make the cable for the REPO connection:

Figure 2.4 below, shows the cable required to make the connection. We recommend using 18AWG to

22AWG (0.82mm2to 0.33mm2) copper-core cable.

1. Remove the insulation from the end of two cables.

2. Insert the stripped end into the plug terminals 1 and 2 respectively, then press down the

terminals. Make sure that the cables are secure in the plug to prevent failure because of loose

contact.

To connect a UPS to the REPO switch

CAUTION: To maintain safety (SELV) barriers and electromagnetic compatibility, signal cables

should be shielded and run separately from power cables.

1. Connect one end of the cable to the remote switch, see Figure 2.4 below.

2. Remove the factory-installed jumper from pins 7 and 8 of the dry-contact port on the UPS

3. Connect the plug to pins 7 and 8.

3 OPERATING THE UPS

WARNING! Risk of electric shock. Can cause injury or death. Hazardous mains and/or battery

voltage exists behind the protective cover No user accessible parts are located behind the

protective covers that require a tool for removal. Only qualified service personnel are

authorized to remove such covers. If maintenance for rack is needed, notice that the neutral

line is live.

3.1 Silencingthe Audible Alarm

The audible alarm may sound during UPS operation. To silence the alarm, press and hold the ESC button

for 2seconds. The button is located on the front-panel display, see Operation and Display Panel on

page23.

3.2 Starting-up the UPS

IMPORTANT! Do not start the UPS until after the installation is finished, the system is commissioned

by an authorized engineer, and the external input circuit breakers are closed.

CAUTION: Starting the UPS applies mains/utility power to the output terminals. Make sure that

the load power is safe and ready to accept power. If the load is not ready, isolate the load with

the output terminal.

The UPS starts in Normal Mode.

To start the UPS:

1. If included on your UPS model, make sure the maintenance-bypass switch is in the open “OFF”

position and that the guard is secured in place.

2. Ensure that the REPO connector on the rear of the unit has a jumper between pins 7-8 or that

it is properly wired to an Emergency Power- Off circuit (normally closed).

3. Make sure the breaker supplying power to the UPS is closed, and close the input breaker on

the rear of the UPS.

4. If included on your UPS model, close the bypass breaker on the rear of the UPS

5. Close all output breakers on the rear of the UPS (or in an external panel board, if used).

6. Power-on the UPS by pressing and holding the power button on the operation and display

panel until the confirmation dialog appears. Use the Up/ Down arrows to select YES, then press

Enter.

7. If this is the first-time start-up of the UPS, the Start-up Guidance wizard opens to set the basic

parameters of the UPS. Follow the prompts.

For detailed description of UPS display functions and settings, see Operation and Display Panel

on page23.

3 Operating the UPS 21

3.3 Transferring to Battery Mode

The UPS operates in Normal mode unless the mains/utility power fails or it is performing a battery self test,

then it automatically transfers to Battery mode for the back-up time available or the mains/utility power is

restored. Once input power is restored, the UPS returns to Normal mode.

NOTE: Battery back-up run times are listed in Battery Run Times on page54.

3.4 Transferring from Normal to Bypass Mode

Press and hold the power button for 2 seconds.

•If the bypass power is within normal operating range, the option to continue to Bypass mode or

turn-off the UPS displays:

a. Use the arrow buttons to select To the Bypass, and press Enter.

b. Use the arrow buttons to select No or Yes, then press Enter to confirm.

•If the bypass power is outside normal operating range, do not transfer to Bypass mode.

3.5 Transferring from Bypass to Normal Mode

Press and hold the power button for 2 seconds.

•If the UPS is operating normally, without faults, the option to continue to turn-on or turn-off the

UPS displays:

a. Use the arrow buttons to select Turn on UPS, and press Enter.

b. Use the arrow buttons to select No or Yes, then press Enter to confirm.

NOTE: The UPS automatically switches back to normal mode after an "overheated" or "overloaded"

fault is cleared and normal power is restored.

3.6 Shutting-down the UPS Completely

WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote

electric power supplies before working with the UPS. Ensure that the unit is shut down and

power has been disconnected before beginning any maintenance.

Transfer to Bypass mode, see Transferring from Normal to Bypass Mode above. Then, if power to the load

is not needed, open the main-input circuit breaker.

3.7 Remote Emergency Power-off (REPO)

REPO turns off the UPS in emergency conditions such as fire or flood. When an emergency occurs, the

REPO switch turns off the rectifier and inverter and stops powering the load immediately. The battery

stops charging and discharging.

To manually power-off in an emergency, disconnect the terminal connecting the REPO port on the rear of

the UPS.

If mains/utility power is present, the UPS control circuit remains active even though output power is

disabled. To remove all mains/utility power, disconnect the external main-input MCB.

5 MAINTENANCE

WARNING! Risk of electric shock. Can cause equipment damage, injury and death. A battery

can present a risk of electrical shock and high short-circuit current.

WARNING! Risk of electric shock. Can cause injury or death. Hazardous mains and/or battery

voltage exists behind the protective cover No user accessible parts are located behind the

protective covers that require a tool for removal. Only qualified service personnel are

authorized to remove such covers. If maintenance for rack is needed, notice that the neutral

line is live.

Observe the following precautions when working on batteries:

•Remove watches, rings and other metal objects.

•Use tools with insulated handles.

•Wear rubber gloves and boots.

•Do not lay tools or metal parts on top of batteries.

•Disconnect charging source prior to connecting or disconnecting battery terminals.

•If the battery kit is damaged in any way or shows signs of leakage, contact your Vertiv

representative immediately.

•Handle, transport, and recycle batteries in accordance with local regulations.

•Determine if the battery is inadvertently grounded. If it is inadvertently grounded, remove the

source of the ground. Contact with any part of a grounded battery can result in electrical

shock. The likelihood of such shock will be reduced if grounds are removed during installation

and maintenance (applicable to a UPS and a remote battery supply not having a grounded

supply circuit).

5.1 Replacing Batteries

WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote

electric power supplies before working with the UPS. Ensure that the unit is shut down and

power has been disconnected before beginning any maintenance.

WARNING! Risk of electric shock and explosion. Can cause equipment damage, injury and

death. Do not dispose of the battery in a fire. The battery may explode. Do not open or damage

the battery. Released electrolyte is toxic and is harmful to skin and eyes. If electrolyte comes

into contact with the skin, wash the affected area immediately with plenty of clean water and

get medical attention.

WARNING! Risk of electric shock. Can cause equipment damage, injury and death. A battery

can present a risk of electrical shock and high short-circuit current.

5 Maintenance 43

WARNING! Risk of explosion. Can cause equipment damage, injury and death. A battery can

explode if the battery is replaced by an incorrect type. Dispose of used batteries according to

the instructions included with the battery-pack.

Read all safety cautions before proceeding. A trained user can replace the internal battery pack when the

UPS is in a restricted access location (such as a rack or server closet). To obtain the appropriate

replacement battery pack(s), refer to Table 5.1 below, and contact your local dealer or Vertiv

representative.

Table 5.1 Replacement Battery-pack Model Numbers

To replace a battery pack:

NOTE: The internal battery pack is hot-swappable. However, you must exercise caution 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.

1. Press the button on the left-front of the UPS front panel, and pull the panel open, then, loosen

and remove the screw from the battery door, see Figure 5.1 on the facing page.

2. Lay the battery door and screw aside for reassembly.

3. Grasp the battery handle, and pull out the battery pack, see Figure 5.1 on the facing page.

4. Unpack the replacement battery pack, taking care not to damage the packaging to re-use

when disposing of the old battery.

5. Compare the new and old battery pack to make sure they are the same type and model. If so,

proceed with step 6. If they are different, stop and contact your Vertiv representative, or

Technical Support, http://www.Vertiv.com/en-us/support/.

6. Line-up and slowly push-in each replacement battery pack. The battery is fully-inserted if the

battery door fits flush against the UPS.

7. Re-attach the battery door with the screw, and replace the front cover.

8. Activate the new battery pack(s) using the operating/display panel:

NOTE: The display menus and functions are described in Operation and Display Panel on page23.

•From the main menu, select Settings, then the Monitoring tab and verify that the date

and time are correct. If the date or time need correction, see Setting the Date and Time

on page42.

5.2 Charging Batteries

The batteries are valve-regulated, non-spillable, lead acid and should be kept charged to attain their

design life. The UPS charges the batteries continuously when it is connected to the utility input power.

If the UPS 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.

5 Maintenance 45

5.3 Checking UPS Operation

NOTE: Operation-check procedures may interrupt power supply to the connected load.

We recommend checking the UPS operation once every 6months.

Back-up the load data before conducting the check.

1. Press the power button to check the indicators and display function.

2. Check for alarm or fault indicators on the operation/display panel.

3. Make sure that there are no audible or silenced alarms.

4. Select the Setting menu, and look at the log for alarm and fault history.

5. Check the operating mode for Normalmode. If the UPS is operating in Bypass mode, contact

Vertiv Technical Support.

6. Check to see if batteries are discharging (operating in Battery mode) and utility power is

normal. If so, contact Vertiv Technical Support.

5.4 Cleaning the UPS

WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote

electric power supplies before working with the UPS. Ensure that the unit is shut down and

power has been disconnected before beginning any maintenance.

WARNING! Risk of electric shock. Can cause injury or death. Hazardous mains and/or battery
