Figure 1-13 Basic Operating Principle Diagram

Vertiv | Liebert® GXT5™ | Installer/User Guide 15

Table 1-2 Major Components

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 Battery Charger Regulates input AC power to continuously float-charge the batteries� Batteries are charged when the UPS is plugged

in, even when not powered-on�

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 eiciency and voltage, thus increasing reliability�

5

Rectifier/Power

Factor

Correction

(PFC) Circuit

In normal operation, 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

eicient use of utility power and reduces reflected harmonic distortion making cleaner power available to devices

that are not protected by the UPS�

6 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�

7 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 44�

8 Outlet group Output receptacles�

1.7.1. Maintenance Bypass

On 5-kVA to 10-kVA models, the UPS includes manual maintenance bypass in a removable section of the rear of

the UPS� Maintenance bypass keeps connected equipment powered with utility power and allows replacement of

the UPS in the event of a UPS malfunction�

NOTE: The bypass power path does not protect the connected equipment from disturbances in the utility

power supply.

GXT5 Description16

1.8. UPS States and Operating Modes

NOTE: See LED Indicators on page 49, for description of the run-indicator and alarm-indicator LEDs

mentioned in this section.

1.8.1. 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� Figure 1-14 shows the diagram of

normal mode�

1.8.2. 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 “Flow” screen displays “On Bypass�” Figure 1-15 shows the diagram

of bypass mode�

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.

1.8.3. 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 “Flow” screen displays “On Battery�” Figure 1-16 shows the

diagram of battery mode�

NOTE: The batteries are fully-charged before shipment. However, transportation and storage inevitably

cause some loss of capacity. To ensure adequate back-up time, it is recommended to charge the batteries for

atleast 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.

Vertiv | Liebert® GXT5™ | Installer/User Guide 19

1.8.4. ECO Mode

NOTE: ECO mode is only available on a single-UPS system.

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 and

therefore the load will shut down.

1.8.5. Maintenance Bypass Mode

Integrated maintenance bypass is available on 5 kVA or larger UPS models� For smaller models, an optional

MicroPOD may be purchased to provide this functionality if needed�

NOTE: 5-kVA to 10-kVA models include a circuit breaker to switch the load to bypass. On 16-kVA to 20-kVA

models, a dry contact may be used to trigger maintenance bypass.

Used when the UPS requires maintenance or repair, Maintenance-bypass mode powers the connected equipment

with utility power while electrically isolating the internal UPS components�

NOTICE

• Risk of power interruption� Can damage the connected equipment�

• If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode, the UPS

may shut down without notice and shut-o output power to the load�

NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit http://www.

Vertiv.com/en-us/support/ or contact your local Vertiv representative.

2.7.3. Connecting a Remote Emergency Power-o (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 5, 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-o 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 o the UPS input power� When the REPO switch trips, the UPS

generates an alarm and immediately cuts-o 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�

To make the cable for the REPO connection:

Figure 2-12 below, shows the cable required to make the connection� We recommend using 18 AWG to 22 AWG

(0�82 mm2 to 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 2-12 below�

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

2.8. Installing a Parallel System

10-kVA, 16-kVA, and 20-kVA models may be configured in a parallel system� The UPS parallel system provides

support to the following options:

• 3 active systems

• 2 active systems

• 2 active systems plus 1 redundant system

• 1 active system plus 1 redundant system

All electrical requirements, including external-distribution panel and branch circuit breaker, apply to each UPS in

a parallel system, which are then connected in ring configuration for redundancy and additional reliability� System

load information can be accessed via any controller/display in the system�

Installation38

The following are requirements for the parallel-connected system:

• Each UPS must have the same capacity and must be connected to the same mains/utility source�

• If a residual-current detector (RCD) is required, if must be correctly-set and installed before the same

neutral-line input terminal� See safety and regulatory information, available at https://www�vertiv�com/

ComplianceRegulatoryInfo�

• The output of each ups must be connected to the same output bus�

• The parameter configuration for each UPS must be identical�

• Because the parallel system is not fitted with auxiliary-contact detection devices for the output circuit breaker

or the maintenance-bypass circuit breaker of each UPS, You must strictly-follow the procedures for transferring

between operating modes when removing a single UPS from the parallel system before maintenance and when

adding a single UPS after maintenance� Failure to observe the procedures may aect the reliability of the load

power supply�

Figure 2-13 on the next page shows an example of the 10-kVA model connected as a 2 + 1 parallel system connected

in a ring configuration�

NOTE: 8-kVA and lower models do not support paralleling at this time.

NOTE: You must use Vertiv parallel cables for the connection.

NOTE: If a fault occurs during parallel-system operation, shut-o the system and make sure the cables are

connected correctly, see Figure 2-13 on the next page.

CAUTION! Risk of improper disconnection

Can equipment damage. Do not disconnect parallel-system cables while the system is operating.
