1.6 Major Internal Components and Operating Principle
Figure 1.12 below, shows the UPSoperating principle. Table 1.2 on the next page, describes the function
of the major components in the UPS.
NOTE: Figure 1.12 below, is one example of basic operation. The actual I/O connections for the
various models may be divided into different types. See Hardwired Input/Output Connections on
page25.

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 Continuously float-charges the batteries from precisely-regulated utility power whenever the UPS is
plugged in.
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
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.
Table 1.2 Major Components
1 GXT5 Description 13
ITEM COMPONENT OPERATION/FUNCTION
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 page40.
8 Outlet group Output receptacles.
Table 1.2 Major Components (continued)
1.6.1 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.
1.7 UPS States and Operating Modes
NOTE: See LED Indicators on page42, for description of the run-indicator and alarm-indicator LEDs
mentioned in this section.
1.7.1 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
1.13 on the facing page, shows a diagram of normal mode.

1.7.2 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." Figure 1.14 on the next page, shows a 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.

1.7.3 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."
Figure 1.15 on the facing page, shows a 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, 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.

1.7.4 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 ECOmode 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.
1 GXT5 Description 17
1.7.5 Maintenance Bypass Mode
NOTE: 5-kVA to 10-kVA models include an MCB 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-off output power to the load.
NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit

2.6.1 Branch Circuit Breaker
The installer must provide an upstream branch circuit breaker, see Table 2.2 below, for the ratings. The
input circuit breaker on the distribution box and the output circuit breaker on the rear of the power
distribution box disconnect all power between the main cabinet and the distribution box. Figure 2.4 on
the facing page, shows a diagram of the circuit breakers.
Observe the following guidelines and specifications when making the hard-wire input and output
connections:
•Provide circuit-breaker protection according to local codes. The mains disconnect should be
within sight of the UPS or have an appropriate lock-out.
•Maintain service space around the UPS or use flexible conduit.
•Provide output-distributions panels, circuit-breaker protection, or emergency disconnects
according to local codes.
•Do not install input and output wiring in the same conduit.
Models equipped with a manual bypass breaker pass bypass power directly to the bypass breaker from
the input terminal block. The input circuit breaker on the distribution box does not disconnect power
from the manual bypass breaker.

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 page4, 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 REPOswitch 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.
2 Installation 33
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.
To make the cable for the REPO connection:
Figure 2.11 below, shows the cable required to make the connection. We recommend using 18AWG to
33AWG (0.82mm2to 0.33mm2) 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 2.11 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.

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 N+X(1≤N+X≤3,X=0or1) parallel configuration. Nstands for the basic parallel sets, Xstands
for the redundant sets.
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.
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.vertivco.com/ComplianceRegulatoryInfo.
•The output of each ups must be connected to the same output bus.
2 Installation 35
•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 procedure may affect the reliability of the load power supply.
Figure 2.12 below, shows an example of the 10-kVA model connected as a 2+1parallel system connected
in a ring configuration.
NOTE: 8-kVA models do not support parallelling at this time.
NOTE: You must use Vertiv parallel cables for the connection.
NOTE: If a fault occurs during parallel-system operation, shut-off the system and make sure the cables
are connected correctly, see Figure 2.12 below.
CAUTION: Risk of improper disconnection. Can equipment damange. Do not disconnect
parallel-system cables while the system is operating.
