Introduction  
1.0 INTRODUCTION  
Congratulations on your choice of the Liebert GXT2-6000RTL630 Uninterruptible Power Supply  
(UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.  
Upon generation, AC power is clean and stable. However, during transmission and distribution it  
may be subject to voltage sags, spikes or complete power failure that may interrupt computer opera-  
tions, cause data loss or even damage equipment. The GXT2-6000RTL630 protects equipment from  
these disturbances.  
The GXT2-6000RTL630 comes in a nominal power rating of 6000 VA. Complete model specifications  
appear at the end of this manual.  
The GXT2-6000RTL630 is a compact, on-line UPS. An on-line UPS continuously conditions and regu-  
lates its output voltage, whether utility power is present or not. It supplies connected equipment with  
clean sinewave power. Sensitive electronic equipment operates best from sinewave power.  
For ease of use, the GXT2-6000RTL630 features a light-emitting diode (LED) display to indicate both  
load percentage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm  
Silence/Manual Battery Test button, a Standby button, user configurable program, and two levels of  
alarms when the unit is operating on battery.  
The GXT2-6000RTL630 has an interface port for communication between the UPS and a network  
server or other computer systems. This port provides detailed operating information including volt-  
ages, currents, and alarm status to the host system when used in conjunction with Liebert Multi-  
Link™ software. MultiLink software can also remotely control UPS operation.

Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters  
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 util-  
ity line and keep the sensitive equipment protected.  
Rectifier/Power Factor Correction (PFC) Circuit  
In normal operation, the rectifier/power factor correction (PFC) circuit converts utility 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 utility power is used as efficiently as possible by the UPS.  
• The amount of distortion reflected on the utility is reduced.  
This results in cleaner power being available to other devices in the building not being protected by  
the GXT2-6000RTL630.  
2.3  
2.4  
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 utility power failure, the inverter  
receives its required energy from the battery through the DC to DC converter. In both modes of oper-  
ation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output  
power.  
Battery Charger  
The battery charger utilizes energy from the utility power and precisely regulates it to continuously  
float charge the batteries. The batteries are being charged whenever the GXT2-6000RTL630 is con-  
nected to utility power.

2.7  
DC-to-DC Converter  
The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the opti-  
mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti-  
mum efficiency and voltage, thus increasing reliability.  
Battery  
The GXT2-6000RTL630 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain bat-  
tery design life, operate the UPS in an ambient temperature of 68°F to 77°F (20°C to 25°C). Optional  
external battery cabinets are available to extend battery run times.  
Dynamic Bypass  
The GXT2-6000RTL630 provides an alternate path for utility power to the connected load in the  
unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature, or 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 button once.  
NOTE  
The bypass power path does NOT protect the connected equipment from disturbances  
in the utility supply.

Installation and Configuration  
5.0 INSTALLATION AND CONFIGURATION  
Do NOT attempt to start the UPS, turn on any circuit breaker or energize the input power until  
instructed to do so in 6.0 - Initial Start-Up and Electrical Checks.  
Visually inspect the UPS for freight damage. Report any damage to the carrier and your local dealer  
or Liebert representative.  
CAUTION  
!
The UPS is heavy (see 13.0 - Specifications). Take proper precautions  
when lifting or moving it.  
Install the UPS indoors in a controlled environment, where it cannot be accidentally turned off. Place  
it where air flows unrestricted around the unit. The installation location must be free of water, flam-  
mable liquids, gases, corrosives and conductive contaminants. Maintain a minimum clearance of  
4 inches (100mm) in the front and rear of the UPS. Maintain an ambient temperature range of  
32-104°F (0 to 40°C).  
NOTE  
UPS operation in sustained temperatures above 77°F (25°C) reduces battery life.  
5.1  
Install the Main Cabinet  
The GXT2-6000RTL630 may be installed in either a tower configuration or in a rack, depending on  
available space and use considerations. Determine the type of installation and follow the appropriate  
instructions in either 5.1.1 - Tower UPS Installation or 5.1.2 - Rack-Mount UPS Installation.  
5.1.1 Tower UPS Installation

Installation and Configuration  
5.4.2 Distribution Box Electrical Connections  
Electrical connections are made through a removable power distribution box that attaches to the rear  
of the UPS.  
The installer must provide a 30A branch circuit breaker, with NEMA L6-30R receptacle. The Input  
circuit breaker on the distribution box and the Output circuit breaker on the rear fixed-panel of the  
UPS disconnect all power between the main cabinet and the distribution box.  
Models equipped with a manual bypass switch pass bypass power directly to the bypass switch from  
the input power cord. The input circuit breaker on the distribution box does not disconnect power  
from the manual bypass switch.

Operating Instructions  
9.0 OPERATING INSTRUCTIONS  
9.1  
Normal Mode Operation  
During normal operation, utility power provides energy to the  
UPS. The filters, power factor correction circuit and the inverter  
process this power to provide computer grade power to connected  
loads. The UPS maintains the batteries in a fully charged state.  
The four green load level LEDs indicate an approximate level of  
load in 25% increments. If the UPS becomes loaded beyond full  
rating, the fifth (amber) LED indicator will illuminate and the  
UPS will sound an audible alarm. The display template indicates  
the percentage of load (10% of load shown in example) on the UPS  
output.

Load at 10%  
9.2  
Battery Mode Operation  
Battery mode occurs in event of an extreme input voltage condition  
or complete utility failure. The battery system supplies power  
through the DC to DC converter to the inverter to generate power  
for the connected load. During battery mode an alarm sounds  
every 10 seconds. This will change to two beeps every 5 seconds  
when the battery runs low (approximately 2 minutes remaining,  
but this is user configurable). The AC Input LED will extinguish,  
and the Battery LED will illuminate to warn that a utility problem  
has occurred. Each battery level indicator represents a 20% capac-  
ity level. As capacity decreases, fewer indicators remain illumi-  
nated. Refer to 12.0 - Troubleshooting. For approximate battery  
Battery Mode Operation

run times, refer to Table 5. These times are approximate, based on resistive load and an ambient  
temperature of 77°F (25°C). To increase this time, turn off non-essential pieces of equipment (such as  
idle computers and monitors) or add the optional external battery cabinet.  
CAUTION  
!
Turning OFF the UPS while in it is battery mode will cut off output power.  
9.3  
Bypass Mode Operation  
Bypass mode occurs when the OFF button is pressed once while  
the UPS is in Normal Mode. During bypass operation, utility  
power provides energy to the UPS. The utility power bypasses the  
inverter and provides power for the connected load.

the percentage of load (26-50% of load shown in the example above) on the UPS output.  
9.4  
Battery Recharge Mode  
Once utility power is restored, the UPS resumes normal operation. At this time, the Battery Charger  
begins recharging.

* Maximum voltage and current on pins 1, 7, 8 and 9 are 60VDC and 10.0 mA  
10.2 Pin 4 - Remote Shutdown on Battery  
1. This pin is functional only when the UPS is in battery mode. If the UPS is being powered by  
utility power, Pin 4 will ignore any signal on this pin.  
2. Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes from the serial port using  
Liebert's contact closure cable. It cannot be used with just a contact closure unless the relay is  
used to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or greater is required to signal  
a shutdown. Signals for less than 1.5 seconds will be ignored. After Pin 4 receives a shutdown  
signal for 1.5 seconds, the command cannot be canceled.  
3. A battery shutdown signal on Pin 4 will NOT cause an immediate Shutdown. A shutdown signal  
will start a 2-minute shutdown timer. The timer cannot be stopped. After 2 minutes, the UPS will  
shut down.  
4. If utility power returns during the 2-minute timer countdown, the shutdown timer will continue  
until the end of 2 minutes and the UPS will turn OFF. The UPS must remain OFF for at least  
10 seconds even if AC input power Returns before the UPS turns OFF. This serves to reset and  
restart the server.  
Whether the UPS turns back ON when power is restored depends on the auto-restart setting: enabled  
or disabled.  
If the auto-restart is disabled, the UPS will not restart after performing the 2-minute shutdown  
delay.

Communications  
10.3 UPS Intelligent Communications  
The GXT2-6000RTL630 is equipped with two Intellislot® ports to provide advanced communication  
and monitoring options.  
The Intellislot port closer to the corner of the UPS chassis is the serial card slot. This Intellislot port is  
used for the OCWEBCARD and the USBCARD. The other Intellislot port is used for  
RELAYCARD-INT or the MULTIPORT Card.  
Liebert’s OCWEBCARD  
DB9 (RS232) port  
covered  
NOTE  
The OCWEBCARD DB9 serial port cable should be used only for the initial card setup. Remove  
the cable after setup is complete.  
When the DB9 OCWEBCARD serial port cable is removed, the OCWEBCARD DB9 connector  
needs to be covered. The DB9 cover is included with the UPS.  
Liebert's MultiLink software continually monitors the UPS and can shut down your computer or  
server in the event of an extended power failure.  
MultiLink can also be configured for use without the serial cable when the Intellislot SNMP/Web card  
is installed in the UPS. Additionally, MultiLink can be configured to coordinate shutdown across the  
network with other computers running MultiLink when you purchase a MultiLink License Kit. For  
more information about the Intellislot SNMP/Web Card and MultiLink license Kits, visit our Web site  
(www.liebert.com) or contact your local dealer or Liebert representative.  
Several option cards are available for use in the Intellislot port of the GXT2-6000RTL630. The Intel-  
lislot SNMP/Web Card provides SNMP and Web-based monitoring and control of the UPS across the  
network.  
The Intellislot MultiPort 4 Card allows you to install MultiLink software on four computers and coor-  
dinate shutdown in the event of a power failure.  
The Intellislot Relay Card provides dry contact relay outputs for custom wired applications and deliv-  
ers support for built-in shutdown for AS/400 systems.  
CAUTION  
!
To maintain safety (SELV) barriers and for electromagnetic compatibility, signal cables  
should be segregated and run separate from all other power cables, where applicable.

Maintenance  
11.0 MAINTENANCE  
11.1 Internal Battery  
The GXT2-6000RTL630 requires very little maintenance. The batteries are valve-regulated, non-  
spillable, flame retardant, lead acid, and should be kept charged to obtain their designed life. The  
UPS continuously charges the batteries when connected to the utility supply.  
When storing the UPS for any length of time, it is essential to plug the UPS in for at least 24 hours  
every four to six months to ensure full recharge of the batteries. Failure to recharge the batteries peri-  
odically will result in permanent degradation of battery capacity.

Troubleshooting  
12.0.1 Auto-Learning Battery Run Times  
As batteries age, the estimated runtimes may become less accurate. The GXT2-6000RTL630 is pro-  
grammed 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-of-dis-  
charge 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.
