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 opera­tions, 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 regu­lates 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 volt­ages, currents, and alarm status to the host system when used in conjunction with Liebert Multi­Link™ software. MultiLink software can also remotely control UPS operation.

2.1 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 util­ity line and keep the sensitive equipment protected.

2.2 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 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 oper­ation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output
power.

2.4 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 con­nected to utility power.

DISCONTINUED

PRO DU C T

2.5 DC-to-DC Converter

The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the opti­mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti­mum efficiency and voltage, thus increasing reliability.

2.6 Battery

The GXT2-6000RTL630 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain bat­tery 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.

2.7 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.

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, flam­mable 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

Installation and Configuration

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

When using the GXT2-6000RTL630 in a tower configuration, use the included support base (shown
below, left) to stabilize the UPS. If any external battery cabinets are added, they will include spacers
to accommodate the additional cabinets (shown below, right).

Attach Bezels to Top

When used as a tower, the GXT2-6000RTL630 requires bezels attached to the top. To connect the
bezels:

1. Position the UPS so that the battery compartments are on the right side.

7. Insert the equipment, with inner members attached in
Step 5, into the bracket assemblies by inserting the top
and bottom edges of the inner members into the top and
bottom curved tracks of the front members and sliding
the equipment into the rack (see figure at right). Ends of
inner members are tapered to allow the rear of the
equipment to be angled upward before insertion, if space
allows.

Then the rear, bottom edges of the inner members can
be placed into the front edge of the bottom tracks and
the front of the equipment can be tipped up so they are
level to insert the top edges of the inner members before
sliding the equipment into the rack (see figure below
right). The equipment should move smoothly into the
bracket assemblies. If it does not, recheck the alignment
of the front and rear members from Steps 2 and 3.

8. Secure the front of the equipment to the rack mounting
rails to prevent the equipment from sliding out of
position. If securing holes are provided on the front of
the equipment that align with the center holes on the

9.0 OPERATING INSTRUCTIONS

AC INPUT

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.

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% capac­ity level. As capacity decreases, fewer indicators remain illumi­nated. Refer to 12.0 - Troubleshooting. For approximate battery
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 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 (26-50% of load shown in the example above) on the UPS output.

* 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

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.

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

Communications

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 Intel­lislot 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 coor­dinate shutdown in the event of a power failure.

The Intellislot Relay Card provides dry contact relay outputs for custom wired applications and deliv­ers 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.

10.4 Remote Emergency Power Off

The UPS is equipped with a Remote Emergency Power Off (REPO) connector.

The user must supply a means of interfacing with the REPO circuit to allow disconnecting the UPS
input feeder breaker to remove all sources of power to the UPS and connected equipment to comply
with national and local wiring codes and regulations.

11.0 MAINTENANCE

11.1 Internal Battery

The GXT2-6000RTL630 requires very little maintenance. The batteries are valve-regulated, non­spillable, 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 peri­odically will result in permanent degradation of battery capacity.

11.1.1 Internal Battery Replacement

CAUTION

!

A battery can present a risk of electrical shock and high short circuit current. Observe the
following precautions before replacing the batteries:

• Remove rings, watches and other metal objects.

• Use a Phillips (cross-head) screwdriver with insulated grips.

• Do not lay tools or other metal objects on top of the batteries.

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

your local dealer or Liebert representative immediately.

• Do not dispose of batteries in a fire. The batteries may explode.

• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It is

toxic.

Maintenance

1. Remove the 3U battery access panel on the front of
the UPS by loosening the two captive screws
located between the bezels (see illustration at
right).

2. Once the captive screws are loosened, tip the panel
forward and lift to remove it from the main
cabinet.

3. Use a Phillips (cross-head) screwdriver to remove
the screw in the battery retaining bracket on each
battery pack (see illustration at right). Remove the
retaining brackets.

4. Disconnect the battery connectors in the front of
each battery pack.

5. Lift the internal connector out of the way and slide
the battery out of the UPS. Support the weight of
the battery to prevent it from falling.

6. Unpack the new battery assembly, taking care not
to destroy the packing. Compare new and old
battery assemblies to make sure they are the
same. If so, proceed with Step 7; otherwise STOP
and contact your local dealer, Liebert
representative or the Liebert Worldwide Support
Group.

7. Line up and slide in the new replacement battery
pack while holding the internal connector out of
the way.

12.0.1 Auto-Learning Battery Run Times

As batteries age, the estimated runtimes may become less accurate. The GXT2-6000RTL630 is pro­grammed 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.
