INTRODUCTION AND SYSTEM DESCRIPTION
Congratulations on your choice of the UPStation GXT™ Uninterruptible Power
System (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, which may interrupt computer operations, cause data loss, or even
damage equipment. The UPStation GXT protects equipment from these
disturbances.
The UPStation GXT is a compact, “on-line” UPS. An “on-line” UPS continuously
conditions and regulates its output voltage, whether the mains power is present
or not. It supplies connected equipment with clean sinewave power. Sensitive
electronic equipment operates best from sinewave power. The GXT
6000/10000T-230X models have an additional output isolation transformer.
For ease of use, the UPStation GXT contains a light emitting diode (LED) display
to indicate either “load percentage” or “battery capacity” depending upon the
mode of operation. It also provides self-diagnostics, a combination On/Alarm
Silence/Manual Battery Test button, a combination Off/Bypass button, and two
levels of alarms when the unit is operating on battery.
The UPStation GXT has an interface port for communications between the UPS
and a LAN server or other computer system. This port provides detailed
operating information including voltages, currents, and alarm status to the host
system when used in conjunction with the SiteNet® 2 software. SiteNet® 2
software can also remotely control UPS operation.

RECTIFIER/POWER FACTOR CORRECTION (PFC) CIRCUIT
In normal operation, the rectifier/power factor correction (PFC) circuit converts
mains 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 sinewave input current achieves two objectives: the mains power
is used as efficiently as possible by the UPS, and the amount of distortion
reflected on the mains is reduced. This results in cleaner power being available
to other devices in the building not being protected by the UPStation GXT.
INVERTER
In normal operation, the inverter utilises the DC output of the power factor
correction circuit and “inverts” it into precise, regulated sinewave AC power.
Upon a mains power failure, the inverter receives its required energy from the
battery through the rectifier / PFC. In both modes of the operation, the UPS
inverter is on-line and continuously generating clean, precise, regulated AC
output power.
BATTERY CHARGER
The battery charger utilises energy from the Rectifier / PFC and precisely
regulates it to continuously “float” charge the battery system. The battery system
charges whenever the UPStation GXT is connected to mains power.
BATTERY
The UPStation GXT employs valve regulated, non-spillable, lead acid batteries.
At typical room temperatures and with the UPS float charging, the battery system
will last many years. Optional external battery cabinets are available to provide
extended run times.
STATIC BYPASS
The UPStation GXT provides an alternate path for mains power to the connected
load, in the unlikely event of a UPS malfunction. Should the UPS have an
overload, over temperature, or UPS failure condition, the UPS automatically
transfers the connected load to BYPASS providing the bypass voltage is within
specification. BYPASS operation is indicated by an alarm and an illuminated
BYPASS LED (other LED’s may be illuminated to indicate the diagnosed
problem). To manually transfer the connected load from the inverter to BYPASS
power, press the output OFF button once.
NOTE: The BYPASS power path does NOT protect the connected equipment
from disturbances on the mains supply and its range of operation is limited to +/-
15% of the nominal input supply voltage.
AUTO RE-START
Upon restoration of the mains AC power after a mains power outage and
complete battery discharge, the UPS will automatically restart and supply power
to the critical load and the battery charger automatically recharges the battery.

OPERATING MODES
NORMAL MODE OPERATION- UPS mode
During normal operation, mains power provides energy to the UPS. The filters,
the 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 LED’s 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 sound an alarm.
Normal Mode Operation at
51-75% loading
The display template indicates the
percentage of load on the UPS output.
BATTERY MODE OPERATION
Battery mode occurs in event of an
extreme input voltage condition or
complete mains failure. The battery
system supplies power through the
DC-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
2 beeps every 5 seconds when battery
runs low (approximately 2 minutes
remaining). The AC Input LED will
extinguish, and the Battery LED will
illuminate to warn that a mains problem
Battery Mode Operation at
81-100% battery capacity
has occurred. Each load/battery level indicator represents a 20% capacity level.
As capacity decreases, fewer indicators remain illuminated. Refer to the
Troubleshooting Guide.
To increase this time, turn off non-essential pieces of equipment (such as idle
computers and monitors) or add an optional external battery cabinet.
CAUTION: Turning off the UPS while in battery mode will result in loss of output
power.
Once mains power is restored, the UPS resumes normal operation. At this time,
the Battery Charger begins recharging the battery.

ELECTRICAL INSTALLATION CONSIDERATIONS
This UPS must be installed by competent electrical personnel and wired in
accordance with local/national electrical codes.
The following information is provided for your guidance.
WARNING
HIGH EARTH LEAKAGE CURRENT- EARTH CONNECTION IS
ESSENTIAL BEFORE CONNECTING THE MAINS SUPPLY. Earth in
accordance with local electrical codes.
CAUTION
This UPS is fitted with EMC suppression filters. Earth leakage
exceeds 35mA. Transient and steady state earth leakage currents,
which may occur when starting the UPS, should be taken into
account when selecting instantaneous RCCB or RCCD devices. Note
also that the earth leakage currents of the load will be carried by this
RCCB or RCCD.
WARNING
This UPS does not incorporate automatic backfeed protection.
A warning label must be fitted to all primary power isolators stating:
ISOLATE UNINTERRUPTIBLE POWER SYSTEM BEFORE WORKING ON
THIS CIRCUIT.
On start-up, the UPS will take a half cycle inrush current of up to 3 times the
rated current. This must be taken into account when selecting the overload
protection device at the input mains supply distribution point. To avoid random
tripping on start-up, we recommend that the input mains supply be protected with
an MCB capable of withstanding this initial inrush. An MCB specified as being
“TYPE 4” (British standard) or “CURVE D” (IEC standard) is suitable for this
purpose.
The mains input supply cable must be connected to the UPS via a wall mounted
double pole circuit breaker, rated to carry the current in table 1 and be capable of
breaking the maximum prospective short circuit current of this branch circuit. The
breaker is to be mounted within two metres of the UPS and be readily accessible
to the operator.

ELECTRICAL CONNECTIONS
The UPS is supplied with an input/output/ battery terminal block assembly on the
rear of the UPS within a cable box. (see outline drawing) The cable box can be
removed to enable knockouts to be removed or new holes drilled, to secure the
cables.
The cable sizes and distribution methods used during installation are subject to
local/ national electrical codes of practice , and therefore are not detailed here.
However, table 1 gives details of the input current and the UPS rating plate gives
details of the output current according to output voltage selected.
The terminals will accept wire sizes up to the values below:
GXT6000 = 10 mm2

Stabilisers/Levelling Feet
When the UPS is located in its final position before or after wiring, it is necessary
to fit stabiliser brackets and, if necessary, adjust the levelling feet. If the UPS is
wired using a rigid wiring system, then movement of the UPS must be prevented
by winding down the 4 levelling feet under the UPS as shown below. For UPS
wired with flexible cables, this is optional. Note- Access to the levelling feet is
obstructed by the stabiliser brackets, on the GXT10000 models.
Adjust the levelling feet as necessary using
a
12mm open ended
spanner/wrench. DO NOT LOOSEN THE LARGER NUT ABOVE, AS THIS
FIXES THE LEVELLING FEET TO THE CHASSIS.
Attach the stabilising brackets as follows.
GXT6000 models:
1. Using a Phillips-head screwdriver, remove the screws(4) from each of the
bottom corners of the side panels.
2. Attach the stabilising brackets to each corner using screws just removed.
GXT10000 models:
1. Using a Phillips-head screwdriver, remove the three inner-most screws at
the base of both side panels.

SEGREGATED AND RUN SEPARATE FROM ALL OTHER POWER CABLES,
BY 25mm WHERE APPLICABLE.
UPS Remote shutdown option.
Shorting pins 5 and 6 on the DB9 connector will shutdown the UPS output in any
mode of operation. Removing the short circuit, the UPS will automatically auto-
restart.
Where there is a requirement for a remote shutdown of the UPS to meet fire or
other local safety codes, it is necessary to interrupt, at the same time with the
same pushbutton, all mains input supplies to the UPS. The pushbutton that
provides the UPS remote shutdown must be of the stay-down type ( Latching) to
keep a short circuit on pins 5 and 6 until mechanically unlatched by hand.
Note ; The wiring for remote stop contacts pins 5 and 6 of the DB9 connector are
defined as SELV . When connecting to a stop button interfacing with other mains
emergency stop circuits, keep wiring segregated from other power wiring.

COMMISSIONING THE UPS
Output Voltage Selector Switches
The Output Voltage Selector Switches, located on the rear of the UPS, are
designed to allow selecting or changing the desired output voltage to match the
mains. The settings to choose from are 208, 220, 230, and 240 VAC output.
230 & 230X Units
208 V
220 V
230 V
240 V
áá - both switches up
áâ - first switch up, second down
ââ - both switches down (Factory Default)
âá - first switch down, second up
NOTE: NEVER change the switch settings while UPS is on and powering
connected loads.
NOTE: Setting output voltage to 208 VAC will cause UPS unit to be derated to
90% of the VA and Watt rating listed in specification section.
1. Adjust the output voltage switch settings to the desired value.
2. Follow the instructions for Powering up the UPS referenced earlier in this
manual. Sequence through the operating modes, using the front panel
pushbuttons, in accordance with operating instructions to check functionality
of the UPS.
3. Set the UPS to UPS mode. Check on the output terminals of the UPS, for the
correct output voltage for the voltage rating of the intended loads.
4. Check operation of the remote shutdown circuit (If fitted).
5. In UPS mode, power up customers load and check that it is within the UPS
rating by observing the front panel LED’s
6. In UPS mode, press the UPS ON/ALARM /BATTERY TEST pushbutton to
carry out battery test and ensure the load can be supported. Note- Full
battery capacity will not be available until a battery recharge cycle has been
completed.
The UPS is now ready for service In case of problems refer to the fault finding
section or call your local distributor for advice.

LIMITED WARRANTY
Liebert Corporation extends the following LIMITED WARRANTY to
the purchaser and to its customer (collectively referred to as the
"Purchaser"): the enclosed Uninterruptible Power System (UPS) and
components are free from defects in materials and workmanship
under normal use, service, and maintenance FOR A PERIOD OF
TWO YEARS FROM THE DATE OF ORIGINAL PURCHASE from
Liebert or the Liebert dealer or retailer. THE FOREGOING
WARRANTY IS THE ONLY WARRANTY GIVEN AND NO OTHER
WARANTY IS PROVIDED, EXPRESS OR IMPLIED, INCLUDING
WITHOUT LIMITATION, MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE. Certain aspects of disclaimers are not
applicable to consumer products acquired by individuals and used for
personal, family, or household purposes (as distinguished from
industrial or other purposes). Local laws may not allow limitations on
how long an implied warranty lasts, so the above limitation may not
apply to you. This warranty gives you specific legal rights, and you
may have other rights which vary according to local law.
Certain repairs or services are the responsibility of the Purchaser and
the Purchaser is expected to pay for them. This warranty does not
extend either to products with removed or altered serial numbers or to
any losses or damages due to act of God or source external to the
product, misuse, accident, abuse, neglect, negligence, unauthorised
modification, alteration, or repair, use beyond rated capacity, or
improper installation, maintenance, application or use, including,
without limitation, use in a manner contrary to the accompanying
instructions or applicable codes. WARNING: Warranty is void if the
battery is allowed to discharge below the minimum battery cut-off
point. The battery must be recharged every four (4) to six (6) months
when not in use.
If the UPS fails to conform with the above warranty within the two year
warranty period, Liebert will repair or replace the UPS, at Liebert's
option. Repairs or replacements are warranted for the remainder of
the original warranty period. Purchaser, to make a warranty claim,
should call to obtain a Returned Goods Authorisation number and
shipping instructions. Return transportation costs to Liebert are the
responsibility of the Purchaser.
"LIFE SUPPORT" APPLICATIONS
Due to the diversity of applications and considerations to be applied in
each case, Liebert does not recommend or knowingly sells its
products for such use.
The responsibility for risk assessment and management in applications
where the malfunction or failure of the UPS could be reasonably
expected to give rise to a risk of human life shall be the sole
responsibility of the purchaser. Liebert accepts no liability for
