INTRODUCTION Congratulations on your choice of the Liebert GXT2U™ 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 that may interrupt computer operations, cause data loss, or even damage equipment. The Liebert GXT2U protects equipment from these disturbances.
MAJOR COMPONENTS Input L1 Output Dynamic Bypass TVSS & EMI/RFI Filters Rectifier /PFC Inverter L1 DC to DC Converter Battery Charger Battery L2 G L2 G Transient Voltage Surge Suppression 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.
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. Battery The Liebert GXT2U 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).

INSTALLATION Preparation 1. Visually inspect the UPS for freight damage. Report damage to the carrier and your local dealer or Liebert representative. ! CAUTION The UPS is heavy (see Specifications section). Take proper precautions when lifting or moving it. 2. Decide where to place the Liebert GXT2U. Install the UPS indoors in a controlled environment, where it cannot be accidentally turned off.
Rack-Mount UPS Conversion and Installation NOTE When rack mounted, the UPS must be supported by a shelf, brackets or slide rails on each side. The rack mount handles WILL NOT support the weight of the UPS. They are used to move the UPS into and out of the rack. 1. For slide rail installations, first remove the top/side fin. Slide the top/side fin forward, then lift it up to remove. If desired, install the optional rack mount handles that were shipped with the UPS.
Install rear member of each M5 screws bracket assembly into rack enclo- Front rack sure with two (2) M5 screws pro- mounting rails vided in this kit. (See figure at right.) Return flanges on bracket assembly fit to the inside of rack mounting rails. Insert screws loosely (finger-tight) into top and bottom holes of return flange on rear member. Extend bracket assembly by sliding front memRear rack ber forward until it touches the mounting front rack mounting rail.
6. Open grease packet provided in this kit. Apply a 1" long bead of grease four (4) places inside the bottom, curved tracks of front members as shown at right. The grease will allow the equipment to slide into the bracket assemblies more easily. ! Apply grease UPS or battery cabinet Apply grease (inside) CAUTION Lifting equipment into rack may be a two-person job, depending on weight of equipment. See equipment’s user manual. 7.

The unit has two front tower panel overlays. Remove the outer UPS overlay (used for tower installation). This reveals a horizontally oriented front panel overlay for rack mounting. Snap the front bezel back into place. 10.
4. Use the enclosed support bases for the tower option to prevent tip-over. One additional set of support base extensions ships with each external battery cabinet. 5. Connect the supplied external battery cabinet cable to the rear of the external battery cabinet, then to the rear of the UPS. 6. Turn ON the battery breaker on the rear of the external battery cabinet. 7. The UPS is now equipped with additional backup battery run time.
CONTROLS AND INDICATORS All LEDs illuminated for illustrative purposes only. ON/Alarm Silence/Manual Battery Test Button This button controls output power to connected load(s) and has three functions: • ON • Alarm Silence • Manual Battery Test ON - Pressing this button will start up the UPS in order to provide conditioned and protected power. Alarm Silence - To silence alarms, press this button for at least one second.
Standby/Manual Bypass Button This button controls output power to connected load(s) and has dual functions: Standby and Manual Bypass. ! CAUTION While the UPS is in Normal Mode operation, pressing the Standby/ Manual Bypass button once will put the UPS into Bypass Mode. Once the UPS is in Bypass Mode operation, press the Standby/ Manual Bypass button two distinct times (for about one second each time) to turn off the UPS.
Output Voltage Selection The Output Voltage is user configurable and is designed to allow selecting or changing the desired output voltage to match the utility via the Liebert GXT2U Configuration Program provided with the UPS. The settings to choose from are 200, 208, 220, 230, and 240 VAC output. The factory default setting is 208 VAC. ! CAUTION Never change the voltage settings while the UPS is ON and powering connected loads.
OPERATING INSTRUCTIONS Normal Mode Operation AC INPUT BATTERY UPS ON BYPASS Normal Mode Operation at 26-50% 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.
Battery Mode Operation AC INPUT BATTERY UPS ON BYPASS 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).
COMMUNICATIONS Communications Interface Port The Liebert GXT2U UPS has a standard DB-9 serial port female connector located on the rear of the UPS unit.
Pins 5 & 6 - Any-Mode Shutdown 1. Pin 6 of the 9-pin communication connector is used for “Any-Mode Shutdown” of the UPS output. This control input may be used in special applications to disable the UPS output power—both Inverter and Bypass. 2. The Options tab allows the behavior of the Any-Mode Shutdown feature to be modified. When the program opens, or the REFRESH button is pressed, the UPS setting is read by the configuration program and displayed.
UPS Intelligent Communications The Liebert GXT2U is equipped with a Liebert IntelliSlot® port to provide advanced communication and monitoring options. Liebert’s MultiLink software continually monitors the UPS and can shut down your computer or server in the event of an extended power failure. Liebert MultiLink can also be configured for use without the serial cable when the Liebert IntelliSlot SNMP/Web card is installed in the UPS.
CONFIGURATION PROGRAM This is a new feature included with the new Liebert GXT2U line. Several UPS settings that were previously not available or required custom manufacturing may now be modified using this program. For most users, the factory default settings will be adequate. This manual illustrates the features available for modification, as well as the factory default setting. NOTE The UPS must be turned off—and not powering connected equipment— before you make any changes to configuration settings.
MAINTENANCE The Liebert GXT2U requires very little maintenance. The batteries are valveregulated, nonspillable, 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 recommended to plug the UPS in for at least 24 hours every four to six months to ensure full recharge of the batteries.
