Introduction 4 2.0 I NTRODUCTION Congratulations on your choice of the Liebert GXT2U™ Uninterrupt- ible Power System (UPS). It provides con ditioned po wer to microcom- puters and other sensitive electronic equipment. Upon generation, AC power is clea n and stable.
Major Components 5 3.0 M AJOR C OMPONENT S 3.1 T RANSIEN T V OLT AGE S UR GE S UPPRESSION (TVSS) AND EMI/RFI F ILTERS These UPS components provide surge protection and filter both elec- tromagnetic interference (EMI) an d radio frequency interference (RFI).
Major Components 6 3.4 B ATTERY C HARGER The battery charger uti lizes energy from the utility po wer and pre- cisely regulates it to contin uously “float charge” the batteries. The bat- teries are being charged whenev er the Liebert GXT2U is plugge d in, even when the UPS is not turned on.
Major Components 7 3.8 L IEBERT GXT2U, R EAR V IEW Rev . USBCARD Input Fuse / Circuit Breaker AC Input Support Base Output Receptacles External Battery Connector Cooling Fa n USB card be ing fitted in.
Installation 8 4.0 I NST ALLATION 4.1 P REP ARATION 1. Visually inspect the UPS for fr eight damage. Report damage to the carrier and your local deal er or Liebert representative. 2. Decide where to place the Lieber t GXT2U. Install the UPS indoors in a controlled environment, wh ere it cannot be accidentally turned off.
Installation 9 4.3 R ACK -M OU NT UPS C ONVERSION AND I NSTALLATION 1. For slide rail install ations, first remove the top/side fin. Slide the top/side fin forward, then lift it up to remove. If d esired, install the optional rack mount handles th at were shipped wi th the UPS.
Installation 10 3. Determine the height position inside the rack enclosure where you want to mount the UP S or battery cabinet. Install rear member of each bracket assembly into rack enclosure with two (2) M5 screws provided in this kit. (See figure at right.
Installation 11 5. Prepare the UPS or battery cabinet (the “equipment”) for rack mounting by following instructions in the equipment’s user manual. The equipment may require addi tional parts to be added or pa rts to be removed for rack mounting.
Installation 12 8. Secure front of the equipment to rack mounting rails to prevent the equipment from sliding out of position. If secu ring holes are provided on front of the equipment that align with the center holes on return flange of front members, you can use the four (4) extra M5 screws provided in this kit to secure the equipment.
Installation 13 4.4 E XTERNAL B ATTERY C ABIN ET I NST ALLATION Optional Liebert external batt ery cabinets may be connected to the UPS to provide additional battery run ti me. External battery cabinets are designed to be placed all on one si de of the UPS or stacked beneath the UPS.

Controls and In dicators 16 5.8 AC I NPUT I N DICATOR L ED (G REEN ) The AC Input indicator LED is il luminated when utilit y power is available and within the inpu t specifications.
Operating Instructions 17 6.0 O PERATING I NSTRUCTIONS 6.1 N ORMAL M ODE O PERATION 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.
Operating Instructions 18 6.3 B ATTERY M ODE O PERATION Battery mode occurs in event of an extreme input voltage condition or com- plete utility fail ure. The battery system supplies power through the DC to DC converter to the inverter to generate power for the connected load.
Communications 19 7.0 C OMMUNICATIONS 7.1 C OMMUNICATIONS I NTERFA CE P ORT The Liebert GXT2U UPS has a standard DB-9 serial port female con- nector located on the rear of th e UPS unit. Several s ignals are pro- vided on this port and are assigned as fo llows: * Maximum voltage and current on pins 1, 7, 8, and 9 is 60 VDC ; 10.
Communications 20 7.2 P INS 4 & 5 - R EMOTE S HU T DOWN ON B ATTERY 1. This pin is functional only when th e UPS is in battery m ode. If the UPS is bein g powered by the utility , Pin 4 will i gnore any sig nal on this pin. 2. Pin 4 requires a 5- 12 VDC signal to shutdown.
Communications 21 7.3 P INS 5 & 6 - A NY -M ODE S HU T DOWN 1. Pin 6 of the 9-pin communication connector is used for “Any-Mode Shutdown” of the UPS output. This con trol input may be used in special applications to disable the UPS output power—both Inverter and Bypass.
Communications 22 7.4 UPS I NTELLIGENT C OMMUNI CATIONS The Liebert GXT2U is equipped with a Liebert IntelliSlot ® port to pro- vide advanced communica tion 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.
Configuratio n Program 23 8.0 C ONFIGURATION P ROGRAM The configuratio n program inclu ded with the Liebert GXT2U line allows modification of several UPS settings tha t were previously unavailable or required custom manufacturing.
Mainten ance 24 9.0 M AINTENANCE The Liebert GXT2U requires very little maintenance. The batteries are valve-regu lated, nons pillable , lead acid an d should be kept charged to obtain th eir designed life. The UPS con tinuously charg es the batteries when connected to the utility supply .
Mainten ance 25 9.1.1 Internal Battery Replacement Proc edures 1. Gently remove the front plastic bezel cover from the UPS. 2. Loosen and remove the four scre ws on the front battery door. Lay the battery door as ide for reassembly. Note: The 3000VA model includes a pull handle to remove this door.
Mainten ance 26 9.2 F USE R EPL ACEMENT 1. Remove the input fuse. 2. Locate the spare input fuse that is included with the UPS. 3. Insert the spare fuse into the fuse holder, and reinstall assembly into the UPS. Twist by hand; rotate clockwise unti l fuse holder locks into position .
Troubleshooting 27 10.0 T ROUB LESHOOTING The information below indicates various symptoms a user may encounter in t he event the Liebert GXT2U develops a prob lem. Use this information to determin e whet her external factors caused the problem and how to re medy the situation.
Troubleshooting 28 Under fault conditi ons, the Fault indi cators will be il luminated indefi- nitely while battery charger is operational, or for a maximum of 5 min- utes while ba ttery charger is not oper ational.
