Introduction 4 2.0 I NTRODUCTION Congratulations on your choice of the Liebert UPStation GXT 2U™ Uninterruptib le Power Sy stem (UPS). It provi des conditione d power to microcomputers and other se nsitive electron ic equipm ent. Upon generation, AC power is clea n and stabl e.
Major Components 5 3.0 M AJOR C OMPONENT S 3.1 T RANS IENT V OLTAGE S URGE S UPPRESSION (TVSS) AND EMI/RFI F ILTERS These UPS components provide surge protectio n and filter both elec- tromagnetic interference (EMI) and radio frequency interference (RFI).
Major Components 6 3.4 B ATTERY C HARGER The battery charger ut ilizes energy from the util ity power and pre- cisely regulates it to contin uously “float charge” the batteries. The bat- teries are being charged whenever the UPSta tion GXT 2U is plugged in, even when the UPS is not turned on.
Major Components 7 3.8 GXT 2U (R EAR V IEW ) Input Fuse / Circuit Breaker AC Input Support Base Output Receptacles External Battery Connector Cooling F an Intellislot ® Port DB-9 Communicat ions Port.
Installation 8 4.0 I NST ALLATION 4.1 P REP A RATION 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 GXT 2U. Install the UPS indo ors in a controlled environment, where it ca nnot be accidentally turned off.
Installation 9 4.3 R ACK -M OUNT UPS C ONVERS ION AND I NSTALLATION 1. For slide rail installations, first remove the top/side fin. Slide the top/side fin forward, then lift it up to remove. I f desired, install the optional rack mount handles th at were shipped wi th the UPS.
Installation 10 3. Determine the height positio n in side 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 o r 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 positi on. If secu ring holes are provided on front of the equipm ent that align with the center holes on return flange of front member s, you can use the four (4) extra M5 screws provided in this kit to secure the equipment.
Installation 13 4.4 E XTERNAL B AT TERY C ABINET I NSTALL ATION Optional Liebert external battery 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.

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 failure. 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 NTERFACE P ORT The UPStation GXT 2U UPS has a standard DB-9 serial port female connector located on the rear of the UPS unit. Several signals are pro- vided on th is port and are assigned as follows: * 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 HUTDOWN ON B ATT ERY 1. This pin is function al only when the UPS is in battery mode. If the UPS is bein g powered by the utility , Pin 4 will ignore any signal 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 OD E S HUTDOWN 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 outpu t power—both Inverter and Bypass.
Communications 22 7.4 UPS I NTELLIGENT C OMMUNI CATIONS The UPStation GXT 2U is equipped with an Intelli slot ® port to pro- vide advanced communication and monitoring options. Liebert’s MultiLink software cont inually monitors the UPS and can shut down your computer or server in the event of an extended power failure.
Configur ation Program 23 8.0 C ONFIGURATION P ROGRAM The configuratio n program inclu ded with the UPStation GXT 2U line allows modification of several UPS settings that were previousl y unavailable or required custom manufacturing.
Mainten ance 24 9.0 M AINTENANCE The UPStation GXT 2U requires ve ry little maintenance. The batter- ies are valve-regulated, nonspillable, fl ame retardant, lead acid, and should be ke pt cha rged to obt ain their designed life. The UPS cont inu- ously charges the batteries when connected to the utility supply.
Mainten ance 25 9.1.1 Internal Battery Replacement Procedures 1. Gently remove the front plas tic bezel cover from the UPS. 2. Loosen and remove the four scre ws on the front batt ery door. Lay the battery door as ide for reassembly. Note: The 3000VA model incl udes a pull handle to remove this door.
Mainten ance 26 9.2 F USE R EPLACEME NT 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 rein stall assembly into the UP S. Twist by hand; rotate clockwise until fu se holder locks into position.
Trou bleshooting 27 10.0 T ROUBLESHO OTING The informatio n below indi cates various symptoms a user may encounter in the event the UPStation GXT 2U develops a problem. Use this information to determine wh ether external factors caused the problem and how to re medy the situation.
Trou bleshooting 28 Under fault conditions, the Fault indi cators will be il luminated indefi- nitely while battery charger is oper ational, or for a maximum of 5 min- utes while ba ttery charger is not oper ational.
