Introduction 1.0 INTRODUCTION Congratulations on your choice of the Liebert GXT3 uninterruptible power system (UPS). The Liebert GXT3 comes in nominal power ratings of 5000VA, 6000VA and 10,000VA. It is designed to provide conditioned power to microcomputers and other sensitive electronic equipment. When it is generated, alternating current is clean and stable.
System Description 2.0 SYSTEM DESCRIPTION Output Input Dynamic Bypass L1 N Rectifier /PFC DC-to-DC Converter TVSS & EMI/RFI Filters Inverter L1 N Battery Charger Battery G 2.1 G 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 mains line and keep the sensitive equipment protected. 2.
System Description 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 Liebert GXT3 utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery design life, operate the UPS in an ambient temperature of 15°C to 25°C (59°F to 77°F).
Major Components 3.0 MAJOR COMPONENTS The Liebert GXT3 is composed of three major assemblies to provide easier handling, installation and versatility. 3.1 Main Frame and Electronics The cabinet is shipped with internal batteries installed and a basic, hardwire distribution box attached and ready to install.

Major Components 3.2 Internal Battery Packs The UPS has two internal battery packs behind a battery access door on the front of the unit. Each internal battery pack is fitted with a connector to link to the UPS. Figure 3 Internal battery pack with connector Battery Handle GXT3 10,000 Battery Pack shown; 5000 and 6000VA battery packs have same features Battery Connector Front of Battery Pack 3.3 Removable Power Distribution Box The UPS arrives with a power distribution pack installed.
What’s Included 4.0 WHAT’S INCLUDED The Liebert GXT3 is shipped with the following items: • Terminal Block Communication terminals • Compact Disk with • Liebert MultiLinkt® • Configuration program • User manual (electronic version) • USB cable, one; 2m (6-1/2 ft.
Installation and Configuration 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 8.2 - Initial Startup and Electrical Checks. Visually inspect the UPS for freight damage. Report any damage to the carrier and your local dealer or Emerson® representative. ! CAUTION The UPS is heavy (see 12.0 - Specifications). Take proper precautions when lifting or moving it.
Installation and Configuration b. Pull the operation and display panel gently, rotate it 90 degrees clockwise and snap it back into position, as shown in Figure 8. Figure 8 Rotate the operation and display panel Operation and Display Panel Rotated Clockwise 90 Degrees c. Pull the logo on the front plastic bezel cover gently, rotate it 90 degrees clockwise and snap it back into position. The rotated front plastic bezel cover is shown in Figure 8. d.
Installation and Configuration The adjustable rack-mounting brackets (Part#: RMKIT18-32) feature retaining latches to prevent users from inadvertently sliding the UPS or battery cabinet out of the rack. To install the rack mount brackets: 1. Unpack two (2) rack-mounting bracket assemblies and mounting hardware from this kit. Bracket assemblies are interchangeable between left-hand or right-hand.
Installation and Configuration 6. If available, apply a bead of grease 25mm (1") long at four (4) places inside the bottom, curved tracks of the front members as shown below right. The grease will allow the equipment to slide into the bracket assemblies more easily. ! CAUTION Lifting equipment into the rack may be a two-person job, depending on the weight of the equipment. Emerson® recommends taking the internal batteries out of the UPS during rack installation.
Installation and Configuration Figure 9 External battery cabinets connected to 10,000VA Liebert GXT3 10,000VA Liebert GXT3 Cables connecting battery cabinets to 10,000VA Liebert GXT3 Battery Cabinets 1. Visually inspect the external battery cabinet for freight damage. Report damage to the carrier and your local dealer or Emerson® representative. 2. For slide rail installations, first remove the top/side fin. Top/side fin slides forward and then lift up to remove.
Installation and Configuration 5.3 Connect Input/Output Power Figure 10 Power Distribution box removal—captive screws and maintenance bypass breaker Extract these captive screws Maintenance Bypass Breaker The UPS should arrive with the power distribution box attached. If the box needs to be removed for maintenance or replacement, follow these instructions to remove and install the power distribution pack. To remove: 1. Ensure maintenance bypass lamp is on.
Installation and Configuration 5.3.1 Distribution Box Electrical Connections Electrical connections are made through a removable power distribution box that attaches to the rear of the UPS. • PD2-CE6HDWRMBS fits the 5000 and 6000VA models of the Liebert GXT3 • PD2-CE10HDWRMBS fits the 10,000VA model of the Liebert GXT3 The installer must provide an upstream branch circuit breaker.
Installation and Configuration Figure 12 Terminal block connections—PD2-CE6HDWRMBS and PD2-CE10HDWRMBS PD2-CE6HDWRMBS L N L OUTPUT INPUT PD2-CE10HDWRMBS N L N INPUT L N OUTPUT NOTE The installer must provide circuit breaker protection according to local codes. The mains disconnect should be within sight of the UPS or have an appropriate lock-out. Maintain service space around the UPS or use flexible conduit.
Configuration Program 6.0 CONFIGURATION PROGRAM The final step of installation may require custom configuration of your UPS using the enclosed configuration program. Some configuration settings may be changed only while the UPS is off. These should be set before the UPS is put into full-time service powering the critical load. For most users operating with 230VAC and with no external batteries, the factory default settings will be adequate. 6.

NOTE The Liebert GXT3’s battery has been fully charged before delivery, but some charge will be lost during storage and shipping. To ensure that the battery has adequate reserve power to protect the connected load, charge the battery for three hours before putting the UPS into service. 8.
Operation 8.3 Manual Battery Test To initiate a manual battery test, press the On/Alarm Silence/Manual Battery Test button for at least half a second while operating from mains power with no alarm conditions present. • If only the first two of the five LED segments illuminate, allow the UPS to recharge the batteries for 24 hours. • Retest the batteries after 24 hours of charging.
Operation 8.8 IT Power System Configuration 1. Remove screws on the IT Power System Access Cover as shown in Figure 15. 2. Disconnect the connectors as shown in figure. 3. Install IT Power System Access Cover and screws.
Communication 9.0 COMMUNICATION 9.1 Communication Interface Port The Liebert GXT3 UPS has a terminal block on the rear of the UPS unit. Several signals are provided on this port and are assigned as follows. 9.2 Terminal Block Communication The terminal block includes eight pins, as shown in Figure 16. Figure 16 Terminal block communication terminals 9.2.
Communication 9.2.2 Battery Mode Shutdown Battery Mode Shutdown permits shutting down the UPS by turning off the rectifier, inverter and static switch so that there is no power to the load when the UPS is On Battery. The auxiliary power for the UPS will still be active. Battery Mode Shutdown can be performed locally or remotely: • Local Battery Mode shutdown can be performed by shorting the pins in Set 4.
Communication 9.3.1 Liebert MultiLink® Liebert MultiLink 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 USB cable when the Liebert IntelliSlot® SNMP/Web card is installed in the UPS. Additionally, Liebert MultiLink can be configured to coordinate shutdown across the network with other computers running Liebert MultiLink when you purchase a Liebert MultiLink License Kit.
