Sensitive electronic equipment operates best from sinewave power. For ease of use, the Liebert GXT2-10000RT208 features a light-emitting diode (LED) display to indi- cate both load percentage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm Silence/Battery Test button, a Standby button, user configurable program and two levels of alarms when the unit is operating on battery.
Battery Charger The battery charger utilizes energy from the utility power and precisely regulates it to continuously float charge the batteries. The batteries are being charged whenever the Liebert GXT2-10000RT208 is plugged in, even when the UPS is not turned on.
(20°C to 25°C). Optional external battery cabinets are available to extend battery run times. Static Bypass The Liebert GXT2-10000RT208 provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction. Should the UPS have an overload, overtemperature or UPS failure condition, the UPS automatically transfers the connected load to bypass.
Major Components AJOR OMPONENTS The Liebert GXT2-10000RT208 is composed of three major assemblies to provide easier handling, installation and versatility. Main Frame and Electronics This 6U cabinet arrives without internal batteries to lighten the UPS for easier installation. Once the cabinet has been placed in its final floor or rack position, the internal batteries may be installed.
Major Components Input/Output Terminal Blocks and Optional Output Distribution The UPS is shipped with hardwire terminal blocks. For maximum flexibility, additional distribution options are available that provide the benefit of output receptacle convenience.

Installation and Configuration 4. Get eight (8) M4 screws and eight (8) M4 nuts from the M4 nuts screws hardware pack in this kit. Each nut has a locking, nylon insert that begins gripping the screw when it is halfway tight.
Installation and Configuration External Battery Cabinet Installation Optional Liebert external battery cabinets may be connected to the UPS to provide additional battery run time. External battery cabinets are designed to be placed on one side of the UPS or stacked beneath the UPS.
Installation and Configuration Connect Input/Output Power The UPS has hardwire terminal blocks for input and output electrical connections. Optional output distribution modules permit connecting additional loads to the UPS. These optional plug-and-play distribution modules offer different types and numbers of connection plugs. WARNING The UPS must be completely powered down before beginning to make these electrical connections.

Initial Startup and Electrical Checks NITIAL TARTUP AND LECTRICAL HECKS Initial Startup and the Configuration Program—The UPS ships with a default 120 VAC L-N setting. This is also the most robust setting in that it can operate with either input phase angle (120 or 180 degrees).
Initial Startup and Electrical Checks 18. Press the On button for one second. The bypass indicator will light for several seconds before the UPS On indicator turns on continuously. If the batteries are charged above 90% of capacity, automatic battery test will run for about 15 seconds. 19.

NOTE If an accessory communication card has been installed in the Liebert IntelliSlot port in the UPS, the option card must be removed while using the configuration program. Use the serial communication cable to connect COM1 or COM2 of the host computer to the DB-9 com- munication port on the rear of the UPS.
COM port. Liebert MultiLink typically restarts automatically whenever the computer restarts. • The Liebert IntelliSlot port in the UPS CANNOT be in use by an internal, optional communica- tion card in the UPS card slot. Remove the option card.
Configuration Program 8.5.4 On-Screen Reminders As pending changes are selected, on-screen messages will remind the user if the UPS may be On, or must be Off, for the setting to be pro- grammed once the Apply or OK button is pressed.
L-N voltages available. Select the voltage that matches the nominal utility in your location. Output Voltage Selection Notes For the Liebert GXT2 dual inverter models, this sets the L1-N and the L2-N nominal voltage. The L1-L2 voltage depends upon the phase angle of the input utility and is auto-detected when power is first applied.
Configuration Program 8.6.3 Frequency Selection The UPS is normally designed for 50Hz or 60Hz operation. The factory default corresponds to the model. All models are capable of being used as 50Hz or 60Hz systems. The UPS will Auto-sense the utility frequency when first plugged in and set the nominal frequency to match. Therefore, for all nor- mal use the Auto Sense button should be selected.
This version of the configuration program will accompany Liebert GXT2 UPS models that support new programming features accessible using the Options Tab. If Version 1.6 (or later) is used with an earlier Liebert GXT2 model (with an earlier UPS firmware version), the Any Mode Shutdown features cannot be changed.
The Liebert GXT2-10000RT208 automatically detects external battery cabinets when they are connected. Use the Battery Cabinets Number selection box to select non-Liebert battery cabinets when used with the UPS. 8.9.1 Low Battery Time Warning The UPS will estimate remaining operating time when on batteries. A low battery alarm is activated if the estimated time reaches the Low Battery Time.
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. After the alarm is silenced, the Liebert GXT2-10000RT208 will reactivate the alarm system to alert of additional problems. NOTE The LOW BATTERY and BYPASS reminder alarms CANNOT be silenced.
Should the battery fail this test, the red Fault indicator along with the A and C diagnostic indicators will illuminate and an alarm will sound (refer to 13.0 - Troubleshooting). The remote test feature functions with Liebert MultiLink 3 software and can remotely initiate the battery test. Fault Indicator (Red) The Fault indicator is illuminated if the UPS has detected a problem.
Modes of Operation 10.0 M ODES OF PERATION 10.1 Normal Mode Operation 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.
OMMUNICATIONS 11.1 Communications Interface Port The Liebert GXT2-10000RT208 UPS has a standard DB-9 serial port female connector located on the rear of the UPS unit. Several signals are provided on this port and are assigned as follows: Table 2 DB-9 pin assignment...
2. Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes form the serial port using Liebert’s contact closure cable. It cannot be used with just a contact closure unless the relay is used to switch a voltage source. A 5-12 VDC signal for 1.5 seconds or greater is required to signal a shutdown.
Communications 11.4 Remote Emergency Power Off The UPS is equipped with a Remote Emergency Power Off (REPO) connector. The user must supply a means of interfacing with the REPO circuit to allow disconnecting the UPS input feeder breaker to remove all sources of power to the UPS and connected equipment to comply with national and local wiring codes and regulations.
Failure to recharge the batteries peri- odically will permanently degrade battery capacity. The Liebert GXT2-10000RT208 is designed to allow the user to safely replace the internal batteries. Read the safety cautions before proceeding. Contact your local dealer or Liebert representative to obtain the appropriate replacement battery kit part number and pricing.
Maintenance 12.2 UPS Power Module Replacement CAUTION The UPS must be switched to manual bypass before personnel begin to replace the power module. NOTE During the procedure, the connected load will not be protected from power disturbances, such as spikes, sags and failure. To remove the UPS power module without shutting off power to the connected load: 1.

13.1 Auto-Learning Battery Run Times As batteries age, the estimated run times may become less accurate. The Liebert GXT2-10000RT208 is programmed to “learn” from a full battery discharge and modify the estimated run time for the measured battery capacity. This can improve accuracy and compensate for aging batteries or batter- ies that operate at different ambient temperatures.
