Page 7: Introduction
The UPStation GXT2 has an interface port for communication between the UPS and a network server or other computer systems. This port provides detailed operating information including voltages, cur- rents, and alarm status to the host system when used in conjunction with Liebert MultiLink™ soft- ware. MultiLink software can also remotely control UPS operation. -
Page 8: System Description
YSTEM ESCRIPTION Input TVSS & EMI/RFI Filters 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. -
Page 9: Dc-To-Dc Converter
DC-to-DC Converter The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the opti- mum operating voltage for the inverter. This allows the inverter to operate continuously at its opti- mum efficiency and voltage, thus increasing reliability. Battery The UPStation GXT2 utilizes valve-regulated, nonspillable, lead acid batteries. -

Inspect all wiring, cables, and connection. 4. If external battery cabinets are used, verify that the battery interconnect cables are fully inserted in the sockets. -
Page 21: Configuration Program
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. GXT2-6000RT230 and GXT2-4500RT230 Configuration Program Features • Select one of three L-N output voltages to match local voltages. • Enable/Disable Auto-Restart. -
Page 22: Controls And Indicators
• After 24 hours, retest the batteries. • After the batteries have been retested, if only three of the five Battery LEDs illuminate, contact your local dealer, Liebert representative or Liebert Worldwide Support Group. Standby/Manual Bypass Button This button controls output power to connected load(s) and has dual functions: Standby and Manual Bypass. -
Page 23: Load Level Indicators (4 Green, 1 Amber)
Load Level Indicators (4 Green, 1 Amber) The load level indicators display the approximate electrical load placed upon the UPS at all times. Battery Level Indicators (5 Green) The battery level indicators display approximate battery capacity at all times. The UPStation GXT2 is equipped with automatic and remote battery test features. The automatic test occurs every 14 days (this option is user configurable) if mains has not been interrupted. -
Page 24: Operating Instructions
PERATING NSTRUCTIONS Normal Mode Operation During normal operation, mains 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. -
Page 25: Communications
2. 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. -
Page 26: Ups Intelligent Communications
When the DB9 OCWEBCARD serial port cable is removed, the OCWEBCARD DB9 connector needs to be covered. The DB9 cover is included with the UPS. Liebert's MultiLink software continually monitors the UPS and can shut down your computer or server in the event of an extended power failure. -
Page 27: Remote Emergency Power Off
10.4 Remote Emergency Power Off The UPS is equipped with a Remote Emergency Power Off (REPO) connector.
