  • Page 10: Introduction And System Description

    The UPStation GXT2-6000RT208 has an interface port for communication between the UPS and a network server or other computer systems. This port provides detailed operating information includ- ing voltages, currents and alarm status to the host system when used in conjunction with Liebert’s MultiLink™ software. MultiLink software can also control UPS operation remotely.

  • Page 11: 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 util- ity line and keep the sensitive equipment protected.

  • Page 12: 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 GXT2-6000RT208 utilizes valve-regulated, nonspillable, flame retardant, lead acid batteries.

  • Page 13: Major Components

    AJOR OMPONENTS The GXT2-6000RT208 is composed of three major assemblies to provide easier handling, installation and versatility. Main Frame and Electronics This 4U 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. The UPS is shipped with a basic hardwire distribution box.

  • Page 14: Removable Power Distribution Box

    Major Components Removable Power Distribution Box The UPS is shipped with a basic hardwire power distribution pack installed.

  • Page 23: Initial Startup And Electrical Checks

    NITIAL TARTUP AND 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). Perform initial system checks first. If the UPS configuration needs to be modified for your application, then go to the next section to review use of the configuration program.

    L14-30P Plug-in Connections—Including the PD-001 Distribution Box WARNING Miswiring power to the input (L1-L2-N-G) or connecting to single phase voltages (L-N-G only) may damage the UPS. A qualified electrician should verify that the L14-30R is properly wired before attaching the UPS. If the configuration program has been used to set the L-N voltage at 100, 110 or 115, then the input phase angle is required to be 180 degrees.
