Patented Feature Enhances Reliability
The Liebert GXT2 6 kVA includes a patented output neutral
bonding feature designed to comply with UL 1778, which
requires that input conductors of the UPS (including
neutral) be disconnected from the input source when the
UPS is in battery mode. The Liebert GXT2 6 kVA features a
patented circuit that maintains the UPS output neutral to
ground bond in all modes of operation, thereby eliminating
any voltage induced on the UPS output neutral connection.
Flexibility :
■ Rack/tower configuration —
A single part number installs
in either configuration.
■ Automatic frequency detection —
The Liebert GXT2 6 kVA detects
and matches line input frequencies
of either 60 or 50 Hz.
■ Additional runtime with 2U
battery cabinets — UPS cabinet
includes rear panel plug-and-play
connections for optional additional
battery cabinets.
■ IntelliSlot ™ communications port —
Utilizes Liebert IntelliSlot Web
Card to provide SNMP and web-based
monitoring and control your UPS.
■ Includes Windows-based
configuration program — Allows
various operating parameters to be
adjusted and tests to be scheduled.
■ Built-in serial communications
for use with Liebert MultiLink
™
Automated Shutdown
Software — Allows you to monitor
communication between the
UPS and a server, and ensures
a graceful unattended shutdown.
■ Built-in closure signals — Provides
notification to monitoring systems
of operating conditions including:
on battery, low battery, battery mode
shutdown and any mode shutdown.
■ Emergency Power Off (EPO) —
Terminal connections for a normally
open or normally closed emergency
power off switch.
Other Product Features Of The New Liebert GXT2 6 kVA Include:
Reliability
■ Wider Input Voltage Window
Minimizes Battery Use — The
Liebert GXT2 6 kVA features a
wide input voltage window that
allows the UPS to support the
critical load without having to
transfer to battery, extending
system availability for when
battery back-up is truly needed.
■ Internal automatic and manual
bypass — Assures continuity of
power to critical loads during
system maintenance or in case
of internal fault.
■ Self-diagnostics — Automatically
tests unit electronics and batteries.
Designed to simplify maintenance
and troubleshooting.
■ User-replaceable hot-swappable
internal batteries — Provide five
minutes of runtime at full load.
Low Total Cost Of Ownership
■ Standard two-year warranty
■ Uses less rack space leaving more
room for network equipment.
■ Batteries are shielded from heat
generating electronic components,
enhancing battery life.
■ Battery cutoff voltage
automatically adjusts based
on load, extending battery life
by preventing over-discharge
of batteries.
