IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE
INSTRUCTIONS
This manual contains important instructions that
should be closely followed during installation and
maintenance of this UPStation GXT 6kVA
Maintenance Bypass.
This product is designed for commercial / industrial
use only. This product is not intended for use with
life support and other designated “critical” devices.
Maximum load must not exceed that shown on the
Maintenance Bypass Cabinet rating label.
The UPStation GXT 6 kVA Maintenance Bypass is
designed for use on properly grounded (earthed)
208/240VAC 60Hz supply, for installation by
qualified personnel. This UPS equipment is
intended to be installed by a qualified / certified
electrician who must review and approve customer
supplied wiring, circuit breakers, intended loads
and verify correct input, output and grounded
(earth) connections to ensure compliance with
technical standards and national and local
electrical codes. Installation instructions and
warning notices are in the Cable Installation
section of this manual beginning on page 6.
Install the bypass equipment in a clean
environment, free of conductive contaminants,
moisture, flammable liquids, gases, and corrosive
substances.
!WARNING
LETHAL VOLTAGES MAY BE
PRESENT WITHIN THIS UNIT

NOT OPERATING. OBSERVE ALL
CAUTIONS AND WARNINGS IN
THIS MANUAL. FAILURE TO DO
SO MAY RESULT IN SERIOUS
INJURY OR DEATH. NEVER
WORK ALONE.

GENERAL DESCRIPTION
Congratulations on your purchase of Liebert's
UPStation GXT 6 kVA Maintenance Bypass. As
with every Liebert product, we stand behind our
quality. If you have any questions concerning this
Maintenance Bypass, please feel free to contact
your local sales representative, or call the
appropriate Technical Support number listed on
the back of this manual.
To ensure proper installation and operation of this
unit, please read this manual thoroughly.
While installation must be completed by a
qualified / certified electrician, general operation
may be performed without special training.
SYSTEM DESCRIPTION
The Liebert UPStation GXT 6 kVA Maintenance
Bypass is intended for use with the UPStation GXT
6 kVA UPS. Typical applications include
supporting workstations, servers, network, telecom
or other sensitive electronic equipment.
The UPStation GXT 6 kVA Maintenance Bypass
was designed to provide maximum system
availability to business-critical equipment. The
bypass allows for transfer of connected loads to an
alternate power path, allowing full isolation of the
UPS. After connected loads are switched to
alternate power and the UPS is isolated, the UPS
can be turned off and removed from service with
no interruption of power to connected loads.
The Configurable Output Distribution was
designed to provide maximum flexibility to
business-critical equipment.
Various output receptacle options are available
from 15 A to 30 A. Hardwire options are also
available with a branch rated circuit breaker.
Features
• Supports up to 30A loads
• Compact design
• Highly configurable
• Multiple power path indicators
• High-speed, break-before-make transfer
switch
Standard Components
• Provisions for hardwire output
• Power indicator lamps
• Branch rated circuit breakers
• Easily accessible terminal blocks
Options
• Field-installable output distribution kits
NOTE
The 120V loads need to be balanced on
the UPS output. To do this, when
connecting 120V equipment to the
Maintenance Bypass (MB), start at one
end of the MB and fill in toward the
other end.

CABLE INSTALLATION
WIRING PREPARATION
For access to terminal blocks, see diagrams on
page 4.
POWER CABLE INSTALLATION
Refer to the chart below when selecting cables:
!CAUTION
Please read this section
thoroughly before attempting to
install wiring to this unit.
Be sure that the unit is not
connected to any AC mains power
source or UPS before installing
any wiring to this unit. This should
be installed by a qualified/certified
electrician.
NOTE
The 120V loads need to be balanced on
the UPS output. To do this, when
connecting 120V equipment to the
Maintenance Bypass, start at one end of
the output modules and fill in toward the
other end. Load balancing must be
performed with the UPStation
GXT6000T - 208X and 240X. It is not
required on the GXT6000T-208 because
the unit has no 120V output.
