INTRODUCTION
THE CONTINUOUS POWER COMPANY
ongratulations! You have selected the
highest quality protection for your continuous
C
power needs. This unit offers a quiet and
compact package with superior performance
you can depend on. You now own a GT Series
Continuous Power System (CPS) which is an all
Digital Technology product manufactured by Clary
Corporation, the first name in uninterruptible power
system (UPS) reliability. The GT designation
denotes a custom configuration offshoot from the
standard DT Series. This means the addition of a
step-up or step-down voltage conversion
transformer for global applications. The Continuous
Power System is the highest order in the hierarchy
of UPS products. When power problems occur,
there can be no compromising the reliability of your
power solution. The GT Series Continuous Power
System is your complete
power solution.
IMPORTANT SAFETY INSTRUCTIONS,
SAVE THESE INSTRUCTIONS
This Users Manual is provided with your new GT
Series unit. It will enhance your understanding of
the product and its functions. Read this handbook
carefully in the order it is presented prior to
operating your unit. This will save you time and
effort in your installation and application. The
illustrations will also familiarize you with this unit’s
operating modes and indications. Always operate
the unit within the guidelines and specifications
given to maximize the unit's efficiency and lifetime.
Also, your understanding of the product is essential
in providing you years of service for your continuous
power requirements.
This unit has been manufactured and tested to meet
specific safety standards. It meets UL and FCC
requirements and complies with safety performance
standards.
This symbol indicates that
dangerous voltage constituting
a risk of electrical shock is
present within the unit.
This symbol indicates that there
are important operating and
maintenance instructions in the
!
literature accompanying this
unit.
CAUTION
RISK OF ELECTRIC
SHOCK DO NOT OPEN
!
This manual contains important safety instructions that should be followed during installation and maintenance of
the UPS and batteries. Be aware of the following symbols and their meaning as they appear throughout the
manual:
This equipment generates and uses radio frequency energy and if not
installed and used properly in strict accordance with the manufacturer's
instructions, may cause interference to radio and television reception. All
units in this manual have been tested and found to comply with the limits
for a Class A computing device in accordance with the specifications in
Subpart J of Part 15 of FCC Rules, which are designed to provide
reasonable protection against such interference in a commercial
installation. However, there is no
in a particular installation. If this equipment does cause interference to
radio and television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
guarantee that interference will not occur
If necessary, the user should consult the dealer or an experienced
radio/television technician for additional suggestions. The user may find
the following booklet prepared by the Federal Communications
Commission helpful:
"How To Identify and Resolve Radio-TV Interference Problems"
This booklet is available from the U.S. Government Printing Office,
Washington, DC 20402, Stock No. 004000003454.
Reorient the receiving antenna.
Relocate the UPS wi th respect to the receiver.
Move the UPS away from the receiver.
Plug the UPS into a different outlet so that the UPS
and receiver are on different branch circuits.

TECHNICAL DESCRIPTION
THE CONTINUOUS POWER COMPANY
he Digital Technology (GT) Series Continuous
Power System (CPS) is a revolutionary new
concept in total power protection and
T
management. The GT Series is a
microprocessor-based UPS that now allows the user
to set most of the control feature parameters. By
directly linking a personal computer to the GT Series
RS232 port, frequency settings and operation, alarm
signals, load switching, fan operation, etc. can all be
programmed to meet specific application
requirements.
The GT Series is a true on-line, continuous power
UPS. In the tradition of Clary products, the GT
Series generates the same high quality and proven
reliability to provide the best power protection
available for today’s critical applications.
In keeping with state-of-the-art design, the power
electronics are completely governed by an on-board
microprocessor. Given the powerful memory
capability of today’s microcontrollers, this
microprocessor has evolved the UPS into an all-inone complete power distribution and monitoring
center. Not only is your critical load insured of the
most reliable and constant power available, but the
user may now continuously track status of the
supply components that keep the entire system
operational. Production downtime can now be
virtually eliminated by knowing exactly what patterns
the supply utility power maintains and by knowing
exactly the condition and life expectancy of the
battery reserve.
Reference the block diagram for a simplified
explanation of the system’s operation. The AC utility
source is connected to the power and microelectronics when the input switch is closed. The
input line is filtered, power factor corrected and
rectified for enhanced performance without
disturbing other equipment that may share the same
utility circuit. In GT units, a step-down, input
isolation transformer is added to accept a wide
range of input voltages for global applications.
Output transformers, SNMP adapters and many
other options are available.
The microprocessor controls an Inverter Generator
that produces a low harmonic, AC sinewave for
continuous power applications.
When the input AC utility line fails, the battery circuit
within this system takes over to ensure continuous
power. Only after properly rated power is returned,
does the microprocessor reconnect the input source
back into the system.
The microprocessor is directly tied to an external
RS232 connector port. This allows the user to
monitor and even set some of the operating
parameters. With a simple link to a personal
computer using the DT-UPS2 software program, you
can actually view, on your monitor, the event history
of the power distribution system with the GT Series
unit as the central hub. More sophisticated users
may implement the optional SNMP package to
accomplish full Network Power Management.

PACKAGING
our UPS has been carefully packaged to
withstand most abuse sustained during
shipment. The packing material has been
Y
specifically designed to protect this system for
normal handling, using most shipping carriers. If
there is significant damage to the carton, or if there
is any physical damage to this unit, report this to
your carrier.
These units are encapsulated in a protective wrap
that comes apart once the product is removed from
the shipping carton. Save all packing material for
future use.
Take extra precaution when removing or returning it
to the box. Because this unit contains a battery, it
can be quite heavy. Never attempt to unpackage
the equipment unassisted.
The packaging also contains important information
!
on use and care as well as valuable warranty
information. Read all materials before storing this
literature with your other valuable product
documents.
