INTRODUCTION
THE CONTINUOUS POWER COMPANY
ongratulations! You have selected the highest
quality protection for your continuous power
C
needs. This unit offers a quiet and compact
package with superior performance you can
depend on. You now own a CT 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 CT 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. 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 CT Series Continuous Power System is
your complete
power solution.
IMPORTANT SAFETY INSTRUCTIONS,
SAVE THESE INSTRUCTIONS
This symbol indicates that
dangerous voltage constituting
a risk of electrical shock is
present within the unit.
!
This Users Manual is provided with your new CT
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 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
guarantee that interference will not occur 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:
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 with 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 (DT) Series Continuous
Power System (CPS) is a revolutionary new
concept in total power protection and
T
management. This UPS is a microprocessorbased unit that now allows the user to set most of the
control feature parameters. By directly linking a
personal computer to the CT Series RS232 port,
frequency settings and operation, alarm signals, load
switching, fan operation, etc. can all be programmed to
meet specific application requirements.
The CT Series is a true on-line, continuous power
UPS. In the tradition of Clary products, the CT 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-in-one 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, on the following page,
for a simplified explanation of the system’s operation.
The AC utility source is connected to the power and
micro-electronics 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 CT units, a step-down, input isolation transformer is
added to accept higher input voltages for custom
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 supplied, you can actually
view, on your monitor, the event history of the power
distribution system with the CT Series unit as the
central hub. More sophisticated users may implement
the optional SNMP package to accomplish full Network
Power Management.

PACKAGING
our CPS 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.
