IMPORTANT SAFETY INSTRUCTIONS,

SAVE THESE INSTRUCTIONS

This symbol indicates that
dangerous voltage constituting
a risk of electrical shock is
present within the unit.

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:

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

 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.

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"

TECHNICAL DESCRIPTION

THE CONTINUOUS POWER COMPANY

he Digital Technology-Extreme Temperature

T

(DTR(ET) Series Continuous Power System
(CPS) is a revolutionary new concept in total power
protection and management. The DTR(ET) 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
DTR(ET) Series RS232 port, frequency settings and
operation, alarm signals, load switching, fan
operation, etc. can all be programmed to meet
specific application requirements.

The DTR(ET) Series in a true on-line, continuous
power UPS. In the tradition of Clary products, the
DTR(ET) 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 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.

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 until 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 DTR(ET) UPS software
program, you can actually view, on your monitor, the
event history of the power distribution system with
the
DTR(ET) Series unit as the central hub. More
sophisticated users may implement the optional
SNMP package to accomplish full Network Power
Management.
