5.0 – OVERVIEW
General
The ETA SYSTEMS series of Uninterruptible Power Managers are the most advanced, line-interactive, true
sinewave UPM products available for your application. Each model is designed to provide total protection
for your system from a complete range of power quality problems. ETA UPM solutions will protect your
installation from normal mode voltage impulses, electrical noise, sags and surges, protracted brownouts,
and complete blackouts. And because each UPM contains an isolation transformer, it completely eliminates
common mode (neutral to ground) voltages that are a constant threat to the reliable operation of
microprocessor based systems. When AC power is present, the UPM constantly filters and conditions the
power supply. When AC power fails, the UPM uses its internal, maintenance-free battery to supply reserve
power to your computer system. Regardless of whether or not commercial power is present, the UPM is
constantly on the job, ensuring a fully conditioned, safely managed interface between your computer system
and its electrical power supply. Figure 1 illustrates the basic operation of the UPM.
Sinewave Output
The output voltage of all ETA UPM models is a true, low distortion sinewave – the kind that the utility
company provides to the wall outlet and the kind that your equipment is designed to work with. This
provides guaranteed compatibility even with the most sensitive electronic loads.
Voltage Manager™
The voltage of the AC power source can often fluctuate from its nominal rating. These deviations in line
voltage are tolerated quite well by most switch mode power supplies (the type used in many modern
electronic systems). However, some UPS products may misinterpret these transient changes in line voltage
as a power outage and erroneous battery operation may occur. This type of activity results in unnecessary
strain on the battery and may eventually shorten its life. ETA SYSTEMS’s UPM products feature Voltage
Manager – a circuit that constantly monitors the AC power source. If minor changes in AC voltage occur,
Voltage Manager adjusts the input voltage to the UPM circuitry so that erroneous inverter operations are
avoided. Ensuring that the UPM switches to its batteries only in the event of a true power outage results in
longer battery life and a lower cost for both maintenance and ownership.
Start Manager™
Start Manager is special circuitry that allows you to start the UPM from either the main AC supply or from its
own internal battery. On occasion, AC power may not be available – such as when installing a system in a
location where the electrical wiring has not been completed. Start Manager allows you to start the UPM and
its connected system to perform final tests on both the UPM and the computer systems it’s powering.

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER

Communications Manager™
Many uninterruptible power systems provide only a basic software interface with the computer system they
protect. Communications Manager combines the signaling capabilities of the rear panel communication port
with the management capabilities of ETA SYSTEMS’s communication software suite. Using your
computer’s monitor, Communications Manager conveniently displays input and output voltage, output
current, power line frequency, battery voltage, load percentage, and temperature. Communications
Manager even initiates user defined automatic system shutdowns during extended power outages.
Communications Manager allows a system operator to locally or remotely control the shutdown and startup
of equipment connected to the UPM and provides this control either directly or through the operation of a
customized schedule that can be developed to meet specific operating requirements.
Configuration Manager™
Configuration Manager allows the user to control certain parameters of the UPM such as operating voltage.
With Configuration Manager, for example, operating voltage of North American units can be set for 120 volts
in the United States or 100 volts for Japanese installations. Some of Configuration Manager’s features are
accessed through Communications Manager – such as those that allow adjustment to the voltage transfer
points of the UPM inverter. With Configuration Manager you can even program output receptacles to turn
off themselves and their connected loads at pre-determined times following a power outage.
User Replaceable Battery
Eventually every UPM requires a new battery. ETA SYSTEMS expects the battery in your to last a minimum
of two years – perhaps longer if power outages are short and infrequent. ETA makes battery replacement
by the user easy and fast. And it’s not necessary to turn off the UPM or the connected system. The battery
may be “hot-swapped” while the system is running.
6.0 – OPERATION
On/Off Button
The On/Off button is a dual function control:
When the UPM is off and AC power is present to the UPM input, pressing the On/Off button for more
than 3 seconds will turn the UPM on. If Start Manager’s rear panel switch is enabled, pressing the
On/Off switch for 3 seconds or more will “cold-start” the UPM on its internal battery.
When the UPM is on, pressing the On/Off button for more than 3 seconds will turn off the UPM and
output power.

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER
7
Test/Silence Button
The Test/Silence button is a dual function control:
Pressing the Test/Silence button when AC power is present and the UPM is operating causes the UPM
to enter a self test mode in which it tests both battery and inverter for a few seconds before returning to
the AC supply. We recommend you close all open files before initiating self-test.
When AC power fails, the UPM warns you with an audible alarm. The Test/Silence button is used to
silence the alarm. When battery power begins to run low, the audible alarm will automatically return
and beep at a faster rate.
Load Monitor
The Load Monitor is a 5-segment LED display that shows the current load percentage. The first four LEDs
each indicate approximately 20% load. When illuminated, the final LED indicates that your connected
equipment is consuming 110% of the UPM rated capacity.
Battery Charge Monitor
The Battery Charge Monitor is a 5-segment LED display that shows the charge capacity of the internal
battery from zero to 100%. Each LED indicates approximately 20% of full charge.
Status Monitor
The status monitor is a row of six individual LEDs that each indicate the status of a part of your UPM
system. The first three LED’s work with ’s Voltage Manager. All six LED’s are explained in the following
table.
LED 1 Voltage Manager Boost Mode: When this LED is illuminated, Voltage Manager has detected that
a low voltage condition exists, and it is compensating by increasing voltage to the UPM input to
the correct level.
LED 2 Voltage Manager Normal Mode: Voltage Manager has determined that input line voltage is
normal and within parameters. No adjustment is necessary.
LED 3 Voltage Manager Buck Mode: When this LED is illuminated, Voltage Manager has detected that
an overvoltage condition exists, and it is compensating by reducing voltage to the UPM input to
the correct level.
LED 4 Battery Mode: When this LED is illuminated, either commercial AC power has been lost or the
UPM has been put into self-test using the Test/Silence button. In Battery Mode, the UPM is
operating on its internal batteries. This LED will remain illuminated until the self-test is completed

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER
8
or until commercial AC power returns.
LED 5 Battery Weak: When this LED is illuminated, the battery requires either recharging or
replacement. If the LED remains illuminated after a 12-hour charge period, the internal battery
should be replaced.
LED 6 Overload: When this LED is illuminated, the UPM is overloaded. Remove load from the UPM by
determining, which of the connected pieces of equipment is the least critical, and disconnect it
from the UPM. Operating the UPM in an overloaded condition, may cause the UPM to protect
itself by shutting down and removing power unexpectedly to all connected components.
Configuration Manager Receptacle Indicators
The four clustered LEDs in the center of the front panel indicate the output receptacle status as controlled by
Configuration Manager. Configuration Manager addresses receptacle control differently for some of the
models (See following explanation).
350 VA models: Configuration Manager treats receptacles 1and 2 as a group (Bank 1) and receptacles
3 and 4 as a group (Bank 2). For these models, LED 1 and 2 (Bank 1) will either be on together or off
together. LEDs 3 and 4 (Bank 2) will also be on or off together. It is not possible to control receptacles
1 and 2 or receptacles 3 and 4 separately. It is only possible to separately control Bank 1 and Bank 2.
500 and 800 VA models: The top two receptacles are Bank 1 and the bottom four receptacles are Bank
2. On these models, LED 1 and 2 (Bank 1) will either be on together or off together. LEDs 3 and 4
(Bank 2) will also be on or off together. It is not possible to control receptacles 1 and 2 or receptacles 3,
4, 5 and 6 separately. It is only possible to separately control Bank 1 and Bank 2.
1100 and 1440 VA models: Receptacles 1 and 2 are Bank 1 and LEDs 1 and 2 will either be on
together or off together. Receptacles 3 and 4 are Bank 2 (LED 3) and receptacles 5 and 6 are Bank 3
(LED 4). It is possible to control Bank 1, Bank 2, and Bank 3 independently from each other.
Site Wiring Fault Indicator – (North American Versions Only)
A red Site Wiring Fault LED is located on the rear panel of the UPM. This LED is designed to illuminate if
the UPM is connected to an improperly wired AC receptacle. This indicator is designed to indicate a missing
safety ground wire or a reversal in phase and neutral wiring. This indicator should be visually checked
during installation and, if illuminated, you should contact a qualified electrician immediately.
Note: Do not operate the UPM if the Site Wiring Fault LED is illuminated. When lit, the LED is indicating a
wiring condition, which may represent a hazard of fire or electrocution. In addition, improper wiring may
create reliability problems for both the UPM and the connected system. Never use a 3 blade to 2-blade
adapter (often called a “cheater”) with the UPM. These devices remove the safety ground connection to the
UPM and will cause the Site Wiring Fault LED to illuminate.

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER

Communication Manager Port
Communication Manager provides a connection port on the rear panel of the UPM. Connecting to this port
and installing Communication Manager’s software package (optional), will allow you control over important
UPM functions and access to operating information from the UPM. Using Communications Manager’s
software, you can view such parameters as AC input and output voltage, powerline frequency, and battery
voltage. The following table illustrates the available parameters.
Input Voltage Indicates the actual input voltage to the UPM
when AC power is present
Output Voltage Indicates the actual output voltage of the UPM
AC Frequency Indicates the actual output frequency of the UPM
Battery Voltage Indicates the actual DC voltage of the internal
battery buss
Change Battery Indicates the battery is incapable of holding a
charge and requires replacement
Percent Load Indicates the percentage of VA capacity being
used by connected load
Temperature Indicates the actual internal temperature of the
UPM
Communications Manager also can support simple software programs that rely on basic “contact closure”
signaling from the UPM. An example would be the built in UPS Service provided in Windows® NT. The
functions of basic software control usually include the following:
Broadcast warnings of power failures/timed shutdowns
Automatic closure of files prior to battery exhaustion
Power down of the UPM and connected equipment
To support these functions without the Communications Manager software suite, you will need to either buy
or build your own special cable. The following table describes the pin assignment of the DB9 connector on
the rear of the UPM. Contact your computer supplier to determine the connection
configuration and connector style necessary to attach the cable to the computer.
Pin # Description
1 UPM simulates a relay opening between Pins 1 and 4 when
input power fails
2 UPM simulates a relay closing between Pins 2 and 4 when
input power fails
3 UPM sends a RS232 high (12V) 1 second after input power
fails (normally low)
4 Common Ground
5 UPM simulates a relay closing when battery has less than 2

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER

minutes runtime left*
6 User sends a RS232 high (5-15V) for 3 seconds. This signal
turns off the UPM until normal input voltage returns. This
signal operates only if the UPM is in battery mode. Pin 6
also functions as the RS232 receive data.
7 Common Ground
8 Reserved
9 RS232 transmit data
* Load Dependent
Notes:
1. Pins 1, 2, and 5 are open collector outputs, which must be pulled up to a common referenced supply.
Switch rating: +40V, 0.15A non-inductive.
2. Pins 4 and 7 should only be connected to ground.
Important Note: You may, of course, connect your computer to the UPM without using
Communications Manager. When power is lost, the UPM will beep and you will have to
manually shut down the computer and UPM.
Configuration Manager
Configuration Manager provides control over important operation parameters of the UPM. Configuration
Manager controls these parameters through the settings on the DIP (dual inline pin) switch pack on the rear
panel and also through certain selections accessed by Communications Manager software.
Operating Voltage: The DIP switches can be used to configure the UPM operating voltage. For North
American models, the UPM can be configured to operate at 100, 110, 115, or 120 volts. International
models can be configured for 220, 230, or 240 volts. The following table illustrates the required switch
settings for each selection.
Voltage Required SW#1 SW #2 SW #3 SW #4
120V/240V Off Off Off Unused
115V/230V On Off Off Unused
110V/220V Off On Off Unused

Low Battery Warning Time: Low battery warning time can be configured for either two or five minutes
before UPM shutdown depending on the requirements of the application. It should be noted that these times
are at full load with a healthy battery. Partial loads and/or aged batteries will affect the accuracy of this timer
setting.
Receptacle On/Off Control: Set the turn-off times of the receptacle groups and individual receptacles on
the rear panel.
Start Manager
When AC power is not available, such as in a new installation where wiring may be incomplete, you can still
start the UPM to test its operation and the operation of your system using Start Manager. With the UPM off,
follow these simple steps:
1. Disconnect the input AC power cable from the rear panel of the UPM.
2. Set the rear panel Start Manager switch to “Enable”.
3. Press and hold the On/Off switch on the front panel until the UPM beeps.

ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER

4. The UPM is now running on battery. When you have finished, press the On/Off switch again and return
the Start Manager switch to the “Disabled” position. Plug the input AC power cable into the rear panel
of the UPM.
7.0 – UNPACKING, INSPECTION, TESTING AND TROUBLESHOOTING
Please Note: Before installation, please read and understand the following instructions. Carefully examine
the packing carton for damage. Notify the carrier immediately if damage is observed. Be sure to save the
carton should you ever need to ship the UPM for repair or maintenance.
Placement
This UPM is intended for indoor use only. Although your UPM is very rugged, its internal
components are not sealed from the environment. The UPM must be installed in a
protected environment away from heat producing appliances such as furnaces, radiators,
and heaters. Protect the UPM from exposure to dripping or standing water and high
humidity or condensing air conditions. The location should provide adequate airflow
around the UPM. Provide a minimum 1” clearance on all sides for proper ventilation.
Applying Power to the UPM
For North American versions, connect the power cord to a verified grounded 3 wire receptacle. For
international versions, unplug the cord from your computer and plug into the inlet of the UPM. Then use the
cord supplied with the UPM to connect the UPM to your computer.
For North American versions, verify that the Site Wiring Fault LED is off. Once properly connected and
initially checked, turn on the UPM by pressing and holding the front panel On/Off switch for 3 seconds.
Operational Tests

Note: Depending on the charge state of the battery, it is possible that some of the Battery Monitor
LEDs may be off.
With the connected equipment powered off, perform an initial test of the UPM backup function by pressing
the Test/Silence button on the front panel. During this test, the Battery Mode LED on the front panel should
briefly illuminate. It is also possible to test the backup function by unplugging the UPM input power cord. If
you choose to test the UPM in this manner, you will note that the UPM will beep every four seconds while
the power cord is unplugged. The Battery Mode LED will also illuminate constantly.
Once you have performed an initial test of the UPM backup function, turn on the connected computer
equipment. Verify that the Overload LED is off. If the Overload LED is illuminated, remove the least critical
devices from the UPM one by one until the overload light is extinguished. With the connected loads
powered up, perform the backup test once again by pressing the Test/Silence button or unplugging the
UPM. When this final test is completed, the UPM will be ready to use.
Please Note:
If you leave your UPM on continuously, it is a good idea to perform a test at least once a month.
If you are utilizing Communications Manager software, you can configure the system to
automatically self-test periodically.
The UPM is shipped with a charged battery, but some discharge naturally occurs during storage
and shipment. You may use the UPM immediately, but you should realize that backup time may
be less than the stated rating until the UPM battery has had at least six hours to charge.
ETA SYSTEMS recommends that you do not plug laser printers into the
UPM. Laser printers are known to draw large amounts of current when the
fuser/heater assembly is energized. Laser printers can easily overload the
UPM or create a low voltage condition that can interfere with the operation
of the Voltage Manager circuit.
Storage
The UPM may be stored for extended periods in an environment that does not subject the UPM to extremes
of temperature or humidity. When storing for extended periods, the battery should be charged every 3
months. If the storage location is characterized by above normal temperature, the battery should be
recharged every two months. The UPM does not need to be turned on for charging to occur – it only needs
to be plugged in.
Note: This product is not designed for continuous use on batteries.

Important Information
The batteries inside this UPM are a special type called “sealed lead-acid”. These batteries use a non-liquid
electrolyte, which makes it possible to use them in any physical orientation. The batteries are designed to
last from 2 to 5 years. Their actual life span will depend on several factors including how often power
outages occur, how long power outages last, and the temperature of the environment in which the UPM
operates. Frequent, long duration power outages will shorten battery life more than infrequent, short
duration outages. Consistent high temperatures in the area where the UPM is used will also shorten battery
life.
The UPM is equipped with a Low/Replace Battery LED on the front panel. If the LED illuminates, you should
make sure that the battery has at least six hours to charge without a power interruption. Inadequate (much
shorter than usual) backup time, premature low battery alarm sounds, and persistent Low/Replace Battery
LED illumination are all good signs that the battery inside your UPM requires replacement. The batteries
inside your UPM are designed to be easily replaced by a user who possesses basic mechanical/electrical
knowledge and simple tools. Please familiarize yourself with the following precautions before proceeding
with battery replacement.
WARNING !!
Servicing of batteries should always be performed or supervised by
someone who has read and understood the following precautions and who
understands the hazards associated with storage batteries. This procedure
should not be performed by someone who is unauthorized or who is
incapable of following these precautions.
OBSERVE THE FOLLOWING CAUTIONS
"Only the battery assembly in this unit is user serviceable. The battery compartment is
accessed by removing the front panel as described in the following instructions. No
other user serviceable parts are contained in this UPM. Do not remove any cover
other than the front battery access panels.
"A battery (even a depleted one) can deliver very high currents when short-circuited.
There is a danger of electrical shock. Remove all watches, rings, bracelets or other
metal objects. Use only tools with insulated handles.

"Do not dispose of batteries in a fire. There is a danger of explosion. Do not dispose of
batteries in an environmentally unfriendly manner. Batteries may be returned to ETA
SYSTEMS for proper disposal.
"Do not open or mutilate the batteries. This may release electrolyte that is toxic to the
environment and harmful to the skin and eyes.
"Replacement batteries may be ordered from ETA SYSTEMS by phone at (800) 321-
6699. If purchasing batteries from another source, be sure to use the type and
quantity of batteries described in the table in Section 10.
8.0 – USER REPLACEABLE BATTERY
Please note: Changing the batteries in this UPM is designed to be a safe and simple procedure. Batteries
may be replaced while the UPM is on and providing power to the connected load. You should remember,
however, that if a power outage occurs after the old batteries are disconnected and before the new batteries
are installed, power will be lost to your connected system and components.
Please note: If you have read and understood the cautions preceding this section, you may proceed with
the following steps. Consult Figure 6 to assist you in the following battery replacement procedure.
Battery Replacement
1. Remove the two small screws from the bottom of the front panel that secure the front panel to the frame
of the UPM.
2. Carefully slide the front panel off the UPM taking care not to damage or tear the ribbon cable that
connects the front panel “dashboard” display to the UPM.
3. Remove the screw(s) that secures the battery assembly retaining bracket, remove it from the unit, and
set it to one side.
4. Slide the battery pack from the UPM by pulling on the tab provided.
5. Disconnect the battery from the UPM by pulling apart the wire leads at the connector(s) provided.
6. Connect the new battery pack to the UPM by reconnecting the connector(s) making sure to observe
proper polarity (i.e. black to black and red to red).
