5.0 – OVERVIEW
General
The ETA Systems Security One Series of Uninterruptible Power Supplies 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. Security One UPM
solutions will protect your installation from normal mode voltage impulses, electrical noise, sags and surges,
protracted brownouts, and complete blackouts. And because each Security One 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, Security One
constantly filters and conditions the power supply. When AC power fails, Security One uses its internal,
maintenance-free battery to supply reserve power to your computer system. Regardless of whether or not
commercial power is present, Security One 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 Security One UPM.
Sinewave Output
The output voltage of all Security One 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 your computer
system). 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 Security One UPM products feature Voltage
Manager – a circuit that constantly monitors the AC power source. If minor changes in AC voltage occur,

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
6
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 enables the internal batteries and allows you to start the Security One
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.
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 Security One 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 Security One 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 Security One 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 Security
One 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 Security One UPM
to last a minimum of two years – perhaps longer if power outages are short and infrequent. Security One
makes battery replacement by the user easy and fast. And it’s not necessary to turn off the UPM or the
connected system. Security One allows the battery to be “hot-swapped” while the system is running.

6.0 – OPERATION
Important Note:In order to operate the UPM, you must first plug the battery enable plug(s) into the
battery enable socket(s) on the rear of the UPM.
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 battery enable plug(s) are installed, 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.
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.

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
8
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 Security One’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
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).
420 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.
600 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.

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
9
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.
Communication Manager Port
Communication Manager provides a connection point on the rear panel of the UPM (both DB9 and USB
ports). 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:

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
10
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 Reserved
2 UPM simulates a relay closing between Pins 2 and 4 when
input power fails
3 Reserved
4 Common Ground
5 UPM simulates a relay closing when battery has less than 2
minutes runtime remaining*
6 UPM sends a RS232 high (12V) for 1 second after input
power fails (normally low). Also functions as 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.

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
11
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
100V/208V On Off Off Off
110V/220V Off On Off Off
120/230V Off Off On Off
127/240V Off Off Off On
If Communications Manager software is installed on the host PC, Configuration Manager can use it to adjust
both Low Voltage Transfer Point and High Voltage Transfer Point. The following table provides the
allowable set points for adjusting transfer voltage (key in all three numbers shown).

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. Ensure that the battery enable plug(s) are inserted into the rear panel battery enable socket(s).
3. Press and hold the On/Off switch on the front panel until the UPM beeps.
4. The UPM is now running on battery. When you have finished, press the On/Off switch again. 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.

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
13
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.

ETA Systems®- SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
14
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.
Troubleshooting
The troubleshooting information provided in this section should help you discover the cause of most
commonly encountered difficulties. Before following the troubleshooting steps provided, be certain that you
have verified the following items:

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 or via our website
at www.ETA Systems.com. 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.
