1. Overview
Marathon Power's Track models are ideal for more critical applications where a true sine wave
output while in backup mode is required along with the efficiency of a line-interactive design. Tap-
changing AVR (Automatic Voltage Regulation) provides mitigation of sags and swells without the
need to transfer to battery. Battery energy is conserved for more severe disturbances such as
interruptions and outages.
Tight voltage and frequency regulation along with fast transfer ensures the seamless transfer of
uninterrupted power to the load. Included is generic power monitoring & UPS control software.
They feature a unique energy saving “Sleep Mode” that reduces the cost of ownership and
“Cold Start” that allows the UPS to be used as a small emergency power source.
Using the UPS with the included software* and interconnecting cable allows intelligent control of the
system when linked to a host computer. (Some operating systems require other optional software)
There are dry contacts or solid state signalling via astandard RS-232 port that allowsfor remote
notification of basic functions such as Power Normal, Backup Mode, & Low Battery states.
* Software is presently available for PC operating systems only.
2. Safety
WARNINGS AND CAUTIONS!
Please be aware of, and observe the following:
• To reduce the risk of electric shock, disconnect the UPS from the main AC supply before installing any
interface cables. Reconnect the power cord only after the signaling interconnections have been made.
• The internal energy source (the battery) cannot be de-energized by the user. The output may be
energized when the unit is not connected to the AC supply.
• The correct way to de-energize the UPS properly in an emergency is to move the I/O switch to the
OFF position and disconnect the power cord from the main supply.
• Even when the unit is disconnected, risk of electric shock from parts energized by the battery inside unit
still exists. To avoid this, the battery supply should be disconnected at positive and negative terminals.
• The outlet sockets should be installed near the equipment and easily accessible.
• Do not dispose of batteries in a fire as they may explode. Please contact tech support for proper
disposal instructions.
• Do not open or attempt to dismantle the battery, as electrolyte that is harmful to the skin and eyes
may be released.
• A battery can present a risk of electric shock and high short circuit current. The following precautions
should be taken when working with them:
- Remove watches, rings and other jewelry or metal objects.
- Use tools with insulated handles.
• To reduce risk of fire, replace only with same type and rating of fuse.
• To reduce the risk of fire or electric shock, install the UPS in a temperature and humidity controlled
indoor area free of conductive contaminants.

Use the self-test to verify both the operation of the UPS and the condition of the battery. To
perform the self-test, press the ON/TEST button more for more than 1 second, but less than 2
seconds, under normal power conditions. During the self-test, the UPS will operate in back-up mode.
NOTE: During the self-test, the load(s) use battery energy. The “ON BATTERY” LED or BACKUP
LCD icon will illuminate indicating the UPS is supplying power.
If the UPS passes the self-test, it will return to normal on-line operation. The “ON BATTERY” LED
or BACKUP LCD icon will turn OFF and the “ON LINE” LED or INV LCD icon will illuminate.
If the UPS fails the self-test, it immediately returns to on-line operation and the “REPLACE
BATTERY” LED or LCD error code will illuminate, however the loads are not affected. Recharge
the battery overnight and perform the self-test again. If the “REPLACE BATTERY” LED or LCD
error code is still illuminated, call tech support for battery replacement instructions.
5.4 Audible Alarm Silencing
To silence the audible alarm, press the “ON/TEST” button for less than one second while the UPS is
in back-up mode.
NOTE: This function will not work when the UPS is under “Low Battery” or “Overload” conditions.
NOTE: In back-up mode, the UPS will automatically turn OFF if none of the connected loads are active.
5.5 Load Bar Graph
The 5 LED or LCD segment display indicates the power drawn from the UPS by the load. The
number of illuminated LEDs or segments represents the percentage of the UPS's rated capacity
being utilized. For example, if two LEDs or segments are illuminated, the load is drawing between
20% and 40% of the UPS's rated capacity.(See section 3 for location of the display on the front panel)
If the UPS is overloaded, the “OVERLOAD” LED or LCD error code illuminates and an alarm sounds.
5.6 Battery Charge Bar Graph
The 5 LED or LCD segment display shows the present charge of the UPS's battery as a percentage
of the battery capacity. When all 5 LEDs or segments are illuminated, the battery is fully charged.
(see section 3 for location of the display on the front panel).

power failure. In addition, it displays diagnostic features, such as: input and output voltage,
frequency, battery and load level visually on your computer monitor.
The software is usable with DOS, Windows 3.1x or higher, Windows NT V3.5 or later, and others.
Contact tech support for more information on alternative computer OS compatible software.
7.2 Interface Kits
Included interface kit provides UPS monitoring. Each kit includes a special cable to convert status
signals from the UPS into signals which individual operating systems recognize. One end of the
cable is connected to the remote port on the UPS and the other end to either the COM 1 or COM 2
port on the computer.An SNMP/WEB network card or module is also available for most models.
NOTE: Use only a factory supplied or authorized monitoring cable.

8. Care & Maintenance
1. Keep the unit clean and vacuum the ventilation intake periodically.
2. Wipe with a soft, damp cloth.
3. Check for loose and/or bad connections monthly.
4. Never leave the unit on an uneven surface.
5. Position the unit to allow at least 1/2” (1.3 cm) clearance between the rear panel and the wall.
6. Keep the ventilation intake(s) open.
7. Avoid direct sunlight, rain, and high humidity.
8. Keep away from fire and extremely hot locations.
9. Do not stack anything on top of the unit.
10.The unit should not be exposed to corrosive environments.
11.Normal operating temperature is 32 to 104°F (0-40°C).
9. Computer Interface Port
1. The communication port on the back of the UPS may be connected to the host computer. The
port allows the computer to monitor the status of the UPS and, in some cases, control the
operation of the UPS.
2. Major functions include some or all of the following:
•Power disturbance notification.
•Closure of any open files prior to battery depletion.
•UPS power-up or OFF.
3. Although most computers are equipped with a connector (via COM port) to allow a link to the
communication port on the back of the UPS, a special plug-in card may be needed in the event
one is not available. Some computers may also need special software. Contact tech support for
details on various interface kits.
4. The computer interface port has the following characteristics:
•Pin 5 and 2 are open collector outputs which must be pulled up to a common reference
supply of no greater than +40 VDC.
•The transistors are capable of a maximum nonconductive load of 25 mA DC. Use pin 7 only
as the common.
•Pin 5 generates a High to Low signal when the battery inside the UPS has less than 5 minutes
back-up time left.
•Pin 2 generates a High to Low signal when the line fails.
•The UPS will shut down when a high RS-232 level is sustained on pin 6 for 0.36 seconds.
•Pin 9 is also used for RS-232 data output.
•Pin 6 is used for the RS-232 data input (RxD).
NOTES:
•Switch rating +40V,
0.15A non-inductive.
•Pin 7 should be
connected to ground
only.
