1. Overview
The Sprint series is made up of a broad range of line-interactive models in both Tower and
19" Rack-Mount configurations. Line interactivity implies Automatic Voltage Regulation which
uses buck / boost circuitry to correct for input voltage variations ranging from 75% to 125% of
nominal, without the need to transfer to battery,while maintaining a constant output to the load.
Theyfeature microprocessor control of battery charging and since this is a continuous function,
there is no need to switch the UPS on in order for charging to be activated. Toreduce the cost of
ownership, the units turn off automatically ("Sleep Mode") if none of the connected equipment is
operating. There is battery replacement indication and a cyclical self-test function that verifies
both UPS operation and battery condition. They also feature a “cold-start” function that
allows the user to power-up the load directly from the UPS without the availability of utility power.
In addition, the UPS provides single telephone line or modem surge suppression through the
modular connectors on the rear panel, as well as on the AC output receptacles.
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 may require the use of
other optional software).
Dry contacts, accessible via the standard RS-232, connector, allow for remote signalling of basic
functions such as Power Normal, Backup Mode, and Low Battery states as well as Remote Shutdown.
*Software is presently available for PC operating systems only. Later versions may be available
for Macintosh operating systems.
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 a computer interface cable. 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 the unit
still exists. To avoid this, the battery supply should be disconnected at the 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 only kits and/or cables supplied or approved by manufacturer. See section 7 for additional info.
NOTE: The computer interface connection is optional and not necessary for the UPS to function correctly.
4.9 Rack Mount Models
Depending on installation, 19" rack-mount applications may require the use of guide rails and/or
brackets to support the weight of the UPS. Please contact the manufacturer of your rack or
enclosure to purchase suitable mounting/installation hardware.
A Note on RFI (Radio Frequency Interference)
There is no guarantee that interference to a radio or TV receiver will not occur in a particular
installation. If the UPS causes interference to radio or television reception, which can be
determined by turning the UPS OFF and ON, the user is encouraged to try to rectify the problem by
trying one or more of following:
• Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.
• Increase the separation between the equipment and the receiver.
• Re-orient the receiving antenna.

1000VA Rack-Mount ONLY Note:To turn the unit on, toggle ON/OFF switch to ON position.
With the UPS plugged in, press the ON/TEST button more than 2 seconds to energize the UPS. It
will perform a self-test each time it is switched ON.
NOTE: When switched OFF, the UPS will maintain and continue to charge the battery and also
respond to commands received through the computer interface port.
5.2 Turn-OFF
1000VA Rack-Mount ONLY Note: To turn the unit off, toggle ON/OFF switch to OFF position.
Press and hold the OFF button until the “LINE NORMAL” or “BACKUP” LED turns OFF.
5.3 Self-Test
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 will illuminate,
(or flash) indicating the UPS is supplying battery power.
If the UPS passes the self-test, it will return to normal on-line operation. The “ON BATTERY” LED
will turn off and the “ON LINE” LED will illuminate.

If the UPS fails the self-test, it immediately returns to on-line operation and the “REPLACE
BATTERY” LED will illuminate. The loads are not affected. Recharge the battery overnight and per-
form the self-test again. If the “REPLACE BATTERY” LED 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. On the 1000VA Rack-Mount model, press the BUZZER button
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 OFFif none of the connected loads are in
operation or if they consume less than 15 watts ("Sleep Mode").This feature can be disabled if necessary.
5.5 Cold Start
When the UPS is OFF and there is no utility power available or present, the cold start feature can
be used to apply power to the loads from the UPS using the battery as the power source. Press the
ON/TEST button until the UPS beeps.
1000VA Rack-Mount ONLY Note: With UPS unit OFF and no utility power, toggle ON/OFF switch
to ON position
5.6 Shutdown Mode
In this mode, the UPS ceases supplying power to the load while waiting for the return of utility
power. If utility power is not restored, an external device such as a server connected to the
computer via the interface can command the UPS to shutdown. This is typically done to preserve
battery capacity after the proper shutdown of protected loads.
6. Alarms
6.1 “BACKUP” (slow alarm)
When in back-up mode, an LED illuminates (or flashes) and the UPS sounds an audible alarm.
The alarm stops when the UPS returns to LINE NORMAL operation.
The alarm can be silenced by briefly pressing the “ON/TEST” button when the on-battery alarm
sounds.
6.2 “LOW BATTERY” (rapid alarm)
In back-up mode, when the battery level runs low, the UPS beeps rapidly until either the UPS shuts
down due to battery depletion or it returns to LINE NORMAL operation.
6.3 “OVERLOAD” (continuous alarm)
When the UPS is overloaded (i.e., the connected load(s) exceed the maximum rated capacity) the
UPS emits a continuous tone to warn of an overload condition. Disconnect non-critical loads from
the UPS to eliminate the overload.
6.4 “REPLACE BATTERY” (continuous alarm) (Some models only)

14. Warranty
14.1 Limited Three-Year Warranty and Exclusions
NOTE: For this warranty to be valid, completed registration information must be received within 30 days of original purchase.
Marathon Power warrants to the original purchaser, who must have properly registered the product within
30 days of purchase, and not for the benet of anyone else that this product at the time of its sale by
Marathon Power is free of defects in materials and workmanship for three (3) years (batteries for 2 years
within the USA, Canada and Mexico, otherwise 1 year) from the original purchase date. Marathon Power
will correct such defects by repair or replacement, at its option, if within such three year period the product is
returned prepaid and all warranty claim instructions are followed. This warranty excludes labor for removal
or reinstallation of this product. This warranty is void if this product is installed improperly or in an improper
environment, overloaded, misused, opened, abused, or altered in any manner, or is not used under normal
operating conditions or not in accordance with all labels or instructions. There are no other or implied
warranties of any kind, including merchantability and tness for a particular purpose, but if any implied
warranty is required by the applicable jurisdiction, the duration of any such implied warranty, including
merchantability and tness for a particular purpose, is limited to three years. Marathon Power is not liable
for incidental, indirect, special or consequential damages, including damage to, or loss of use of, any
equipment, lost sales or prots or delay or failure to perform this warranty obligation.
14.2 Limitations & Claims
This warranty does not cover any Marathon Power UPS or any properly connected electronic equipment
which has been improperly installed, overloaded, abused or altered in any manner, or is not used under
normal operating conditions, or in accordance with any labels or instructions, and does not cover any
damage to properly connected electronic equipment resulting from a cause other than a “surge”.
Damage caused by failure to provide a suitable installation environment for the product (including, but
not limited to, lack of a good ground) will not be covered by this warranty. This warranty does not apply
to damage caused by direct lightning strikes, or damage caused by electrical disturbances that exceed
published product specications. These products are intended to limit the maximum amplitude of transient
voltage surges on power lines to specied values. They are not intended to function as surge arrestors.
The UPS is intended to be installed on the load side of the service entrance and has been tested to verify
that transient voltage surges are limited when subject to non-repetitive transient voltage surge events. This
warranty excludes any incidental, indirect, special or consequential damages, including without limitation,
labor for removal or reinstallation of the Marathon Power UPS or any connected electronic equipment,
data loss or alteration loss of equipment use, lost sales or prots and any such damages for delay or
failure to perform this warranty obligation. This warranty is in lieu of and excludes all implied warranties
of merchantability or tness for use. In addition, the warranty does not cover restoration of lost data and
reinstallation of software. Some states may not allow the exclusion or limitation of incidental or consequential
damages or other remedies, so the above exclusions or limitations may not apply to you.
Take the following stps to le a warranty claim: Contact us at Marathon Power, Inc., Attn: Returns, 2538 E.
54th Street, Huntington Park, California 90255 or call [phone] within 30 days of the occurrence. Be
prepared to provide detailed information about the event, any damage, the UPS model number, purchase
date and location. You will then be provided with a Return Authorization Number (RAN), and be instructed
to forward your proof of purchase (receipt), an explanation of the event and your UPS. If Marathon Power
determines that the damage was due to a “surge”, we may request that all connected equipment be submitted
for evaluation. Marathon Power is not responible for shipping costs. In the event that the equipment has
been damaged by a “surge” Marathon Power will reimburse you for repair or replacement at fair market
value (on a pro rata basis) as indicated by the respective amounts above. The warranty coverage is above
and beyond, only to the extent needed, of that provided by any other source, including but not limited to
any connected equipment coverage, any manufacturer’s warranty or insurance policy. To receive payment
for repair to damage due to a “surge,” the original purchaser should (upon prior approval from Marathon
Power) have such equipment repaired by an authorized service center of such equipment’s manufacturer.
The original purchaser will submit a repair bill along with a statement from the repair facility documenting
the nature of the damage and how it was sustained to said equipment.
