IMPORTANT SAFETY INSTRUCTIONS!
SAVE THESE INSTRUCTIONS!
This manual contains important instructions for your Patriot SMT.
CAUTION!
Whenever the unit’s On/Off switch is on, there may be dangerous voltage present at
the unit’s outlets. This is true because the unit’s battery supplies power even if the
unit is not plugged into the wall outlet.
To reduce the risk of electric shock, install in a temperature-controlled and humidity-
controlled indoor area free of conductive contaminants.
The power supply cord is intended to serve as the disconnect device. The socket-outlet
shall be near the equipment and shall be easily accessible.
All standby power supply units contain dangerous voltages.
Before maintenance or repair, all connections must be removed. Before maintenance,
repair, or shipment, the unit must be completely switched off and unplugged or
disconnected.
The installation and use of this product must comply with all national, federal, state,
municipal, or local codes that apply. For assistance, call your local Best Power office.
Refer to your Patriot Safety Information Manual (ILS-1080) for additional safety
instructions.
If the Patriot unit has been damaged during shipment, call your vendor immediately.

Introduction
The Best Power Patriot standby power system provides protection against power problems,
®
including power outages, brownouts and sudden increases in power. It also provides spike
suppression and line noise filtering to protect your equipment. Front panel LEDs and an
audible beep keep you aware of the unit’s status. Use the drawings below to familiarize
yourself with the unit.

ENGLISH3
Starting the Unit
Plug the provided power cord into the unit’s input
1connector. Then, plug the other end into a wall outlet.
CAUTION!
Whenever the unit’s On/Off switch is on, there
may be voltage present at the unit’s outlets.
Push down the On/Off switch to turn the unit on.
2The green LINE LED will come on.
Let the unit charge the battery for 6 hours. You
3may use the unit while the battery charges.
However, the battery backup runtime will be low
until the battery is fully charged.
Switch off the load equipment and plug it into the
4outlets on the back of the unit.
Switch on the load equipment one piece at a time.

Please fill out the warranty registration card and
6return it to your local Best Power office. If you are
in the U.S.A. or Canada and you would like to
activate the Warranty for the Transient Voltage
Surge Suppression Circuitry, please return the
registration card within 10 days of installation.

ENGLISH 4
LEDs and Audible Beeps
The front panel LEDs and an audible beep indicate the unit status. The unit sounds a series
of beeps every five seconds whenever the unit is on battery power or an alarm is present. The
number of beeps varies depending on the unit status. See Table 2.
Table 1: LEDs
LED What it Means
LINE
(Green) Steady: Acceptable input power is present. The unit is running on line power.
Blinking: The unit detects unacceptable input power.
Off: Either no input power is present or the unit is switched off.
BATTERY/ALARM
(Yellow) Steady: The unit is running on battery power.
Blinking: An alarm is present.
Table 2: Audible Beeps
Number
of Beeps What it Means
1The unit is on battery power. See Table 3 for more information.
2Low Battery Alarm: The unit was running on battery power and shut down due to very low
battery voltage. The unit will restart automatically when acceptable input power returns.
3Near Low Battery Alarm: The runtime remaining is low. The unit will shut down soon. Shut off
the load equipment, but do not shut off the Patriot unit.
4Output Overload Alarm: Too much load equipment is connected to the unit. The unit will shut
down. Decrease the amount of load equipment connected to the unit. Then, reset the unit by
switching the On/Off switch off, then back on.
5
High AC Input Alarm: The input voltage is too high. Shut off the load equipment and the unit.
Unplug the unit. Look at the label on the bottom of the unit and make sure that the unit’s input
voltage rating is the same as the wall outlet voltage. If the unit’s input voltage rating is correct,
try a different wall outlet. If the alarm persists, shut off the unit and unplug it, then phone Best
Power’s Worldwide Service.
6High Battery Alarm: The battery voltage is too high. Shut off the load equipment and the unit.
Then, phone Best Power’s Worldwide Service.
7Shutdown: The unit has shut down due to a shutdown request issued by a device connected to
the DB9 communication port. See “Communication Port Pin-Outs” on page 8.

Replacing the Fuse
To replace the fuse, follow the steps below. The back panel drawings on page 3 show the
location of the fuse holder.
Switch off the Patriot unit and all of the load equipment. Unplug the Patriot unit and the
1load equipment. Disconnect the line cord from the back of the unit.
The top of the fuse holder has a small notch. Place a screwdriver into this notch and
2gently pry the fuse holder out of the unit.
One spare fuse is provided in the fuse holder. If the spare
3fuse has been used, call Best Power to order a new fuse.
The new fuse must be the size and type listed on the
label below the fuse holder.
Push the spare fuse out of the fuse holder.
4Remove the old fuse and put the new fuse in its place. Then, push the fuse holder back
5into the unit until it clicks into place.
Reconnect the line cord to the back of the unit. Plug the load equipment back into the
6unit. Plug the unit into the wall outlet. Switch on the unit.
Before switching on the load equipment, let the Patriot unit run for five minutes.
7Make sure that the green LED stays lit.
!If the fuse blows again (the green LED goes off and the yellow LED comes on), call
your local Best Power office.
!If the unit runs on line (the green LED stays lit) for five minutes, the original fuse
may have blown due to an overload of equipment on the unit. You may need to
reduce the amount of load equipment.
Switch on the load equipment one piece at a time.
