IMPORTANT SAFETY WARNINGS
This manual contains important safety instructions. Please read and follow all instructions carefully during
installation and operation of the unit. Read this manual thoroughly before attempting to unpack, install, or operate
your UPS.
WARNINGS
• To prevent the risk of fire or electric shock, install in a temperature and humidity controlled indoor area free of
conductive contaminants. (Please see specifications for acceptable temperature and humidity range).
• To reduce the risk of electric shock, do not remove the cover. There are no user serviceable parts inside.
• Hazardous live parts inside can be energized by the battery even when the AC input power is disconnected.
• The UPS must be connected to an AC power outlet with fuse or circuit breaker protection. Do not plug into an
outlet that is not grounded. If you need to de-energize this equipment, turn off and unplug the unit.
• To avoid electric shock, turn off the unit and unplug it from the AC power source before installing a computer
component.
• Not for use in a computer room as defined in the Standard for the Protection of Electronic Computer/Data
Processing Equipment, ANSI/NFPA 75.
• To reduce the risk of fire, connect only to a circuit provided with 20 amperes maximum branch circuit over
current protection in accordance with the National Electric Code, ANSI/NFPA 70.
DO NOT USE FOR MEDICAL OR LIFE SUPPORT EQUIPMENT.
support or medical applications. DO NOT use in any circumstance that would affect operation and safety of life
support equipment, any medical applications or patient care.
DO NOT USE WITH OR NEAR AQUARIUMS. To reduce the risk of fire or electric shock, do not use with or near an
aquarium. Condensation from the aquarium can cause the unit to short out.
DO NOT USE THE UPS ON ANY TRANSPORTATION. To reduce the risk of fire or electric shock, do not use the unit
on any transportation such as airplanes or ships. The effect of shock or vibration caused during transit and the damp
environment can cause the unit to short out.
INSTALLING YOUR UPS SYSTEM
INTRODUCTION
Thank you for selecting a CyberPower Systems Uninterruptable Power Supply (UPS). This UPS meets the Energy
Efficiency Certification of the California Energy Commission (CEC). CyberPower Systems is dedicated to producing
energy efficient products to maximize our contribution to the environment.
UNPACKING
Inspect the UPS upon receipt. The box should contain the following:
(a) UPS unit (b) User's manual (c) USB device cable (except for ST425)
*PowerPanel® Personal Edition software is available on our website. Please visit
and go to the Software Section for free download.
HOW TO DETERMINE THE POWER REQUIREMENTS OF YOUR EQUIPMENT
Ensure that the equipment plugged into the UPS does not exceed the UPS unit's rated capacity. If the rated
1.
capacities of the unit are exceeded, an overload condition may occur and cause the UPS unit to shut down or
the circuit breaker to trip.
There are many factors that can affect the amount of power that your electronic equipment will require. For
2.
optimal system performance keep the load below 80% of the unit's rated capacity.
HARDWARE INSTALLATION GUIDE
1. Your new UPS may be used immediately upon receipt. However, after
receiving a new UPS, to ensure the battery's maximum charge capacity, it is
recommended that you charge the battery for at least 8 hours. Your UPS is
equipped with an auto-charge feature. When the UPS is plugged into an AC
outlet, the battery will automatically charge whether the UPS is turned on or turned off.
2. With the UPS unit turned off and unplugged, connect your computer, monitor, and any other peripherals
requiring battery backup into the battery power supplied outlets. Plug the other peripheral equipment (e.g.
printer, scanner, speakers, etc.) into the full-time surge protection outlets.
laser printer, paper shredder, copier, space heater, vacuum cleaner, sump pump, or other large electrical
device into the "Battery and Surge Protected Outlets". The power demands of these devices will overload
and possibly damage the unit.
3. Plug the UPS into a 2 pole, 3 wire grounded receptacle (wall outlet). Make sure the wall branch outlet is
protected by a fuse or circuit breaker and does not service equipment with large electrical demands (e.g. air
conditioner, refrigerator, copier, etc.). The warranty prohibits the use of extension cords, outlet strips, and surge
strips in conjunction with the UPS unit.
4. Press the power switch to turn the unit on. The Power On indicator light will illuminate green and the unit will
"beep" twice.
5. If an overload is detected, an audible alarm will sound and the unit will emit one long beep. To correct this,
turn the UPS off and unplug at least one piece of equipment from the battery power supplied outlets. Make
sure the circuit breaker is depressed and then turn the UPS on.
6. To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times.
7. To store the UPS for an extended period of time, cover it and store with the battery fully charged.
While in storage, recharge the battery every three months to ensure optimal battery life.
8. Ensure the wall outlet and UPS are located near the equipment being attached for
proper accessibility.
Lay the UPS horizontally or use the key-hole mounting slots to affix the UPS to the wall
9.
in the proper orientation. DO NOT stand the UPS up vertically.

1. Power Switch
• To turn the UPS on, press the power button for approximately 2 seconds - you will hear a constant tone (1
second) - and release after a short beep.
• To turn the UPS off, press the power button for approximately 2 seconds - you will hear a constant tone (1
second) - and release after two short beeps.
• Alarm setting: The audible alarm can be turned OFF or ON by quickly pressing the POWER button twice.
The default setting is for the Alarm On. To turn the Alarm Off, quickly press the power button twice. You
will hear two short beeps when the Alarm is turned off. To turn the Alarm back ON, quickly press the
power button twice. You will hear a single short beep when the Alarm is turned on.
*When the Alarm is turned off, there will be no audible notification when the UPS reaches a low battery
state.
2. Power On Indicator
This LED is illuminated when the utility power is normal and the UPS outlets are providing power, free of surges
and spikes.
3. Battery and Surge Protected Outlets
The unit has several battery powered and surge protected outlets to ensure temporary uninterrupted
operation of your equipment during a power failure. (DO NOT plug a laser printer, paper shredder, copier,
space heater, vacuum cleaner, sump pump, or other large electrical device into the "Battery and Surge
Protected Outlets." The power demands of these devices will overload and possibly damage the unit.)
4. Full-Time Surge Protection Outlets
The unit has several surge suppression outlets.
5. Circuit Breaker
Located on the side of the UPS, the circuit breaker provides overload and fault protection.
6. USB Port to PC (except for ST425)
The port allows connection and communication between the USB port on the computer and the UPS unit. The
UPS communicates its status to the PowerPanel
7. USB Charging ports (except for ST425)
The USB charging ports provide 5V 2.1A power output.
8. Outlets Designed for AC Adapters
The UPS unit has four widely-spaced outlets, so AC power adapters can be plugged into the UPS without
overlapping or blocking adjacent outlets.
