OR OTHER LARGE ELECTRICAL DEVICE TO THE UPS. THE POWER DEMANDS OF THESE
DEVICES WILL POSSIBLY OVERLOAD AND DAMAGE YOUR UPS.
SERVICING OF BATTERIES SHOULD BE PERFORMED OR SUPERVISED BY PERSONNEL
KNOWLEDGEABLE OF BATTERIES AND THE REQUIRED PRECAUTIONS. KEEP
UNAUTHORIZED PERSONNEL AWAY FROM BATTERIES!
FOR PERMANENTLY CONNECTED EQUIPMENT, A READILY ACCESSIBLE DISCONNECT
DEVICE SHALL BE INCORPORATED IN THE BUILDING INSTALLATION WIRING.
RISK OF ELECTRIC SHOCK
A battery can present a risk of electric shock and high short circuit current. The following
precaution should be observed when working on batteries:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
The UPS must be connected to a grounded AC power outlet with fuse or circuit breaker
protection. DO NOT plug the UPS into an outlet that is not grounded. If you need to power-
drain this equipment, turn off and unplug the unit.

INSTALLING YOUR UPS SYSTEM
HARDWARE INSTALLATION GUIDE
1 . Battery charge loss may occur during shipping and storage. Before using the UPS,
it’s strongly recommended to charge batteries for four hours to ensure the batteries’
maximum charge capacity. To recharge the batteries, simply connect the UPS to its
designated AC electrical service.
2 . When using PowerPanel Business software, connect either the serial or the USB cable
between the computer and the corresponding port on the UPS. After connecting to
either the USB port or the serial port on the UPS, a computer with PowerPanel Business
Agent software installed can control the operating schedule, battery test, outlets, as well
as obtain UPS status information. However, other computers with PowerPanel Business
Client software can only obtain UPS status information via LAN connection.
3 . Connect your computer, monitor, and any externally-powered data storage device (Hard
drive, Tape drive, etc.) into the outlets only when the UPS is off and unplugged. DO NOT
plug a laser printer, copier, space heater, vacuum, paper shredder or other large electrical
device into the UPS. The power demands of these devices will overload and possibly
damage the unit.
4 . Press the ON/OFF switch to turn the UPS on. The Power-On indicator LED will turn on
when activated. If an overload is detected, an audible alarm will sound and the UPS will
continuously emit two beeps per second. For resetting the unit, unplug some equipment
from the outlets. Make sure your equipment carries a load current within the unit’s safe
range, (refer to the technical specifications).
5 . This UPS is equipped with an auto-charge feature. When the UPS is connected to AC
electrical service the battery will automatically charge, even when the unit is switched off.

INSTALLING YOUR UPS SYSTEM
6 . To maintain an optimal battery charge, leave the UPS connected to AC electrical service at
all times.
7 . Before storing the UPS for an extended period of time, turn the unit OFF. Then cover it
and store it with the batteries fully charged. Recharge the batteries every three months to
ensure good battery capacity and long battery life. Maintaining a good battery charge will
help prevent possible damage to the unit from battery leakage.
8 . The UPS has one USB port (default) and one serial port that allows connection and
communication between the UPS and any attached computer running PowerPanel
Business Agent software. The UPS can control the computer’s shutdown during a power
outage through the connection while the computer can monitor the UPS and alter various
programmable parameters.
9 . EPO (Emergency Power Off) / ROO (Remote on/off) Port: EPO/ROO ports allow
administrators the capability to connect the UPS unit to customer-supplied EPO/ROO
switches. If EPO is enabled, these installations give operators a single access point to
immediately power-off all equipment connected to the UPS during an emergency. If ROO
is enabled, these installations give operators an access point to turn on/off UPS remotely.
10 . To avoid electric shock, turn the unit OFF and disconnect the unit from utility power before
hardwiring the UPS (in/out power cord). The in/out power cord MUST be grounded.
11 . Please note the internal UPS temperature will increase when fans are not in operation or
ventilation is obstructed. When the high temperature sensor activates protection, the
UPS generates an alarm and shuts down to avoid unexpected equipment damage. When
the over temperature occurs, please check the Troubleshooting section. If the condition
persists, please contact CyberPower for technical support.
HARDWARE INSTALLATION
This UPS can be installed in a rackmount or vertical/tower orientation. This versatility is
especially important to growing organizations with changing needs that value having the
