Uninterruptible Power Supplies

NOTICE: Loss of power while data is being saved to the hard drive may result in data loss or
file damage.
NOTE: To ensure maximum battery operating time, connect only your computer to a UPS.
Connect other devices, such as a printer, to a separate power strip that provides surge
protection.
A UPS protects against power fluctuations and interruptions. UPS devices contain a battery
that provides temporary power to connected devices when AC power is interrupted. The
battery charges while AC power is available. See the UPS manufacturer documentation for
information on battery operating time and to ensure that the device is approved by
Underwriters Laboratories (UL).
