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).
