Uninterruptible Power Supply (UPS) 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. An uniterruptible power supply (UPS) protects against power fluctuations and interruptions.

See the UPS manufacturer documentation for information on battery operating time and to ensure that the device is approved by Underwriters Laboratories (UL).
