26 Setting Up Your Computer
Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
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).
