Before you install your STA-3108A1
CAUTION
Before you make any connections from an STA-3108A1 to a board in your computer, make sure that
power to your computer and any accessories is OFF.
Remember the following precautions when connecting any hardware to your system:
• Do NOT connect the STA-3108A1 to voltages above those tolerated by other boards in the system. Although the
STA-3108A1 is rated for 60 volts peak-to-peak, the board to which it is connected may be rated for a much lower
voltage. For example, KPCI-3108 analog inputs can only tolerate 35 volts peak without damage and digital I/O will be
damaged by voltages above +5V.
• Do NOT mix your data acquisition inputs with the AC line, or you risk damaging the computer. Data acquisition
systems give users access to inputs of the computer. An inadvertent short between data and power lines can cause
extensive and costly damage to your computer. The manufacturer can accept no liability for this type of accident. To
prevent this problem, use the following precautions:
— Avoid direct connections to the AC line.
— Make sure all connections are tight and sound so that signal wires are not likely to come loose and short to high
voltages.
— Use isolation amplifiers and transformers where necessary.
