Application Precautions
Observe the following precautions when using the Controller Link Support
Board for PCI Bus or the computer into which it is installed.
Note Refer also to 1-4 Application Precautions for further information and additional
precautions.
WARNING
Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
•
Always ground the system to 100
Ω
or less when installing the system to pro-
tect against electrical shock.
•
Always turn OFF the power of the computer before attempting any of the fol-
lowing. Performing any of the following with the power supply turned on may
lead to electrical shock:
•
Installing or removing the Support Board.
•
Assembling the Units.
•
Setting DIP switches or short-circuiting pins.
•
Connecting or disconnecting any cables or connectors.
Caution
Failure to abide by the following precautions could lead to faulty operation of the
computer or the system or could damage the Controller Link Support Board for
PCI Bus or related devices. Always heed these precautions.
•
Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes.
•
Always use the power supply voltage specified in the operation manuals. An
incorrect voltage may result in malfunction or burning.
•
Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied. Be particularly careful in places where the
power supply is unstable. An incorrect power supply may result in malfunction.
•
Install external breakers and take other safety measures against short-circuit-
ing in external wiring. Insufficient safety measures against short-circuiting may
result in burning.
•
Disconnect the functional ground terminal when performing withstand voltage
tests. Not disconnecting the functional ground terminal may result in burning.
•
Do not attempt to take the Boards apart, to repair the Boards, or to modify the
Boards in any way.
•
Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in this manual. Incorrect tighten-
ing torque may result in malfunction.
•
Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals. Connection of bare stranded wires may result in burning.
•
Double-check all the wiring before turning ON the power supply. Incorrect wir-
ing may result in burning.
•
Wire correctly.
•
Double-check all the connectors before mounting the Board.
•
Be sure that the communications cable connectors and other items with lock-
ing devices are properly locked into place. Improper locking may result in mal-
function.
•
Use a special packing box when transporting the Board. Handle the product
carefully so that no excessive vibration or impact is applied to the product dur-
ing transportation.
