Caution The operating environment of the PC System can have a large effect on the lon-
gevity and reliability of the system. Improper operating environments can lead to
malfunction, failure, and other unforeseeable problems with the PC System. Be

5 Application Precautions
Observe the following precautions when using the PC System.
WARNING Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
Always ground the system to 100 or less when installing the Units. Not con-
necting to a ground of 100 or less may result in electric shock.
Always turn OFF the power supply to the PC before attempting any of the fol-
lowing. Not turning OFF the power supply may result in malfunction or electric
shock.
Mounting or dismounting I/O Units, CPU Units, Memory Cassettes, or any
other Units.
Assembling the Units.
Setting DIP switches or rotary switches.
Connecting cables or wiring the system.
Connecting or disconnecting the connectors.
Caution Failure to abide by the following precautions could lead to faulty operation of the
PC or the system, or could damage the PC or PC Units. Always heed these pre-
cautions.
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.
Interlock circuits, limit circuits, and similar safety measures in external circuits
(i.e., not in the Programmable Controller) must be provided by the customer.
Always use the power supply voltages 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.
