Application Precautions
Observe the following precautions when using the PCU or the PC.
WARNING
Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
•
Always connect to a ground of 100
Ω
or less when installing the Units. Not con-
necting to a ground of 100
Ω
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 Power Supply Units, 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 may lead to faulty operation of the
PC, the PCU. or the system, or could damage the PC or PCU. 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.
•
Interlock circuits, limit circuits, and similar safety measures in external circuits
(i.e., not in the Programmable Controller) must be provided by the customer.
•
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.
•
Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in the relevant manuals. Incorrect
tightening torque may result in malfunction.
•
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 in places where the power supply is unsta-
ble. An incorrect power supply 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.
•
Leave the label attached to the Unit when wiring. Removing the label may re-
sult in malfunction if foreign matter enters the Unit.
•
Remove the label after the completion of wiring to ensure proper heat dissipa-
tion. Leaving the label attached may result in malfunction.
