Application Precautions
5
• Always turn OFF the power supply to the CPU Unit, Slaves, and Commu-
nications Units before attempting any of the following. Not turning OFF
the power supply may result in malfunction or electric shock.
• Mounting or dismounting I/O Units, CPU Units, Memory Packs, or
Master Units.
• Assembling the Units.
• Setting DIP switches or rotary switches.
• Connecting cables or wiring the system.
!Caution
Failure to abide by the following precautions could lead to faulty operation of
the Ethernet Unit or the system, or could damage the Ethernet Unit. 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 cir-
cuits (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-cir-
cuiting in external wiring. Insufficient safety measures against short-cir-
cuiting may result in burning.
• Make sure that all the Backplane mounting screws, terminal block screws,
and cable connector screws are tightened to the torque specified in the
relevant manuals. Incorrect tightening torque may result in malfunction.
• Leave the label attached to the Unit when wiring to prevent wire clippings
from entering the Unit. Removing the label may result in malfunction if for-
eign matter enters the Unit.
• Remove the label after the completion of wiring to ensure proper heat dis-
sipation. Leaving the label attached 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 wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Wire all connections correctly.
• Mount Units only after checking terminal blocks and connectors com-
pletely.
• Make sure that the terminal blocks, expansion cables, and other items
with locking devices are locked in place.
• When transporting the Unit, use special packing boxes and protect it from
being exposed to excessive vibration or impacts during transportation.
