Application Precautions
5
• Separate the line ground terminal (LG) from the functional ground termi-
nal (GR) on the Power Supply Unit before performing withstand voltage
tests or insulation resistance tests. Not doing so may result in burning.
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
• With CS-series PLCs, be sure that all the Unit and Backplane mounting
screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• Be sure that all terminal screws, and cable connector screws are tight-
ened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign 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.
• Wire all connections correctly.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Mount Units only after checking terminal blocks and connectors com-
pletely.
• Be sure that the terminal blocks, Memory Units, expansion cables, and
other items with locking devices are properly locked into place. Improper
locking may result in malfunction.
• Check switch settings, the contents of the DM Area, and other prepara-
tions before starting operation. Starting operation without the proper set-
tings or data may result in an unexpected operation.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected opera-
tion.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PLC (including the setting of the
startup operating mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so
may break the cables.
• Do not use commercially available RS-232C personal computer cables.
Always use the special cables listed in this manual or make cables
according to manual specifications. Using commercially available cables
may damage the external devices or CPU Unit.
• Never connect pin 6 (5-V power supply) on the RS-232C port on the CPU
Unit to any device other than an NT-AL001 or CJ1W-CIF11 Adapter.The
external device or the CPU Unit may be damaged.
