Application Precautions 5
• 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.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction.
• 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.
• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.
• Be sure that the terminal blocks, connectors, Option Boards, and other
items with locking devices are properly locked into place. Improper locking
may result in malfunction.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Wire correctly and double-check all the wiring or the setting switches before
turning ON the power supply. Incorrect wiring may result in burning.
• Check that the DIP switches and data memory (DM) are properly set
before starting 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.
• Resume operation only after transferring to the new CPU Unit and/or Spe-
cial I/O Units the contents of the DM, HR, and CNT Areas required for
resuming operation. Not doing so may result in an unexpected operation.
• 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. Doing so may break the cables.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• Before touching the Unit, be sure to first touch a grounded metallic object
in order to discharge any static buildup. Not doing so may result in mal-
function or damage.
• Install the Unit properly as specified in the operation manual. Improper
installation of the Unit may result in malfunction.
