Application Precautions
5
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied in places where the power supply
is unstable. An incorrect power supply 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.
• Disconnect the LG (line ground) terminal and GR (ground) terminal before
performing withstand voltage and insulation resistance tests.
• Confirm that set parameters and data operate properly.
• Perform wiring according to specified procedures.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in 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 setting the Startup
Mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• After replacing Units, resume operation only after transferring to the new
CPU Unit, Special I/O Units, CPU Bus Units, and externally connected
devices the contents of the DM Area, Holding Area, and other data
required for resuming operation. Not doing so may result in an unex-
pected operation.
• 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.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunc-
tion or damage.
• Never turn OFF the power to the Unit while transferring data.
