Application Precautions
5
• 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 burn-
ing.
• 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 the con-
tents 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.
• Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent malfunction due to static electricity.
• Do not turn OFF the power supply to the Unit while data is being trans-
ferred.
• When transporting or storing the product, cover the PCBs with electrically
conductive materials to prevent LSIs and ICs from being damaged by
static electricity, and also keep the product within the specified storage
temperature range.
• Do not touch the mounted parts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.
• Double-check the pin numbers when assembling and wiring the connec-
tors.
• Wire correctly according to specified procedures.
• Do not connect pin 6 (+5V) on the RS-232C Option Board (CP1W-CIF01)
on the CPU Unit to any external device other than the NT-AL001 or
CP1W-CIF11 Conversion Adapter. The external device and the CPU Unit
may be damaged.
