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 is supplied. Be particularly careful in places where the
power supply is unstable. An incorrect power supply may result in mal-
function.
• 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.
• 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 all the mounting screws, terminal screws, and cable connec-
tor screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• When wiring the CPM2B, take countermeasures to prevent wiring cuttings
from coming into contact with the product, such as covering the whole
product with a dustproof cover. If wiring cuttings adhere to the PCB or cir-
cuit elements they may cause short-circuiting.
• Be sure to perform wiring in accordance with the relevant operation man-
ual. Incorrect wiring may result in burning.
• Double-check all the wiring before turning ON the power supply. Incorrect
wiring may result in burning.
• Be sure that the terminal blocks, expansion cables, and other items with
locking devices are properly locked into place. Improper locking may
result in malfunction.
• Be sure that terminal blocks and connectors are connected in the speci-
fied direction with the correct polarity. Not doing so may result in malfunc-
tion.
• Check the user program for proper execution before actually running it on
the PLC. 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.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Resume operation only after transferring to the new CPU board the con-
tents of the DM and HR Areas required for resuming operation. Not doing
so may result in an unexpected 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. Doing so may break the cables.
• Under no circumstances should batteries be short-circuited between pos-
itive (+) and negative (
−
) terminals, charged, disassembled, heated, or
thrown into fire.
• 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.
