SAFETY INSTRUCTIONS
Design Precautions
Install a safety circuit external to the PLC that keeps the entire system
safe even when there are problems with the external power supply or
the PLC module. Otherwise, serious trouble could result from
erroneous output or erroneous operation.
-Outside the PLC, construct mechanical damage preventing interlock
circuits such as emergency stop, protective circuits, positioning upper
and lower limits switches and interlocking forward/reverse operation.
When the PLC detects the following problems, it will stop calculation and
turn off all output in the case of watchdog timer error, module interface
error, or other hardware errors.
However, one or more outputs could be turned on when there are
problems that the PLC CPU cannot detect, such as malfunction of output
device (relay, transistor, etc.) itself or I/O controller. Build a fail safe
circuit exterior to the PLC that will make sure the equipment operates
safely at such times. Also, build an external monitoring circuit that will
monitor any single outputs that could cause serious trouble.
Make sure all external load connected to output does NOT exceed the
rating of output module.
Overcurrent exceeding the rating of output module could cause fire, damage
or erroneous operation.
Build a circuit that turns on the external power supply when the PLC
main module power is turned on.
If the external power supply is turned on first, it could result in erroneous
output or erroneous operation.

SAFETY INSTRUCTIONS
Design Precautions
Installation Precautions
Do not bunch the control wires or communication cables with the main
circuit or power wires, or install them close to each other. They should
be installed 100mm (3.94inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
Use the PLC in an environment that meets the general specification
contained in this manual or datasheet.
Using the PLC in an environment outside the range of the general
specifications could result in electric shock, fire, erroneous operation, and
damage to or deterioration of the product.
Completely turn off the power supply before loading or unloading the
module.
Not doing so could result in electric shock or damage to the product.
Make sure all modules are loaded correctly and securely.
Not doing so could cause a malfunction, failure or drop.
Make sure I/O and extension connector are installed correctly.
Poor connection could cause an input or output failure.
When install the PLC in environment of much vibration, be sure to
insulate the PLC from direct vibration.
Not doing so could cause electric shock, fire, and erroneous operation.
Be sure to there are no foreign substances such as conductive debris
inside the module.
Conductive debris could cause fires, damage, or erroneous operation.

SAFETY INSTRUCTIONS
Wiring Precautions
Completely turn off the external power supply when installing or
placing wiring.
Not doing so could cause electric shock or damage to the product.
Make sure that all terminal covers are correctly attached.
Not attaching the terminal cover could result in electric shock.
Be sure that wiring is done correctly be checking the product’s rated
voltage and the terminal layout.
Incorrect wiring could result in fire, damage, or erroneous operation.
Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short circuits, fire, or
erroneous operation.
Be sure to ground the FG or LG terminal to the protective ground
conductor.
Not doing so could result in erroneous operation.
Be sure there are no foreign substances such as sawdust or wiring
debris inside the module.
Such debris could cause fire, damage, or erroneous operation.

SAFETY INSTRUCTIONS
Startup and Maintenance Precautions
Disposal Precaution
Do not touch the terminals while power is on.
Doing so could cause electric shock or erroneous operation.
Switch all phases of the external power supply off when cleaning the
module or retightening the terminal or module mounting screws.
Not doing so could result in electric shock or erroneous operation.
Do not charge, disassemble, heat, place in fire, short circuit, or solder
the battery.
Mishandling of battery can cause overheating or cracks which could result in
injury and fires.
Do not disassemble or modify the modules.
Doing so could cause trouble, erroneous operation, injury, or fire.
Switch all phases of the external power supply off before mounting or
removing the module.
Not doing so could cause failure or malfunction of the module.
Use a cellular phone or walky-talky more than 30cm (11.81 inch) away
from the PLC
Not doing so can cause a malfunction.
When disposing of this product, treat it as industrial waste.
Not doing so could cause poisonous pollution or explosion.
