Safety Instruction
Before using the product …
For your safety and effective operation, please read the safety instructions
thoroughly before using the product.
► Safety Instructions should always be observed in order to prevent accident
or risk with the safe and proper use the product.
► Instructions are separated into “Warning” and “Caution”, and the meaning of
the terms is as follows;
This symbol indicates the possibility of serious injury
or death if some applicable instruction is violated
This symbol indicates the possibility of slight injury
or damage to products if some applicable instruction
is violated
► The marks displayed on the product and in the user’s manual have the
following meanings.

► The user’s manual shall be kept available and accessible to any user of the
product.
Warning
Caution

Safety Instruction
Safety Instructions when designing
 Please, install protection circuit on the exterior of PLC to protect
the whole control system from any error in external power or PLC
module. Any abnormal output or operation may cause serious problem
in safety of the whole system.
- Install applicable protection unit on the exterior of PLC to protect
the system from physical damage such as emergent stop switch,
protection circuit, the upper/lowest limit switch, forward/reverse
operation interlock circuit, etc.
- If any system error (watch-dog timer error, module installation error,
etc.) is detected during CPU operation in PLC, the whole output is
designed to be turned off and stopped for system safety. However,
in case CPU error if caused on output device itself such as relay or
TR can not be detected, the output may be kept on, which may
cause serious problems. Thus, you are recommended to install an
addition circuit to monitor the output status.
 Never connect the overload than rated to the output module nor
allow the output circuit to have a short circuit, which may cause a
fire.
Never let the external power of the output circuit be designed to
be On earlier than PLC power, which may cause abnormal output or
operation.
 In case of data exchange between computer or other external
equipment and PLC through communication or any operation of
PLC (e.g. operation mode change), please install interlock in the
sequence program to protect the system from any error. If not, it
may cause abnormal output or operation.
Warning

Safety Instruction
Safety Instructions when designing
Safety Instructions when designing
 I/O signal or communication line shall be wired at least 100mm
away from a high-voltage cable or power line. If not, it may cause
abnormal output or operation.
Caution
 Use PLC only in the environment specified in PLC manual or
general standard of data sheet. If not, electric shock, fire, abnormal
operation of the product or flames may be caused.
Before installing the module, be sure PLC power is off. If not,
electric shock or damage on the product may be caused.
 Make sure that each module of PLC is correctly secured. If the
product is installed loosely or incorrectly, abnormal operation, error or
dropping may be caused.
Make sure that I/O or extension connecter is correctly secured. If
not, electric shock, fire or abnormal operation may be caused.
If lots of vibration is expected in the installation environment,
don’t let PLC directly vibrated. Electric shock, fire or abnormal
operation may be caused.
Avoid any foreign metallic materials contamination inside the
product, which may cause electric shock, fire or abnormal
operation..
Caution

Safety Instruction
Safety Instructions when wiring
Prior to wiring, make sure that power of PLC and external power is
turned off. If not, electric shock or damage on the product may be
caused.
Before PLC system is powered on, make sure that all the covers
of the terminal are securely closed. If not, electric shock may be
caused
Warning
 Install wires correctly after checking the voltage rated of each
product and the arrangement of terminals. If not, fire, electric shock
or abnormal operation may be caused.
Secure the screws of terminals tightly with specified torque when
wiring. If the screws of terminals get loose, short circuit, fire or abnormal
operation may be caused.
*
Make sure to use the ground wire of Class 3 for FG terminals,
which is exclusively used for PLC. If the terminals not grounded
correctly, abnormal operation may be caused.
Avoid any foreign materials such as wiring waste inside the
module while wiring, which may cause fire, damage on the product
or abnormal operation.
Caution

Safety Instruction
Safety Instructions for test-operation or repair
Safety Instructions for waste disposal
 Do not touch the terminal when powered on. Electric shock or
abnormal operation may occur.
Prior to cleaning or tightening the terminal screws, let all the
external power off including PLC power. If not, electric shock or
abnormal operation may occur.
 Do not recharge, disassemble, heat, short or solder the battery.
Heat, explosion or ignition may cause injuries or fire.
Warning
 Do not remove PCB from the module case nor remodel the
module. Fire, electric shock or abnormal operation may occur.
 Prior to installing or disassembling the module, let all the external
power off including PLC power. If not, electric shock or abnormal
operation may occur.
Keep any wireless installations or cell phone at least 30cm away
from PLC. If not, abnormal operation may be caused.
Caution
 Product or battery waste shall be processed as industrial waste.
The waste may discharge toxic materials or explode itself.
