Safety Instruction
Safety Instructions for design process
Please install a protection circuit on the exterior of PLC so that the whole system may
operate safely regardless of failures from external power or PLC. Any abnormal output or
operation from PLC may cause serious problems to safety in whole system.
- Install protection units on the exterior of PLC like an interlock circuit that deals with opposite
operations such as emergency stop, protection circuit, and forward/reverse rotation or install an
interlock circuit that deals with high/low limit under its position controls.
- If any system error (watch-dog timer error, module installation error, etc.) is detected during
CPU operation in PLC, all output signals are designed to be turned off and stopped for safety.
However, there are cases when output signals remain active due to device failures in Relay and
TR which can’t be detected. Thus, you are recommended to install an addition circuit to monitor
the output status for those critical outputs which may cause significant problems.
Never overload more than rated current of output module nor allow to have a short circuit.
Over current for a long period time may cause a fire .
Never let the external power of the output circuit to be on earlier than PLC power, which may
cause accidents from abnormal output or operation.
Please install interlock circuits in the sequence program for safe operations in the system
when exchange data with PLC or modify operation modes using a computer or other
external equipments
Read specific instructions thoroughly when conducting control operations
with PLC.

Safety Instructions on installation process
I/O signal or communication line shall be wired at least 100mm away from a high-voltage
cable or power line.Fail to follow this
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 may be caused.
Before install or remove the module, be sure PLC power is off. If not, electric shock or damage
on the product may be caused.
Be sure that every module is securely attached after adding a module or an extension
connector.If the product is installed loosely or incorrectly, abnormal operation, error or dropping
may be caused. In add
ition, contact failures under poor cable installation will be causing
malfunctions as well.
Be sure that screws get tighten securely under vibrating environments. Fail to do so will put
the product under direct vibrations which will cause electric shock, fire and abnormal operation.
Do not come in contact with conducting parts in each module, which may cause electric
shock, malfunctions or abnormal operation.

Safety Instructions for wiring process
Prior to wiring works, make sure that every power is turned off. If not, electric shock or
damage on the product may be caused.
After wiring process is done, make sure that terminal covers are installed properlybefore
its use.Fail to install the cover may cause electric shocks.
Warning
Check rated voltages and terminal arrangements in each product prior to its wiring
process.Applying incorrect voltages other than rated voltages and misarrangement among
terminals may cause fire or malfunctions.
Secure terminal screws tightly applying with specified torque.If the screws get loose, short
circuit, fire or abnormal operation may be caused.
Securing screws too tightly will cause
damages to the module or malfunctions, short circuit, and dropping.
Be sure to earth to the ground using Class 3 wires for FG terminals which is exclusively
used for PLC. If the terminals not grounded correctly, abnormal operation or electric shock
may be caused.
Don’t let any foreign materials such as wiring waste inside the module while wiring,
which may causefire, damage on the product or abnormal operation.
Make sure that pressed terminals get tighten following the specified torque. External
connector type shall be pressed or soldered using proper equipments.
Caution

Safety Instruction
Safety Instructions for test-operation and maintenance
Don’t touch the terminal when powered. 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.
Don’t let the battery recharged, disassembled, heated, short or soldered. Heat, explosion
or ignition may cause injuries or fire.
Warning
Do not make modifications or disassemble each 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 equipment such as walkie-talkie or cell phones at least 30cm away
from PLC. If not, abnormal operation maybe caused.
When making a modification on programs or using run to modify functions under PLC
operations, read and comprehend all contents in the manual fully. Mismanagement will
cause damages to products and accidents.
Avoid any physical impact to the battery and prevent it from dropping as well. Damages
to battery may cause leakage from its fluid. When battery was dropped or exposed under strong
impact, never reuse the bat
tery again. Moreover skilled workers are needed when exchanging
batteries.

1.2 Cautions for Selecting Module
It describes the cautions when selecting digital I/O modules.
1) There are two digital input types; current sink input and current source input
Since the wiring method of external input power varies in a DC input module, it should be selected considering the
specifications of input connectors.
2) The max. simultaneous input point varies depending on a module type. That is, it may be different, depending on input
voltage and ambient temperature. Please review the specifications of input module to apply before use.
3) In case of an application for highly frequent switching or inductive load switching, the relay output module may have a
shorter life, so it needs a transistor module or triac output module, instead of it.
4) If an output module operates an inductive load(L), the max. On/Off frequency should be limited to On per 1 second and
Off per 1 second, each.
5) In case a counter timer using DC/DC converter is used as a load in an output module, setting the average current may
cause a trouble because it may have inrush current in case of On or a certain cycle during operation. Therefore, if using the
foresaid load, it is necessary to connect resistance or inductor parallel to load or alternatively use a module of which max.
load current is large.

7)Aclamped terminal with sleeve can not be used for the terminal strip. The clamped terminals suitable for terminal strip
are as follows(JOR 1.25-3:Daedong Electricity).
8) The cable size connected to a terminal strip should be 0.3~0.75 ㎟stranded cable and 2.8 ㎜thick. The cable may have
different current allowance depending on the insulation thickness.
9) The coupling torque available for fixation screw and terminal strip screw should follow the table below.
