Safety Instructions for design process
Please install a protection circuit on the exterior of PLC so that the
whole system mayoperate safelyregardless of failures from
external power or PLC. Any abnormal output or operation from PLC may cause serious problems
to safetyin whole system.
- Install protection units on the exterior of PLC like an interlock circuit that deals with opposite
operations such as emergencystop,protection circuit, and forward/reverse rotation or install an
interlock circuit that deals with high/lowlimitunder itspositioncontrols.
- 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
theoutputstatusfor thosecriticaloutputs whichmaycause significant problems.
Never overload more than rated current of output module nor
allow to have a short circuit.Overcurrentforalongperiodtimemay
cause a fire.
Never let the external power of the output circuit to be on earlier
than PLC power, which maycauseaccidentsfrom abnormaloutputor
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 for design process
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 instruction maycause malfunctionsfrom noise
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 maybe caused.
Before install or remove the module, be sure PLC power is off. If not, electric shock or damage
on theproduct maybe 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 addition, contact failures under poor cable installation will be causing
malfunctions aswell.
Be sure that screws get tighten securely under vibrating environments. Fail to do so will put
the product underdirect vibrations which will cause electric shock, fire andabnormal operation.
Do not come in contact with conducting parts in each module, which may cause electric
shock,malfunctionsorabnormal operation.
Caution

Safety Instructions for wiring process
Prior to wiring works, make sure that every power is turned off. If not, electric shock or damage
on theproduct maybe caused.
After wiring process is done, make sure that terminal covers are installed properly before its
use.Failtoinstallthecovermaycauseelectricshocks.
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
terminalsmaycausefire ormalfunctions.
Secure terminal screws tightly applying with specified torque. If the screws get loose, short
circuit,fireorabnormal operation may be caused.Securing screws too tightly will cause damages to
themoduleormalfunctions, shortcircuit,anddropping.
*
Be sure to earth to the ground using Class 3 wires for FG terminals which is exclusively
used for PLC. If the terminals notgrounded 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
maycause fire, damageon the product orabnormaloperation.
Make sure that pressed terminals get tighten following the specified torque. External
connector type shall be pressedor soldered using proper equipments.
Caution

Safety Instruction

Safety Instructions for test-operation and maintenance
Don’t touch the terminal when powered.Electricshockorabnormaloperation mayoccur.
Prior to cleaning or tightening the terminal screws, let all the external power off including
PLC power. If not, electric shock or abnormaloperation mayoccur.
Don’t let the battery recharged, disassembled, heated, short or soldered. Heat, explosion or
ignition maycause injuriesorfire.
Warning
Do not make modifications or disassemble each module. Fire, electric shock or abnormal
operation mayoccur.
Prior to installing or disassembling the module, let all the external power off including PLC
power. If not, electric shock or abnormal operation mayoccur.
Keep any wireless equipment such as walkie-talkie or cell phones at least 30cm away from
PLC. If not,abnormal operation maybecaused.
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 productsandaccidents.
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 battery again. Moreover skilled workers are needed when exchanging
batteries.
