Installation
 ◆ Installation must be carried out by the specialists who have received the necessary electrical 
training and understood enough electrical knowledge.
 ◆ Disconnect all external power supplies of the system before removing/installing the module. 
Failure to do so may result in electric shock, module fault or malfunction.
 ◆ Do not use the PLC where there are dust, oil smoke, conductive dust, corrosive or combustible 
gases, or exposed to high temperature, condensation, wind & rain, or subject to vibration and 
impact. Electric shock, re and malfunction may also result in damage or deterioration to the 
product.
 ◆ The PLC is open-type equipment that must be installed in a control cabinet with lock (cabinet 
housing protection > IP20). Only the personnel who have received the necessary electrical 
training and understood enough electrical knowledge can open the cabinet.
 ◆ Prevent metal lings and wire ends from dropping into ventilation holes of the PLC during 
installation. Failure to comply may result in re, fault and malfunction.
 ◆ Ensure there are no foreign matters on ventilation surface. Failure to comply may result in poor 
ventilation, which may cause re, fault and malfunction.
 ◆ Ensure the module is connected to the respective connector securely and hook the module 
rmly. Improper installation may result in malfunction, fault or fall-o.
Wiring
 ◆ Wiring must be carried out by personnel who have received the necessary electrical training 
and understood enough electrical knowledge.
 ◆ Disconnect all external power supplies of the system before wiring. Failure to comply may 
result in electric shock, module fault or malfunction.
 ◆ Install the terminal cover attached to the product before power-on or operation after wiring is 
completed. Failure to comply may result in electric shock.
 ◆ Perform good insulation on terminals so that insulation distance between cables will not 
reduce after cables are connected to terminals. Failure to comply may result in electric shock or 
damage to the equipment.
