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.
