●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, fire 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 filings and wire ends from dropping into ventilation holes of the PLC
during installation. Failure to comply may result in fire, fault and malfunction.
●Ensure there are no foreign matters on ventilation surface. Failure to comply may result
in poor ventilation, which may cause fire, fault and malfunction.
●Ensure the module is connected to the respective connector securely and hook the
module firmly. Improper installation may result in malfunction, fault or fall‑off.
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.
●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.
