The "Caution, Notice, Warning, Danger" symbols in this manual do not represent all the safety points to be observed, and are only used as a supplement to various operation safety points. Therefore, the installation and operation personnel must be strictly trained and master the correct operations and all the safety points before actual operation. When operating Emerson PLC products, the safety rules in the industry, the general safety points and special safety instructions specified in this manual must be strictly observed. These notices are highlighted in the manual by a warning triangle and are marked as follows according to the level of danger: Danger: indicates that death, severe personal injury, or substantial property damage will result if proper precautions are not taken. Warning: indicates that death, severe personal injury, or substantial property damage could possibly result if proper precautions are not taken. Caution: indicates that minor personal injury or property damage can result if proper precautions are not taken. Notes for designing The programming must include safety circuit to ensure the safe application of the PLC (Programmable Logic Controller) system upon power off or the PLC malfunction. Note the following when programming: z The external circuit of the PLC must include the emergency braking circuit, protection circuit, mutual interlock circuit of forward/reverse rotation, and the interlock switch of position upper/lower limit for preventing equipment from damage. z For the safe operation of the equipment and output signals of the serious accident, please design the external protection circuit and the safety mechanism. z All the outputs may be shutdown when the CPU of the PLC detects the abnormity of the system; the failure of part PLC circuit may result in uncontrolled PLC output. A suitable external control circuit must be designed to ensure the normal operation of the equipment. z When the PLC output unit such as the relay or the transistor is damaged, the PLC output cannot be controlled as ON or OFF state. z The PLC is designed to be used in the electrical environment of indoor area B and C ☆ . However, to prevent the high lightning voltage from damaging the equipment through the ports of power input, signal input or control output, a SPD should be installed in the power supply system. ☆: According to IEC61131-2, section 8.3.1 classification declaration Notes for installation z Units should not be installed in areas subject to the following conditions: excessive or conductive dust, corrosive or flammable gas, moisture or rain, excessive heat, regular impact shocks or excessive vibration. Electric shock, fire hazard and mishandling may also damage the product. z Take special care not to allow metal debris and wire lead to fall inside the vent of the PLC during the screw hole processing and wiring. Otherwise there is a danger of fire, damage or faulty operation of equipment. z Once the installation of the new PLC is complete, remove everything on the surface of the vent, including packing goods such as protective paper. Otherwise the poor ventilation during the operation may result in fire, damage or faulty operation of equipment. z Do not wire, inset or pull out the cable plug with power applied. Otherwise there is a danger of electric shock or circuit damage. z Installation and wiring must be fastening and reliable. Bad contact may result in faulty operation of equipment. z The input/output cable of high frequency signal should use the shielding cable to improve the interference rejection of the system. Notes for wiring z Installation and wiring can be done only after the external power supplies are all disconnected. Otherwise there is a danger of electric shock or equipment damage. z Once the installation and wiring of the PLC is complete, cleanup the spot at once. To prevent the electric shock, replace the port cover of the product before power is on. z When wiring AC supplies, the ‘Live’ cable should be connected to the ‘L’ terminal and the ‘Neutral’ cable should be connected to the ‘N’ terminal. Otherwise the PLC will be damaged. z Don’t power +24V port of the main module by the external power supply. Otherwise the PLC will be damaged. z Do not lay I/O signal cables of the PLC next to other power cables or strong interference circuits. z Do not make the earth port (PG) of the main module and the heavy current power system share the same earthing. Notes for operation and maintenance z Do not touch the ports when the power is applied, otherwise there is a danger of an electric shock or faulty operation of equipment. z The cleaning and the fastening work can be done only after the power supply has been disconnected; otherwise there is a danger of electric shock. z Only after the power supply has been disconnected, can the communication signal cables and the cables of the expansion module or control unit be connected or removed. Otherwise there is a danger of equipment damage or faulty operation of equipment. z Do not disassemble the PLC. Otherwise it may destroy the inner electrical components. z Read through this manual carefully before operating the PLC. Safe and efficient operation of the product, such as program alternation, trial operation, start and stop, is only based on correct operation and maintenance. z Do not replace the button cell battery with power applied. If the battery replacement is indeed to be done with power applied, it shall always be carried out by adequately trained electric technical personnel wearing insulated gloves. Notes for the product disposal Note the following when disposing the PLC: z Explosive of the electrolytic capacity: The capacities on the circuit board may explode when burning. z Exhaust gas when burning: The main body of the PLC is plastic, and it may produce poisonous gas when burning. z Disposal of button cell battery: Classified collecting and disposing, and separating from the daily-life rubbish. Follow the local environmental regulations to dispose the PLC or dispose it as industrial waste.
