A.The input power supply is three-phase 380V50HZ. The voltage waveform is sinusoidal, and the amplitude fluctuation is not greater than+5~- 10%. The frequency fluctuation shall not be greater than 2HZ, and each phase shall be symmetrical. There are no higher harmonics in the power grid that are sufficient to damage the frequency converter. B. Temperature: 0~40 ℃ C.Humidity: The relative humidity shall not exceed 85% (20 ℃±5 ℃),D. Altitude: less than 1000 meters E. No severe vibration and impact
LZ600 wire drawing machine
1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.
1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.
1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.
1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.
1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.
1. 6 Before starting the machine, check whether the safety device is normal.
1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.
1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.
1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.
The second Delivery inspection
2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.
2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.
2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use.

The "7+3" industry is the direction and focus of Sichuan's industrial development in the near future. Therefore, the plan focuses on the long-term development of the industry. We will strive to increase the added value of the “7+3†industrial industry to 238 billion yuan by 2020, accounting for more than 90% of the industrial added value of the province's above-scale industries. We will establish more than 60 state-level enterprise technology centers with a new product output rate of 30%. Gradually formed into the Mangle Guangyu Electronic Information Industry Belt, the Chengde-owned Capital Equipment Equipment Manufacturing Industry Belt, the Chengde Miannan-funded Automobile Industry Belt, the Panxi Vanadium-titanium-Rare Earth Industrial Belt, the Chengle-Mao Yamian Silicon Industry Belt, and the Southern Sichuan Province. The industrial belts along the Yangtze River, the chemical industry belt in the northeastern Sichuan, the natural gas chemical industry belt in the northeastern Sichuan, and the textile and apparel footwear industry belt in Chengdu have become the most competitive modern manufacturing bases in the central and western regions.
The objective of the “Eight Industrial Adjustment and Revitalization Action Plan†is to take the lead in boosting the eight major industries of equipment manufacturing, vanadium-titanium steel, automotive, petrochemical, textile, light industry, non-ferrous metals, and electronic information, so that it can quickly emerge from the financial crisis and lead it. The province's industry seizes market opportunities. It is expected that by 2011, the eight major industries will realize sales revenue of 190.8 billion yuan, an average annual increase of 20%, and the industrial added value will be 668 billion yuan, an average annual increase of 20.3%. To this end, in the next three years, 8 major industries will implement 1,376 key projects with a total investment of 415.9 billion yuan.
In terms of structure, the “7+3†industry development plan lays emphasis on guidance. While proposing development goals and priorities, it also clarifies policy support and corresponding coordination mechanisms; the 8 major industrial adjustment and revitalization action plans emphasize operability more specifically. The targets, priorities, and policies also define the backbone enterprises and specific projects. In addition, the plan also clarifies each project's annual implementation goals one by one.
At present, the Sichuan Economic Commission is preparing specific annual plans in accordance with the requirements of the plans and action plans. The eight major industry adjustment and revitalization action plans for 2009 have been completed.
The Secret Government of Sichuan Provincial Government has recently issued the “7+3†Industrial Development Plan (2008-2020) and the “Eight Industrial Adjustment and Revitalization Action Plan (2009-2011)â€.
