straight line wire drawing machine technical lThe first Safety precautions 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.
