When connecting high-speed presses the power problems that need attention

    When connecting the high-speed presses the power first consideration to the employee's own security, then the power if an error occurs may cause damage to internal wiring high-speed presses, large and small, in order to avoid problems that occur when you connect. Please carefully read this article.
     
High-speed presses special attention before installation Power matters:
The correct power connection:
 
(1), high-speed punch power supply wiring methods:
    ① measured by detecting electrical multimeter pen or a non-voltage line (N line) high-speed punch control box connected to the power supply terminal S side and the other two lines can be arbitrarily connected to A, B, C three terminals.
 
    ② If the opposite direction of the motor, then any phase of the two lines to be reversed, with the N line must not be reversed.
 
(2), high-speed precision punch the wrong wiring will lead to the solenoid valve (SV) malfunction, resulting in personnel, equipment are at risk, ask the customer to pay special attention to checking.
 
(3), high-speed presses Note: If the event of failure to control the electrical fittings, PE line was grounded condition, the fuse burned, may contribute to the protective effect.
 
(4), the way high-speed presses and power connections to note: First, open air of concern to "OFF" position, then the power switch on the operation panel open concern in the "OFF" position, the control panel and power supply cut off, view the fuse did not After the break, according to the power of high-speed presses specifications and main motor power, according to the following table and electrical equipment based on the provisions of the power supply is connected to a control panel the connection terminals.
