Remote Emergency Stop Push button ES1, ES2...ES10 are wired by using separate 4 core cable from each ES to the MCC (motor control unit). Inside the MCC all those ESs are serially connected by putting jumper between the corresponding terminals.
This is commonly practice in the industry but I could not find a any international standard for this type of wiring.
1. Please help me to find the reference electrical or safety standard for the above mentioned system
2. Can the remote ES1 and ES2 serially connected at the ES1 push button without wiring towards MCC?
Since my client does not like the ASi Safe Estop system. Only they want is Hardwired Estop.
