OPERATION  

 

Safety  

Before  operating  the  equipment,  check  that  the  Protective  Earth  is  properly 
connected. 

 

Check out the electrical installation in both sides (input and output) of the cabinet. 
All wires shall be connected and secured before proceeding to the power supply 
start-up. 

 

State Machine 

The operation of the power supply is based on 6 different states (rectangles) and 6 transitions 
(rhombus). Each state defines the behaviour and possible actions of the power supply:
