From the fire control room to the fire pump control cabinet, three lines start and feedback, one is public, and the fire pump control cabinet is four terminals. How can I connect it?

Answer:

Fire pump control cabinet is four terminals, a control terminal, a feedback terminal, control terminal and the feedback end of each pull a line connected to the public to do together, not a three line.
Two of the terminals are short together and are called common ends!
There are four connecting terminals in the fire control cabinet, one is the starting pump line, and the other is the feedback line. Then start the pump line and the public line, pump, common line and feedback line feedback.
