Supplementary explanation

Circuit II

Circuit I

Interpretation of symbols: 1QF indicates Circuit I breaker; 2QF indicates Circuit II breaker; 3QF indicates bus tie breaker; F indicates shunt strip; X indicates closed electromagnet.
Note: Box I, II and III contain the terminal numbers of the circuit breaker secondary circuit, those outside the box are the corresponding terminal numbers of the dual power bus coupler
controller, and those outside the box are the user connections.
Important reminder: To ensure the normal operation of dual power supply products and prevent operation errors, the dual power controller products need to be equipped with
corresponding mechanical interlock devices.

Note 1: The generator starting signal control terminals 37, 38
(normally closed) or 38, 39 (normally open) are wired by users
themselves;
Note 2: If the closing electrical interlock is required, an interlock
auxiliary switch shall be connected in series between the closing
output of the controller and the closing electromagnet of the circuit
breaker. The circuit on the dotted line is wired by the user.
