Wiring Diagram

* The above wiring diagram is just for your reference. With the different types and functions, the wiring is also different.
* When the fire takes place, EPS signal is on (provided by firefighting center) and the circuit breakers Q1 & Q2 is released or cut off.
* Q1 & Q2 refer to circuit breakers.
* KG refers to the wiring terminals.
* The R & N power ON indicator lamps are external (provided by users).
* The dashed part is supplied by users.

* 3P refers to 3-pole circuit breaker and 4P means 4-pole circuit breaker.
* 24VDC (external) is supplied by the fire control center.

Tips: Automatic transfer switch trips but the light is on, how to do?

Possible causes:

Transportation causes the tripping of ATS circuit breakers.
In the usage, the ATS circuit breaker trips.

Troubleshooting:

If it is caused by transportation, reconnect the molded case circuit breaker by hand, and then changeover to automatic position meanwhile press the reset key.
If the tripping is caused in the use, first check the load conditions of circuit breaker.

If tripping is the cause by short circuit, first troubleshoot the short circuit and then transfer switch manually or automatically. During the troubleshooting of short-circuit fault, manual or automatic changeover is not allowed, which may cause secondary short circuit or personal injury.
In the case of tripping under overload conditions, first check the load of the electrical equipment, and check whether the rated current of the molded case circuit breaker of the ATS can meet the load. If not, replace the molded case circuit breaker as much as possible. Otherwise, the circuit breaker will frequently trip, which causes burnout of the circuit breaker static and movable contacts and affects the power supply system.
