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 troubleshooting

1. Automatic transfer switch does not move when connected to the power, and the controller light is not on.

Possible causes:
1. Whether the installation wiring is correct and tight;
2. Whether the fuse is blown.
Troubleshooting:
1. Check whether the circuit breaker's incoming end is loose and the wiring fails. If there is any disconnection, reconnect it.
2. For 3-pole ATS, the neutral line should be connected to the neutral terminal.
3. Replace the fuse.

2. The controller power light flashes.

Possible causes:
1. Power failures: power overvoltage; poor power line contact; controller failure.
2. Power light blinks, buzzer alarm.
Troubleshooting:
1. Readjust the incoming line and supply voltage.
2. Check whether the incoming power supply has a loss of phase, or a loose connection.
3. Insert the controller plug again or replace the controller.
4. The neutral line and phase line of the power supply are connected reversely and reconnect it correctly again.
