supplying this device is turned on.
DANGER
!
Hazardous voltage.
Can cause personal injury and
equipment damage.
Neutral Sensor terminals must be properly
connected or shorted together before
energizing the circuit.
B. GROUND FAULT RESIDUAL METHOD - 3 Phase / 4 Wire
For circuit breakers with "G", "V" or "W" in the catalog number. Reference page 2/10.
1. Set all trip unit settings to their maximum setting and on model 586 trip units set GF TYPE = GND RESIDUAL
2. Connect the supplied neutral sensor wires exiting the breaker to the proper neutral sensor per Table 1.
3. Using Figure 2, connect a low voltage current source thru the neutral sensor.
4. Close the circuit breaker.
5. Apply a test current equal to 125 percent of the ground fault pickup setting for a maximum of 10 seconds.
6. Turn off the low voltage current source.
7. Verify that the circuit breaker tripped and record the results. Proceed to step 8, if tripped, otherwise contact technical support:

www.usa.siemens.com/powerdistribution
8. Repeat steps 3– 7 with the low voltage current source connected to circuit breaker phases A, B and C as shown in Figure 1.
9. Testing is completed. Turn off the low voltage current source and disconnect from circuit breaker.
For circuit breakers with "K" in the catalog number. Reference page 2/10.
1. Set the GF ALARM SETTING to the minimum setting and GF TYPE = GND RESIDUAL. Set all other trip unit settings to their maximum setting.
2. Connect the supplied neutral sensor wires exiting the breaker to the proper neutral sensor per Table 1.
3. Using Figure 2, connect a low voltage current source thru the neutral sensor.
4. Close the circuit breaker.
5. Apply a test current equal to 125 percent of the GF ALARM SETTING.
6. While the test current is on, verify the trip unit LCD screen shows GROUND FAULT ALARM.
7. Turn off the low voltage current source.
8. If ground fault alarm indication was displayed, record the results and proceed to step 9, otherwise contact technical support.
9. Repeat steps 3 – 8 with the low voltage current source connected to circuit breaker phases A, B and C as shown in Figure 1.
10.Testing is completed. Turn off the low voltage current source and disconnect from circuit breaker.
