7.3.3 Source 1 to Source 2 Bypass (Open Transition Only)

The Source 1 switch can be isolated and bypassed by the follow- ing sequence:

1.Move the generator selector switch to the RUN position because the load needs to be energized from the Source 2 power source.

2.Make sure that the Source 2 power source is available.

3.Open the source/switching device.

4.Close the Source 2 bypass switching device manually. The Source 2 bypass light will be illuminated.

5.Rack out the Source 1 switching device (see Section 6). The Source 1 isolated light will illuminate.

6.Inspect and/or perform the needed maintenance on the Source 1 switching device.

7.Rack in the Source 1 switching device (see Section 6). The Source 1 switching device will automatically recharge when it is in the CONNECT position. The Source 1 isolated light will no longer be illuminated.

8.Open the Source 2 bypass switching device. The Source 2 bypass light will no longer be illuminated.

9.The Source 1 switching device is now back in automatic oper- ation.

7.3.4 Source 2 to Source 1 Bypass (Open Transition Only)

The Source 2 switching device can be bypassed and isolated by the following sequence:

1.Ensure that the Source 1 power is available since the load will be energized from the Source 1 power source.

2.Move the generator selector switch to the OFF position to avoid nuisance starting of the generator while work is being performed on the Source 2 switching device.

3.Open the Source 2 switching device.

4.Close the Source 1 bypass switching device manually. The Source 1 bypass light will illuminate.

5.Rack out the Source 2 switching device (see Section 6). The Source 2 isolated light will illuminate.

6.Inspect and/or perform the needed maintenance on the Source 2 switching device.

7.Rack in the Source 2 switching device (see Section 6). The Source 2 isolated light will no longer be illuminated.

8.Open the Source 1 bypass switching device. The Source 1 light will no longer be illuminated.

9.The switching device is now back in automatic operation.
