The fixed switching device frame has two mounting feet, one on each side, to permit the fixed switching device to be securely mounted. Each mounting foot has two slotted mounting holes which are used to bolt the switching device securely in place. Use either 3/8” or M 10 bolts for this purpose. Refer to the dimen- sional drawings supplied with the transfer switch for switching device and bus stab dimensions.

6.3 Switching Device Operation

Switching devices should be operated manually and/or electrically before they are put into service. This can be done during the installation process or some later date prior to start-up. To check the switching device operation, follow the operational procedures outlined in switching device manual supplied with the transfer switch for both manually operated and electrically operated switching devices.

Section 7: Operation of the Bypass Isolation Transfer Switch

7.1 Operator Panel

The design of this transfer switch allows quick removal of the dif- ferent switching devices for inspection or maintenance or, if required, quick replacement.

The bypass isolation switch has two operator panels with switches and lights (Figure 35). The following descriptions are for those features that are standard with the bypass isolation switch. Additional features are described in the options section.

Figure 35.Bypass Isolation Switch.

The left door control panel has the following standard features:

1.Light to indicate if the Source 1 power source is available.

2.Light to indicate if the Source 2 power source is available.

3.Light to indicate if the Source 1position is energized, that is, the Source 1 switching device in the automatic transfer switch is closed.

4.Light to indicate if the Source 2 position is energized, that is, the Source 2 switching device in the automatic transfer switch is closed.

5.The Push-To-Test button allows testing of the transfer switch. Pushing the button two times will simulate a power failure, causing the transfer switch to start the transfer sequence. Pressing the button again will restore regular power.

Three-position selector switch to control the generator:

•AUTO - The intelligence circuit of the transfer switch will start the generator if the Source 1 power source is not available.

•OFF - The intelligence circuit of the transfer switch will not be able to start the generator, which eliminates nuisance starts during maintenance.

•RUN - The generator will run regardless of the availability of the Source 1 power source.
