Note: If you use a blower, debris could get stuck in the switch.
- Verify that all cable connections are correct.
- Use a phase rotation meter in order to verify that the phase rotation of both power sources match.
- Check the engine start contacts and verify that the connection of all control wires are correct.
- Check the settings of the timers. If necessary, adjust the timers. If necessary, adjust any optional accessories. See Service Information, "Timers" for information on setting the timers.
- Verify the actual torque values of the lugs in order to check the integrity of the power connections. See Installation, "Power Connections of the Transfer Switch".
- Make sure that all of the covers are installed and properly fastened. Also, make sure that all of the barriers are installed and properly fastened.
Note: During shipping, the transfer switch is in the NORMAL position.
A high potential test is performed at the factory. High potential voltage and megohmmeter tests are not recommended in the field. If you perform a high potential test or you perform a megohmmeter test in the field, disconnect the wiring harnesses from the controller. Also, disconnect the wiring harnesses from the R/T box. If you do not disconnect the controller, the high voltage can damage the controller. Also, if you do not disconnect the R/T box, the high voltage can damage the R/T box.
