Installation Information:

Generator control boards involve utility voltage, generator output voltage, battery power, and sensitive electronic components. Installation and diagnosis should be completed by a qualified generator technician.

Before servicing, follow the manufacturer’s complete shutdown procedure and isolate every power source, including utility power, generator power, and the starting battery. The technician should confirm wiring, generator configuration, output voltage, frequency, and all required controller settings before returning the unit to service.

This board should not be advertised as universally compatible, preprogrammed, or plug-and-play unless those details have been confirmed for the specific generator. Verify the complete model and serial numbers and the number printed on the original control board before ordering.
