Coaxial power connectors make two or more connections by plugging a single, round connector into a single hole. Usually the outer surface of the plug makes the ground connection and the inner portion makes the voltage connection. Some coaxial power plugs have connections along a shaft, insulated between sections. Connections to the plug can be screw lugs, wire wrap or solder terminals. An outer cover insulates the connections. To wire a coaxial power connection, you need basic wiring skills to either crimp, wire wrap or solder.
Remove the outer covering from the back of the coaxial power connector to expose the connections. Some screw on and off, others simply pull off and others have a small set screw holding them in place.
Slide the cover over the wire you use to make the connection. Failure to do this may force you to disassemble the connection to put it on.
Make the appropriate connection for the type of hardware on the connector. This may require you to crimp a terminal lug onto the wire and put it under a set screw, use a wire-wrap tool to turn the wire around a pin or make a solder connection.
Slide the power connectors cover back onto the connector body and reinstall it in an opposite order from the way you removed it.
