Abstract
A work machine includes a power source, a plurality of connectors, and an isolator circuit. The power source is configured to provide power to an electrical system of the work machine. The plurality of connectors are for electrically connecting external components to the work machine and are configured to receive power from the power source. The isolator circuit is connected between at least one of the plurality of connectors and the electrical system of the work machine to selectively terminate power to the at least one of the plurality of connectors while the power source is providing power to the electrical system of the work machine.
Claims19
A work machine comprising:
- a power source configured to provide power to an electrical system of the work machine:
- a plurality of connectors for electrically connecting external components to the work machine, the plurality of connectors configured to receive power from the power source;
- and
- an isolator circuit connected between at least one of the plurality of connectors and the electrical system of the work machine to selectively terminate power to the at least one of the plurality of connectors while the power source is providing power to the electrical system of the work machine.
A method of electrical isolation for a work machine, the method comprising:
- powering, via a power source, an electrical system of the work machine;
- controlling an isolator circuit to terminate power to at least one of a plurality of connectors from the electrical system of the work machine;
- changing a connected state of at least one component with respect to the at least one of the plurality of connectors;
- and
- controlling the isolator circuit to reconnect power to the at least one of the plurality of connectors from the electrical system.
An electrical system of a work machine, the electrical system comprising:
- a machine electrical system connected to receive power from a power source of the work machine;
- a plurality of connectors for electrically connecting and disconnecting detachable components to the work machine, the plurality of connectors configured to receive power from the machine electrical system;
- and
- an isolator circuit connected between at least one of the plurality of connectors and the machine electrical system to selectively terminate power to the at least one of the plurality of connectors while the power source is providing power to the machine electrical system.
