1. An arrangement for monitoring an electrical safety interlock, the arrangement comprising:
a connector with a high-voltage electrical line, wherein the connector houses a jumper that is connected to a first section of a separate circuit and a second section of the separate circuit when the connector is connected to a high-voltage component, wherein the first and the second sections of the separate circuit are connected to a signal generation and evaluation unit that generates a continuous and value-discrete signal, wherein the signal generation and evaluation unit exhibits an output for outputting the signal, wherein the output is connected at least indirectly to the first section of the separate circuit, and wherein the second section of the separate circuit is connected at least indirectly to a first signal input and that the output is connected at least indirectly to a second signal input, wherein the signal provided by the signal generation and evaluation unit and output via the output is received by the signal generation and evaluation unit in a first channel via the second signal input without passing through the jumper, wherein the signal is received by the signal generation and evaluation unit via the first signal input in a second channel following transfer via the first section of the separate circuit, the jumper and the second section of the separate circuit, and wherein the monitoring of the electrical safety interlock is performed by the signal generation and evaluation unit through a comparison of the signal received via the first signal input in the second channel with the signal received via the second signal input in the first channel.
