A monitoring apparatus of an onboard electrical system of an at least partially electrically operated motor vehicle. A switchgear is configured to switch a high-voltage positive path and a high-voltage negative path of an electrical energy storage device of the onboard electrical system. The switchgear has a control line which is coupled to a pyrotechnic safety device. In an event of an interruption of the control line, the switchgear opens the high-voltage positive path and the high-voltage negative path. A control line switchgear is series-coupled in the control line to the pyrotechnic safety device. The control line switchgear interrupts the control line as a function of a control signal of an electronic computing device. The electronic computing device is configured to check a voltage potential in the control line using the control line switchgear before the electrical energy storage device is connected to the onboard electrical system.
