What is the first step before removing or installing a replacement power converter?

Call a technician
Restore power to the circuit
Disconnect battery and AC power supply
Inspect the power converter

The correct answer is: Disconnect battery and AC power supply

Before removing or installing a replacement power converter, it is essential to disconnect the battery and AC power supply. This step is crucial for safety reasons. Working with electrical components poses risks, such as electric shock or short circuiting, especially if the unit is still powered. By disconnecting the battery and unplugging the AC power supply, the technician ensures that there is no current flowing through the system, eliminating these risks. Restoring power to the circuit, calling a technician, or inspecting the power converter should not be the initial steps, as they do not address safety concerns. Without disconnecting power, proceeding with any further actions could be dangerous. Therefore, ensuring that there is no active power in the system is a fundamental safety protocol before undertaking any electrical work on the power converter.
