What should be done before servicing a product that contains high voltage?

Before servicing a product that contains high voltage, discharging the high voltage is crucial for safety. High voltage components can retain electric charge even when the power is turned off, posing a significant risk of electric shock. By discharging these components, you ensure that any stored electrical energy is safely released, reducing the likelihood of injury while working on or near the equipment.

This step is essential for maintaining a safe working environment, as it addresses the potential danger presented by residual charges in capacitive components or power supplies. Always using the proper technique and tools when discharging high voltage is critical to ensure safety.

While disconnecting the battery, switching off the main circuit breaker, and placing safety barriers can all be part of a comprehensive safety protocol, they alone do not ensure that dangerous voltages are eliminated from the components being worked on. Discharging the high voltage is a direct action that mitigates immediate risks associated with residual energy in electrical components.
