- Altering anything to do with the circuitry.
• Check that the device is not live.
• Check the work area for any potential hazards such as damp or wet oors, defective extension cords or protective
conductors.
Additional precautions when dealing with open voltage supply:
• Request a second person to stay in the vicinity and operate the emergency powers or mains switch if and when
required.
