What if it say the machine should be properly grounded?

If a machine should be properly grounded, it means that it must be connected to the earth or a ground point to prevent electrical shock and protect against electrical surges. Proper grounding ensures that any stray electricity is safely redirected, minimizing the risk of injury to users and damage to the equipment. It is essential for maintaining safety standards and compliance with electrical codes. Always follow manufacturer guidelines and local regulations when setting up grounding.
