Before activating the power to the transformer, what must be replaced?

Before activating the power to the transformer, replacing all doors, devices, and covers is crucial to ensure safety and proper functionality. Transformers are designed with various protective elements, including doors, covers, and devices that safeguard both the internal components and external users from electrical hazards.

By ensuring that all doors are securely closed, devices are properly installed, and covers are in place, you minimize the risk of accidental contact with live components. This also helps prevent dust and foreign objects from entering the transformer, which can cause malfunctions or electrical failures. It is essential for safe operation and compliance with safety standards that all protective measures are in place before energizing the equipment. Neglecting any one of these components could pose dangers, such as electrical shock or equipment damage.
