1. Before use, be sure to read the product manual carefully and follow the correct operating procedures. If you have any questions, consult a professional immediately. Never perform any inspections or repairs on your own, as this can easily lead to safety hazards.
2. During operation, never overload the transformer. If the transformer is overloaded for a long time, the internal coils will heat up and the insulation will degrade, leading to short circuits between phases or switches.
3. To ensure the normal operation of the transformer and effectively extend its lifespan, it is recommended to apply high-quality insulating oil to the transformer. Poor-quality insulating oil containing impurities can reduce the transformer's insulation strength and cause fires and other accidents.
