Safety Precautions
WARNING: Failure to follow these safety instructions may result in electric shock, fire, or serious injury.
- Always ensure the transformer's wattage capacity (1500W) is greater than the total wattage of the appliances connected to it. Overloading can cause damage to the transformer and connected devices, and may pose a fire hazard.
- Do not expose the transformer to rain, moisture, or extreme temperatures. Use it in a dry, well-ventilated area.
- Ensure the input voltage selector switch is set correctly for the local power supply (e.g., 110V or 220V) before plugging in the transformer. Incorrect setting can damage the unit and connected appliances.
- Always connect the transformer to a grounded outlet.
- Do not open the transformer casing. There are no user-serviceable parts inside. Refer all servicing to qualified personnel.
- Keep out of reach of children.
- Unplug the transformer from the power source when not in use or before cleaning.
- Avoid placing the transformer near heat sources or in direct sunlight.
