If both the power supply and the nearby equipment are the heat sources (e.g., dimmers, LED light panels, LED matrices), please pay attention to the following points: 
1. In order to avoid the risk of overheating, the direction of the power supply should be parallel for the convection and keep a distance for more than 3 cm between the power supply and the equipment.
2. Do not install the power supply upside down.
3. Make sure the ambient temperature is in the range of normal operating temperature. 

If the power supply is mounted in an unventilated and confined space such as waterproof box, inner space of an equipment or system, etc., please make sure the temperature of the power supply enclosure is lower than tc (Case Temperature).
