Safety and Precaution Guide for Enclosure Installation
Enclosure Design Guide
•Design the heat dissipation system so that the panel surface temperature does not exceed 75 °C (167 °F) under
direct sunlight in the installation area. Quality assurance is not provided for failures such as yellowing and black circles
that occur when the panel temperature exceeds 75 °C (167 °F) due to lack of Air Gap 10 mm (0.39 inches), not
applying UV protection function, and insufficient heat dissipation performance.
•Observe the following to ensure that the panel surface temperature does not exceed 75 °C (167 °F).
Air Gap
•Keep at least 10 mm (0.39 inches)
between the panel and the enclosure
protective glass to allow air to flow.
