Hi Folks, I have a safety question for the group. I have a small (about 8 x 10 x 2 inch) piece of ITE equipment, SELV, enclosed in a plastic case, powered by an external 12 volt brick from AC mains.
The problem is, the device tends to run a little hotter than desired. One proposed solution is to cut some vent holes in the top. These would be roughly (1/2) inch long by (1/6) inch wide, spaced (1/4) inch apart, running across the top near the front of the device. I haven't seen many (any?) devices with vent holes in the top, so I'm wondering if there is a basic reason why not, such as the cover must shed water, etc. My questions are, what considerations arise and what sections of EN 60950 apply to this, either to allow it or to exclude it.
