PURPOSE:To miniaturize a naturally cooling outdoor control panel set up in the outdoor where temperature variation is high and corrosion gas, dust or the like exists. CONSTITUTION:Electrical parts can be set by surface-mounting to a casing by surrounding the casing of an outdoor control panel with a plastic shade plate, with foamed plastic pasted to the inside of hard plastic, and also by providing a naturally ventilating slit and a recessed part for receiving the end of a mounting screw on the inside of the plastic shade plate. |
