Always use either thermal grease or a thermal sheet.If processing thermal grease, apply it thinly and evenly.Also, when processing the thermal sheet, make a hole according to the position of the screw.If the four corners are cut as shown in the fi gure below, stress may be applied to the edges of the base plate during fi xing, which maydamage the built-in parts, so avoid such processing.Good Bad BadImage of using thermal sheet and precautions when processing!The unit can be mounted in any direction. When two or more power supplies are used side by side, position them with proper intervalsto allow enough air ventilation. Aluminum base plate temperature around each power supply should not exceed the temperature rangeshown in“Derating”.!Avoid placing the AC input line pattern lay out underneath the unit, it will increase the line conducted noise. Make sure to leave an ampledistance between the line pattern lay out and the unit. Also avoid placing the DC output line pattern of DC-DC converter underneath theunit because it may increase the output noise. Lay out the pattern away from the unit.!High-frequency noise radiates directly from the unit to the atmo- sphere. Therefore, design the shield pattern on the printed circuit boardand connect its one to FG. The shield pattern prevents noise radiation.DPG-4
