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 intervals toallow enough air ventilation. Aluminum base plate temperature of each power supply should not exceed the temperature range shown in“derating”.!Avoid placing the DC input line pattern layout underneath the unit. It will increase the line conducted noise. Make sure to leave an ampledistance between the line pattern layout and the unit. Also avoid placing the DC output line pattern underneath the unit because it mayincrease the output noise. Lay out the pattern away from the unit.!Avoid placing the signal line pattern layout underneath the unit because the power supply might become unstable. Lay out the patternaway from the unit.!High-frequency noise radiates directly from the unit to the atmosphere. Therefore, design the shield pattern on the printed circuit boardand connect it to FG. The shield pattern prevents noise radiation.!When a heat sink cannot be fi xed on the base plate side, order the power moduleMounting holewith“-T”option. A heat sink can be mounted by affi xing a M3 tap on the heat sink. Standard M3 tappedPlease make sure a mounting hole will be connected to a grounding capacitor CY. Optional : -T f3.4 thruDCS-4
