In order to prevent electric shock, or to meet the leakage current requirements of the safetystandard, you need to ensure the proper insolation distance.!During use, keep the distance between d1 & d2 for to insulate between lead of component and metal chassis, use the spacer of 5mm ormore between d2. If it is less than d1 & d2, insert the insulation sheet between power supply and metal chassis.!Conduction cooling, forced air and convection cooling are available (GHA500/700F).When using conduction cooling, unless the baseplate and the heat sink are placed in close contact with each other, contact thermal resistancewill increase until heat dissipation becomes insuffi cient.Always use eithe thermal greaser 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 may damagethe built-in parts, so avoid such processing.Good Bad BadImage of using thermal sheet and precautions when processing?
