Therefore, in order to preventelectric shock, or to meet the leakage current requirementsof the safety standard, you need to ensure the proper insulationdistance. Therefore, in order to prevent electric shock, or to meetthe leakage current requirements of the safety standard, you needto ensure the proper insulation distance.! In case of metal chassis, keep the distance shown as right fi gurebetween component and metal chassis for insulation, use thespacer of 8mm or more between bottom of power supply andmetalchassis. If it is less than reqired distance, insert the insulationsheet between power supply and metal chassis. The followingdistance is not satisfactory for cooling condition.Please refer to“Derating”.CN101d1Component sided1d1d15mm min8mm mind1=4mm minMounting screw!The mounting screw should be M3.
