Condition to meet EMC, Isolation, Withstand Voltage and Cooling requirement.
(1) Keep 4mm space minimum from the surface and sides of power supply, 8mm space minimum from the bottom side
of PCB to meet safety requirement, or more space depend on safety requirement. If the space is not enough, the
specification of isolation and withstand voltage will not be satisfied.
(2) More space may be required in the surrounding of power supply and the upper area of components for effective
cooling depends on the application conditions.
(3) For installation in Class I end equipment, terminal (Protective Earth) must be connected to the earth terminal of the
equipment, also the mounting hole B (as shown below) needed to be connected to earthed metal plane or metal
chassis of end product by metal spacer to ensure EMC performance. All equipment ideally should be mounted inside
an earthed shielded metal box. Alternatively an earthed metal plate can be used to mount the power supply and load.
Please use insulator material studs for application in altitude more than 4000m up to 5000m.
(4) For Installation in Class II end equipment terminal (Protective Earth) is unnecessary to be connected to earth
terminal of the equipment.
