■ 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 (Earth) must be connected to the Protective earth terminal of the
equipment.
If not connected, the conducted noise, radiation noise and output noise may increase.
(4) For Installation in Class II end equipment, terminal (Earth) is unnecessary to be connected to Protective earth
terminal of the equipment. The unit need to be fixed and it is insulated from any accessible conductive part by
reinforced insulation, so use a resin (insulating) spacer for fixing.
