5-3. Mounting Method
5-3-1. Mounting method for standard model
Note: Except /A, /B and /G2 model.
All four mounting holes on this model should be utilized for best electrical and mechanical performance, with 8mm
(minimum height) metal standoffs.
Mounting Holes size
4 holes
φ
3.5mm.
Refer to the shadow in the figure below for allowable area touched by conductive material on top and bottom side of the PCB.
Condition to meet EMI, EMC, Isolation, Withstand Voltage and Cooling requirement.
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.
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.
terminal (Protective Earth) must be connected to the earth terminal of the equipment, also the two mounting holes (as
shown below) needed to be connected to earthed metal plane or metal chassis of end product by metal spacer to ensure EMC
and EMI 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.
