5-3-2. Mounting method for /B model
/B model is optional model with metal plate on the bottom.
The mounting holes on the metal plate are for power supply fixing. The M3 stud near the input connector is used to connect to
the protective earth.
Refer to the /B model outline drawings for the detailed dimensions.
Mounting Holes
A:
3-
φ
3.5 holes for mounting screws to fix the power supply from top.
B:
3-M3 tapped, embossed and countersink holes for mounting screws to fix the power supply from bottom.
Ground: M3 stud for protective earth
Condition to meet EMI, EMC, Isolation, Withstand Voltage and Cooling.
Keep more than 4mm space from the top of components and the sides of PCB to meet 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.
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 to ensure the EMI and EMC performance.
5-3-3. Mounting method for /A model
/A model is optional model with metal chassis and cover.
The mounting holes on the bottom of the chassis are for power supply fixing. The M3 stud near the input connector can be
used to connect to the protective earth.
Refer to the /A model outline drawings for the detailed dimensions.
