## **MOUNTING INSTRUCTIONS** 

The VOF-150D series features four mounting holes, each with a diameter of 3.2 mm. There are three installation methods available. Please utilize the mounting holes as specified below: 

Insert the spacer (5.5 mm diameter max.) of 5 mm height or more to mount the unit 

Note:      M3 screw head and washer diameter must not exceed 5.5 mm.

## **MOUNTING INSTRUCTIONS (CONTINUED)** 

Please ensure a 4 mm side clearance from all components and edges of the PCB. Additionally, maintain a 5 mm clearance above the tallest components on the PCB. Pay special attention to providing a 5 mm gap between the solder side of the PCB and the mounting surface. Insufficient clearances will invalidate the isolation and withstand specifications. The VOF-150D series offers baseplate cooling to enhance heat dissipation. Refer to the following figure for installation details. 

Note:    The diameter of the M4 screw head and washer must not exceed 5.5 mm. Ensure a 4 mm side clearance from all components and edges of the PCB. Maintain a 5 mm clearance above the tallest components on the PCB. Pay special attention to providing a 5 mm gap between the solder side of the PCB and the mounting surface. Failure to maintain these clearances will invalidate the isolation and withstand specifications. 

## Base Cooling Setup 

Ensure that the PE (Protective Earth) is connected to the ground terminal of the apparatus. Failure to do so will result in increased conducted and output noise.
