Note:       1. For Class I applications, all four mounting hole positions must be securely connected to the protective earth ground during the final system assembly to ensure optimal safety and EMI performance. 

2. For Class II applications, the four mounting hole positions must remain isolated from one another. Each mounting hole should be fixed to the chassis using insulated spacers. 

3. To enhance EMI performance under Class II test conditions, the VOF-65G Series allows an additional clamp core to be applied with one turn on the AC input.
