In my 100 Watt ACI Drive circuit, I've confusion about which components will be best to connect between DC_Bus Ground & Earth?

FYI: 300 VDC for Motor & 15 VDC for Logics & other peripheral of MCU have common ground.

    \$\begingroup\$ What is an "ACI Drive" circuit? If it is a commercial device then please supply a link to the user manual and a page reference for the wiring scheme you are using. If you are adding an external controller then we need a schematic diagram. \$\endgroup\$ – Transistor Jun 25 at 7:12
  • \$\begingroup\$ it's Micro-controller based AC Induction Motor Drive circuit. \$\endgroup\$ – chinmay shah Jun 25 at 7:14
  • \$\begingroup\$ As it's a commercial product, what does the datasheet/instruction manual/user guide say? Often for a drive module, the DC lines to the motor should not be connected to anything other than the motor. But there may be a drive where that is not true. \$\endgroup\$ – Puffafish Jun 25 at 9:21
