Even when unplugged, the main input filter capacitor retains hundreds of volts DC across its leads. Use a high-wattage power resistor to discharge it securely before touching the under-board solder pads.

To keep your battery and its internal circuitry in top shape: Even when unplugged, the main input filter capacitor
Before diving into the schematic pathways, it helps to understand what the governs under the hood: Even when unplugged
Completes the main current return path.
If you want any of the detailed deliverables above (e.g., CAD-ready wiring diagram or VFD parameter sheet), tell me which one and provide the exact motor voltage and rated power so I can produce it.
