Household 220 Volt Wiring for VFD

Electrical installation and voltage changes must be performed by a qualified electrician using the instructions for the exact VFD and motor.

Confirm the incoming supply

The input supply to a VFD and its output to a motor are different circuits. A three-phase motor does not by itself establish what incoming supply your drive requires.

Use the VFD model/rating label, ordered input-voltage configuration and manufacturer’s wiring documentation. Do not choose a connection by wire color, plug appearance or a generic diagram alone.

If the package does not include an input plug

Have the electrician select the correct connection and verify voltage, grounding, circuit protection and the drive configuration before operation. Do not connect an unknown or modified configuration to power.
