4. Setup and Installation

4.1 Mounting

Mount the VFD in a vertical position on a flat, non-flammable surface. Ensure adequate clearance around the unit for proper ventilation and heat dissipation. Avoid mounting in direct sunlight or areas with high vibration.

4.2 Wiring Diagram (4KW-15KW)

Follow the wiring diagram carefully for correct and safe installation. Ensure all connections are secure and properly insulated.

Wiring Connections:

• Input Power (R, S, T): Connect your single-phase or three-phase 220V AC power supply to terminals R, S, and T. For single-phase input, connect the live and neutral wires to R and S (or R and T), leaving the third input terminal unused.
• Output to Motor (U, V, W): Connect the three-phase motor's input terminals to U, V, and W on the VFD.
• Grounding (⚧): Connect the VFD's grounding terminal to a reliable earth ground. Ensure the motor is also properly grounded.
• Braking Resistor (P+, PB): If an external braking resistor is used, connect it between terminals P+ and PB. This is optional and used for applications requiring rapid deceleration.

Note: Always consult local electrical codes and standards for proper wiring practices.
