Proper wiring is critical for the safe and correct operation of the frequency converter. Refer to the diagrams below and ensure all connections are secure.
5.1. General Wiring Diagram
Image Description: This detailed wiring diagram illustrates the comprehensive connection points for the Jadeshay VFD. It shows connections for three-phase power input (R, S, T), multi-function terminal inputs (X1/FWD to X7, COM), analog inputs (AI1, AI2, GND, +10V), programmable relay outputs (TA1/TA2, TB1/TB2), open collector output (Y1/Y2, DO, +24V), analog outputs (AO1, AO2, GND), and RS485 communication (+485, -485). It also depicts connections for braking resistors for different power levels (22KW and below, 30KW and above) and the three-phase induction motor (U, V, W).
5.2. 220V Inverter Basic Wiring
Image Description: This image provides a simplified wiring diagram for connecting the 220V inverter. It clearly shows the connections for a single-phase 220V power supply to terminals R and S, the ground wire to the ground terminal, and the three-phase motor to terminals U, V, and W. It also notes that the machine has a built-in braking resistor, and an external one can be connected at the P+/PB position if required.
Terminal Connections:
- R, S: Single-phase 220V AC power input.
- Ground Symbol: Connect to earth ground for safety.
- U, V, W: Three-phase output to the motor.
- P+, PB: Connections for an optional external braking resistor. The unit has a built-in braking resistor.
Important: Ensure correct phase sequence for motor rotation. If the motor rotates in the wrong direction, swap any two of the U, V, W output wires.
