When disconnecting the power supply, thecurrent-carrying connections must be separated before theearth connection is. The length of the conductors betweenthe power supply stress relief and the terminal block itselfmust be as such that the current-carrying wires aretautened before the earth wire is in case the power supplyis pulled loose from the stress relief.NOTICEPrecautions when laying power wiring:▪ Do NOT connect wiring of different thicknesses to thepower terminal block (slack in the power wiring maycause abnormal heat).▪ When connecting wiring which is the same thickness,do as shown in the figure above.▪ For wiring, use the designated power wire and connectfirmly, then secure to prevent outside pressure beingexerted on the terminal board.▪ Use an appropriate screwdriver for tightening theterminal screws. A screwdriver with a small head willdamage the head and make proper tighteningimpossible.▪ Over-tightening the terminal screws may break them.WARNING▪ After finishing the electrical work, confirm that eachelectrical component and terminal inside the electricalcomponents box is connected securely.▪ Make sure all covers are closed before starting up theunit.NOTICEOnly applicable if the power supply is three‑phase, and thecompressor has an ON/OFF starting method.If there exists the possibility of reversed phase after amomentary black out and the power goes on and off whilethe product is operating, attach a reversed phaseprotection circuit locally.
