For the location of theterminals, see the wiring diagram.▪ Do NOT touch electrical components with wet hands.▪ Do NOT leave the unit unattended when the servicecover is removed.WARNINGIf NOT factory installed, a main switch or other means fordisconnection, having a contact separation in all polesproviding full disconnection under overvoltage category IIIcondition, shall be installed in the fixed wiring.WARNING▪ ONLY use copper wires.▪ Make sure the field wiring complies with the applicablelegislation.▪ All field wiring must be performed in accordance withthe wiring diagram supplied with the product.▪ NEVER squeeze bundled cables and make sure theydo not come in contact with the piping and sharpedges. Make sure no external pressure is applied to theterminal connections.▪ Make sure to install earth wiring. Do NOT earth the unitto a utility pipe, surge absorber, or telephone earth.Incomplete earth may cause electrical shock.▪ Make sure to use a dedicated power circuit. NEVERuse a power supply shared by another appliance.▪ Make sure to install the required fuses or circuitbreakers.▪ Make sure to install an earth leakage protector. Failureto do so may cause electric shock or fire.▪ When installing the earth leakage protector, make sureit is compatible with the inverter (resistant to highfrequency electric noise) to avoid unnecessary openingof the earth leakage protector.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 below.▪ 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.Install power cables at least 1 metre away from televisions or radiosto prevent interference. Depending on the radio waves, a distance of1 metre may not be sufficient.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. Running the product in reversedphase can break the compressor and other parts.2 About the documentation2.1 About this documentTarget audienceAuthorised installersINFORMATIONThis appliance is intended to be used by expert or trainedusers in shops, in light industry and on farms, or forcommercial use by lay persons.Documentation setThis document is part of a documentation set.
