• Get the power cable and the connection cables.
• All the cables shall have got the European authentication certificate. During installation, when the connecting cables break off, it must be
assured that the grouding wire is the last one to be broken off.
• The explosion-proof breaker of the air conditioner should be all-pole switch. The distance between its two contacts should not be no less
than 3mm. Such means for disconnection must be incorporated in the fixed wiring.
• The distance between its two terminal blocks of indoor unit and outdoor unit should not be over 5m. If exceeded, the diameter of the wire
should be enlarged according to the local wiring standard.
• A explosion-proof breaker must be installed.
Wiring procedure
• Remove set screws on the side before taking off the front panel toward the direction.
• Connect Wires to the terminal block correctly and fix the wires with a wire clamp equipped nearby the terminal block.
• Route the wires in a proper way and penetrate the wires through the opening for electrical wiring on the side panel.
WARNING
Interconnecting wires must be wired according to figure below. Incorrect wiring may cause equipment
damage.
