Electrical Wiring

• Electrical connections should be made with specific main circuits by the qualified personnel according to the installation
instruction. Electric shock and fire may be caused if the capacity of power supply is notsufficient.
• While arranging the wiring layout, specified cables should be used as the main line, which conforms to the local
regulations on wiring. Connecting and fastening should be performed reliably to avoid the external force of the cables
from transmitting to the terminals. Improper connection or fastening may lead to burning or fireaccidents.
• Ground connection should match specifications. Unreliable grounding may cause electrical shocks. Do not connect the
grounding line to the gas pipe, water pipe, lightening rod, or telephoneline.
• Only copper wires can be used. Breaker for electric leakage must be provided or electric shock mayoccur.
• The wiring of the main line is of Y type. The L terminal should be connected to the live wire and N terminal should be
connected to the null wire and the ground terminal should while should be connected to the ground wire. For the type
with auxiliary electrical heating function, the live wire and the null wire should notbe misconnected, or the surface of the
electrical heating body will be electrified.
• If the power line is damaged, professional personnel from the manufactureror the service centre should replace it.
• The power line of indoor units should be arranged according to the installation instruction for indoor units.
• The electrical wiring should be away from high-temperature sections of tubing so as to avoid the melting of the insulating
layer of the cables, which may causeaccidents.
• After connecting to the terminal tier, the tubing should be curved into be a U-type elbow
and fastened with the pressing clip.
• Controller wiring and refrigerant tubing can be arranged and fixedtogether.
• Maintenance should be done while the power is shut down.
• Seal the thread hole with heat insulating materials to avoid condensation.
• The signal and power lines are independent and cannot share one line. [Note: the power and signal lines are provided
by users. Parameters for power lines are shown as below:3×(1.0-1.5)mm2;
• parameters for signal line: 2×(0.75-1.25)mm2 ( shielded line)]
• The machine is equipped with 5 butt lines (1.5mm) before delivery, which are used for connections between the valve
box and the electrical system of the machine. A detailed diagram of the connection is displayed in the circuitdiagram.
• The machine must be connected to the ground according to EN 60364.
• Periodically check and ensure to tighten the pressurelugs.

• Indoor and outdoor units should be connected to the power source separately. Indoor units can share one single
electrical source, but their capacity and specifications should be calculated. Indoor and outdoor units should be
equipped with power leakage and overflow breakers.
