Haier AW052MUCHA - Electric Wiring and Application

22
General check
• Make sure that the following conditions related to power supply installation are satised:The power capacity of the
electrical installation is large enough to support the power demand of the HAIER system.
The power supply voltage is within ±10% of the rated voltage.
The impedance of the power supply line is low enough to avoid any voltage drop of more than 15% of the rated
voltage.
• Following the Council Directive 2004/108/EC, relating to electromagnetic compatibility, the table below indicates the
Maximum permitted system impedance Zmax at the interface point of the user’s supply, in accordance with EN61000 3

WARNING
• Switch off the main power switch of the indoor and outdoor machine for more than 1 minutes before the wiring or
regular inspection.
• To prevent the destruction of wires and electrical components by rats or other animals. Serious, it may lead to the
occurrence of re.
• To avoid damage to the wire, avoid contact with refrigerant pipes, steel edges and electrical components. Serious, it
may lead to the occurrence of re.
CAUTION
• Secure the power cord with a wire tie in the machine.
Note:
when the wiring of the outdoor machine is not using the wire, it should be xed with the rubber ring.
Inspect
• To ensure that the electrical equipment used on the installation site (main power switch, circuit breaker, wire, conduit
and wiring terminals, etc.) have been selected according to current data, to ensure that the device in line with national
standards.
• Check the power supply voltage in the range of 10% of the rated voltage and the ground wire is included in the power
supply line. Otherwise, electrical parts will be damaged.
• Check whether the power supply is satised. Otherwise, the compressor will not start when the voltage is too low.
• By measuring the insulation resistance between the ground and the electrical device terminals, to ensure that more than
1 MΩ. Otherwise, the system can not be started until the cause of leakage and maintenance.
Connection
• Connect the power cord to the terminal of the indoor unit and the outdoor mechanical and electrical gas box, connect
the ground wire to the grounding bolt of the outdoor machine and the indoor mechanical and electrical air box.
• Connect the external and internal communication lines to the 1 and the 2 terminals on the terminal. If the power cord is
connected, the printed circuit board will be damaged. And the use of shielded twisted pair wire.
• Do not connect the fastening screws on the front of the cover.
• The power cord must be made of copper wire, and the power supply must be in line with IEC 60245 requirements. If the
power cord length exceeds 20m, the need to increase the size.
• The power supply line is xed with a round connection terminal with an insulating protective sleeve. Not with sheet
metal contact and extrusion, in order to avoid the cut line of skin caused by re.
The cord of the H07RN-F type or the electrically equivalent type must be used for power connection and interconnection
between outdoor unit and indoor unit.
