.5.1 Electrical Wiring
Notes:
(1) A dedicated power supply must be used for the air conditioner. The voltage of the power supply must
comply with the rated voltage.
(2) The wiring construction must be carried out by professional technicians based on the circuit diagram
label.
(3) The power and ground cables must be tightened by using an appropriate tool with a proper torque.
(4) The power and ground cables must be crimped securely and checked from time to time to prevent
looseness.
(5) Only electrical components specified by our company can be used, for which you must request the
manufacturer or authorized dealer to provide related installation and technical services. If the wiring
does not meet the electrical installation standard, the controller may work improperly or an electric
shock may occur.
(6) An incoming circuit breaker must be installed on the fixed line.
(7) Electric leakage protection devices must be set correctly based on the requirements in relevant
technical standards of electrical equipment.
(8) The power supply can be connected only when no error is found after all wiring operations are
complete.
(9) Read each label attached on the electric control box carefully.
(10) Do not try to repair the machine by yourself. If the controller is repaired improperly, an electric shock
may occur or the controller may work improperly. If you have any repair demand, contact the repair
center of after-sale.
