Note:
(1) Field wiring shall be in conformity to local laws and regulations, and all wiring operations must be
performed by qualified professionals.
(2) Refer to relevant standards for above-noted power cord size.
(3) Where power cord is connected through junction box, be sure to determine the total current and choose
wires based on the table above.
(4) As a minimum, the chosen power cord shall be compliant with requirements on neoprene sheathed
wire #57 as stated in IEC 60245-1, while the power cord shall be made from copper conductor.
(5) The wiring specifications for weak-current communication circuit shall not be lower than that for
RVV(S)P shielded wires or equivalent, and the shielding layer shall be grounded.
(6) A switch that can ensure all-pole disconnection shall be installed between power supply and air
conditioning unit in such a manner that the contact spacing shall not be less than 3mm.
(7) Once the power cord is damaged, the dealer or the professionals from designated maintenance
department must be contacted in a timely manner for repair and replacement.
(8) For the installation of power cord, the ground wire must be longer than the current-carrying conductor.
