multi-wire copper cable (like, YJV copper cable, consisting of PE insulated wires and a PVC cable
jacket) used at 40
℃
(104
℉
) and resistible to 90
℃
(194
℉
), and shall be at least those of ordinary
polychloroprene sheathed cords. If the working condition changes, they should be modified according
to the related national standard.
4)
The specifications of the air switch listed in the table above are applied to the breaker with the working
temperature at 40
℃
(104
℉
). If the working condition changes, they should be modified according to the
related national standard.
5)
The length of the recommended power cable should be less than 15meters(49feet); otherwise, the
diameter of the power cable is not enough.
6)
Mentioned power cable and transmission line length is just a reference value. It may be different
depending on the condition of installation, humidity or materials, etc.
7)
An all-pole disconnection switch having a contact separation of at least 3mm(1/8 inch) in all poles
should be connected in fixed wiring.
6.3
Ground Requirements
WARNING
1)
The air conditioner is classified into the Class I appliances, so its ground ways must be reliable.
2)
The ground wire must be fixed on the screw hole with the sign as the right figure.
3)
The yellow-green wire of the air conditioner is the ground wire and must be fixed by the tapping screw.
And it cannot be used for other purpose or cut off. Otherwise, it will cause the hazard of electric shock.
4)
The reliable ground terminal should be provided and the ground wire cannot be connected to any of the
following places: a. Water pipe; b. Coal gas pipe; c. Sewage pipe; d. Lightning rod
e. Telephone line f. Other unreliable places considered by a professional.

Precautions on the Electrical Wiring Work
WARNING
1)
The electrical installation should be carried out by the professional as instructed by the local laws,
regulations and also this manual.
2)
The ground connection should be reliable and the ground wire should be connected to the dedicated
device of the building by the professional.
3)
Before starting work, the power must not be supplied to the unit.
4)
The air switch coupled with the leakage current protection switch must be equipped in the circuits,
which is of enough capacity and of both magnetic and thermal tripping functions in case of the short
circuit and overload.
5)
The electrical work should use a cable length enough to cover the entire distance with no connection. If
it is unavoidable, please make sure the connection should be reliable, the external forces will not act on
the wires and the joint is not bared. Otherwise it will cause electrical shock or fire etc.
6)
The power cable with the rated voltage and exclusive circuit for the air conditioner should be used.
7)
Do not pull the power cable by force after it is installed.
8)
The diameter of the power cable should be large enough and once it is damaged, it must be replaced by
the dedicated one.
9)
The multi-wire copper cable should be used for the power cable and the transmission line.
