The specifications of the power cable listed in the table above are applied to the
conduit-guarded multi-wire copper cable (like, YJV copper cable, consisting of PE insulated
wires and a PVC cable jacket) used at 40
and resistible to 90
ć
ć
, 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.
The specifications of the air switch listed in the table above are applied to the breaker with the
working temperature at 40
. If the working condition changes, they should be modified
ć
according to the related national standard.
The length of the recommended power cable should be less than 15 meters; otherwise,
the
diameter of the power cable is not enough.
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.
An all-pole disconnection switch having a contact separation of at least 3mm in all poles should
be connected in fixed wiring.

7.3 Ground Requirements
The air conditioner is classified into the Class I appliances, so its ground ways must be reliable.
The ground wire must be fixed on the screw hole with the sign as the right figure.
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.
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.
7.4 Precautions on the Electrical Wiring Work
The ground connection should be reliable and the ground wire should be connected to the
dedicated device of the building by the professional.
The electric installation should be carried out by the professional as instructed by the local laws,
regulations and also this manual.
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.
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.
The power cable with the rated voltage and exclusive circuit for the air conditioning should be
used.
Do not pull the power cable by force after it is installed.
The diameter of the power cable should be large enough and once it is damaged, it must be
replaced by the dedicated one.
The multi-wire copper cable should be used for the power cable and the transmission line.
