damaged it must be replaced by the dedicated one.
6) The earthing should be reliable and the earth wire should be connected to the
dedicated device of the building by the professional personnel. Besides, the
air switch coupled with the leakage current protection switch must be
equipped, which is of enough capacity and of both magnetic and thermal
tripping functions in case of the short circuit and overload.

.
The specifications of the breaker and power cable listed in the table above are
determined based on the maximum power (maximum amps) of the unit.
②
.
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°С and
resistible to 90°С (see IEC 60364-5-52). If the working condition changes,
they should be modified according to the related national standard.
③
.
The specifications of the breaker listed in the table above are applied to the
breaker with the working temperature at 40°С. If the working condition
changes, they should be modified according to the related national standard.
(4) Earthing Requirements
1) The air conditioner is classified into the Class I appliances, so its earthing
must be reliable.
2) The yellow-green line of the air conditioner is the earth line and can not be
used for other purpose, cut off or fixed by the tapping screw, otherwise it
would cause the hazard of electric shock.
3) The reliable earth terminal should be provided and the earth wire can not be
connected to any of the following places.
a) Running water pipe.
b) Coal gas pipe.
c) Sewage pipe.
d) Other places where the professional personnel think unreliable.
