Ground Requirements; Precautions On The Electrical Wiring Work - Vivax ACP-56COFM164GEEI User Manual

conduit-guarded multi-wire copper cable (like, YJV copper cable, consisting of PE insulated
wires and a PVC cable jacket) used at 40
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
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.

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
♦
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 power supply of the outdoor unit and all the BU modules should be separately.
♦
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 and the
external forces will not act on the wires. 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.
♦
The diameter of the power cable should be large enough and once it is damaged, it must be
replaced by the dedicated one.
