12. Wiring design Warning :In European Market :local 3 phase isolator (power switch) must be fitted locally to the unit (Legal requirement for EU). For other area, pls. comply with local regulation requirement. Electric wiring should be executed by the specialized well-trained person. Warnings: A. Do not take the other wire except for copper wire as the power cable. B. All indoor/outdoor units must be connected with the earthing wire of power cable. The earthing wire can not be connected onto the earthing wire of coal gas pipe, water pipe, lightning rod, or telephone. Or the electric shock or fire will occur. C. Must install the leakage breaker and the over current breaker, or electric shock will occur. D. Before finishing electric installation, do not electrify the unit. E. Indoor and outdoor use their individual power source. All indoors use one power source. F. The communication wire and the power cable must be individual and can not use one multi-core cable, or the communication wire will be interfered to cause abnormal. Note: When one wired controller controls multiple indoors, the connected indoor units must use the common phase of power source, or the communication will be abnormal.For example, the power source is L1,L2,L3,and N, all the indoor units must use L1/N or L2/N or L3/N. 1.
