Refer to Tables 5-2&5-3 for the specifications of the power cord and communication wire. A wiring capacity that is too small will cause the
electrical wiring to become too hot, and lead to accidents when the unit burns and becomes damaged.

Please refer to the corresponding wired controller manual for the wired
controller wiring.
Select the wire diameters( minimum value) individually for each unit based on the table 5-3.
Maximum allowable voltage range variation between phases is 2%.
