1. The intelligent temperature control box power supply is three-phase four-wire AC 380V/50Hz, (single point and two point temperature) The control box adopts single-phase two-wire 220V/50Hz), which is marked with NEUTRAL as zero line, marked with EARTH as the ground line, and the other three are phase lines. (Note: the zero line must be connected correctly, otherwise the instrument will be damaged) Power input The program must first input the total power supply, and then turn on the temperature control box switch. When the use is stopped, the intelligent temperature control box switch is turned off first, and then the total power supply is turned off.
