1. Before connecting the power supply, please confirm the wire diameter of the external power supply: whether the capacity of the main switch meets the requirements of the equipment.
2. Please use a multimeter to confirm whether the power supply voltage is normal (allowing ±10% RH deviation), the voltage between the phase lines is 380V, and whether the phase line and the neutral line are 220V. After no problem, turn off the main switch;
3. Connect the zero line (blue N line) of the machine to the neutral terminal in the distribution box. (The zero line must be connected, otherwise the equipment will not work, or burn electrical components);
4. Connect the three phases of the RST of the machine to the three terminals at the lower end of the main switch of the distribution box, and ensure that the screws are tightened.
5. Connect the grounding wire of the machine to the grounding terminal of the distribution box; explain the wiring steps of the high and low temperature test box circuit specification;
Note: The high-low temperature test chamber is designed with phase sequence protection. If the phase sequence is wrong, the instrument will not be energized when the machine is turned on. You need to change the position of the two lines at the lower end of the main switch of the distribution box. The phase sequence can be changed to meet the requirements of the test chamber.
