In general, the three-dimensional packaging machine voltage of 380 volts or 220 volts two, its electrical power of 7.5 kilowatts, so its current is still relatively large, therefore, it should be noted that it can not be plugged directly into the socket above, or there will be a greater safety hazard. Therefore, the correct way to connect the wire of the three-dimensional packaging machine is to install a 220-volt or 380-volt air switch on top of the wall, and then the machine's wire to this air switch above, only then can be used. (Note: the air switch needs more than forty kilowatts, the size of the wire needs to be more than six square.)
For 220-volt three-dimensional packaging machine, if the 220-volt machine is connected to the 220-volt air switch above, this is very simple, because there are only two lines, directly connected to it. But if you want to connect the 220-volt machine to the 380-volt air switch above, how to do it? Connect one of the machine's power cord to any of the fire wire above the air switch. Then the machine's other power cord please receive the zero wire of the air switch above, so that you can.
Then the three-dimensional packaging machine of 380 volts and how to wire it?
We must first find the three fire lines of the power supply, the three fire lines to the three fire lines of the air switch above the interface.
Then open the machine's power supply, press the down button with your hand, put your finger in the vacuum chamber on the table of the pumping holes (a total of six small pumping holes) there to feel, if your finger feels the air sucked below, it means that the vacuum pump is positive; if your finger does not feel the suction, and the sound of the vacuum pump is relatively large, which means that the vacuum pump reverses.
Then we need the machine power line of the three wiring of two of the wiring to adjust the air switch and then connected to the top, the vacuum pump can be positive.
