The voltage of a general machine spring machine is almost 60 volts. Above 60 volts is abnormal. This needs to be handled properly.
At this time, the power needs to be disconnected. Generally speaking, an ordinary wire can be connected to the domestic hot metal pipe. If the power supply has a ground wire, it can be connected to the machine's power ground wire, and then an iron rod is inserted to the depth of one meter Left and right, then connect the machine with a wire.
If the measured voltage is between 200 volts and 220 volts, the skin of the machine's wiring is damaged. First see if the wiring of each fan is damaged, then check if the wire from the corner of the machine to the controller is damaged. If not, check with exclusion method.
If the voltage measurement is above 60 volts, and below 150 volts and a power trip occurs, then there may be a string of power, especially in the case of a crash. It is suggested that it can be solved by connecting it to ordinary life electricity.
