What did the mobile phone counter miss?

There may be something wrong with the wire or sensor, so it is recommended to find professional maintenance personnel to repair it.

Details may be as follows:

1. Induced leakage. Because the control circuit of the compressor unit and the lighting circuit in the box pass through between the shell and the inner wall of the box, there is a certain distributed capacitance, and the compressor unit generates self-induced potential when rotating with the induction motor. At this time, if there is no safe and reliable grounding wire in the display cabinet, people may feel numb when touching the cabinet. Therefore, when installing the counter, the grounding wire should be connected to make the box reliably grounded.

2. Poor contact. Loose contact control, copper wire connected to the shell, or wrong wiring, copper wire connected to the ground wire, will make the display cabinet appear leakage phenomenon, which can be eliminated after maintenance.

3. The power cord is worn. The insulation layer is damaged. The power cord is damaged due to deterioration, moisture and wear of insulating plastic. At this time, the power cord should be updated in time.

. 4. There is an error in wiring. The ground wire of the display cabinet is connected with the power wire, and the display cabinet is electrified due to the unbalanced three-level load of the power grid or the open circuit of the zero line, so the wiring must be correct.

5. The compressor unit leaks. Check or replace the compressor In order to ensure personal safety, three sockets should be considered in the design of the display cabinet. Don't use wet hands to switch on and off live display cabinets. If it is necessary to clean the display cabinet, it should be done after cutting off the power supply. 6. The display cabinet is poorly grounded. The display cabinet is poorly grounded. For example, if the display cabinet is placed on a bench with rubber wheels or on an insulator such as wood glue, the bench should be removed immediately to ensure safety.
