Delta's inverters should be thoroughly inspected for the first time or after long-term installation. The items and methods of inspection are as follows:
1) Check whether the Delta inverter is damaged, whether the metal parts are rusty, and whether there is frost. If frost and dew are formed, they should be dried for 4 hours (60°C) or ventilated at room temperature for 24 hours.
2) Regarding the low-power Delta inverter, gently turn over the case, pay attention to whether there is any abnormal sound in the case, if there is any abnormal sound, open the case, look for and eliminate foreign objects.
Delta inverters
3) For Delta inverters with high power, please open the shell, check whether there are fallen wires and shaking bolts during transportation and storage, and re-weld or tighten them.
4) Conduct electrical testing and inspection of Delta inverters according to the needs of the inverter at the front end of the device, pay attention to the characteristics of different inverters, and test and inspect them according to their characteristics.

Analysis of the power-on trip problem of Delta inverter
In life and production, leakage switches are often used. But the inverter is not used much at some times. Most manufacturers often use leakage switches as the main switch when installing switches in the workshop. When the frequency conversion control is elected, the problem comes out, and the leakage switch is always tripped after a little moment...

Introduction to the basic application of Delta inverter
Generally, household appliances use a single-phase asynchronous motor, which relies on capacitance or resistance to split the phase. Motors are often in a short-term repetitive state (on/off) during operation, such as air conditioners, refrigerators, etc. This will inevitably lead to frequent starting, high noise, short motor life, poor temperature stability and energy consumption.
