In the design of the frequency converter, it must be avoided to connect the power supply to the output terminal to prevent short circuits. If the input line is incorrectly connected, it will cause the high-voltage power supply to flow directly into the frequency converter, causing equipment failure.
Input and output terminal connection
In the design of inverters, it is necessary to avoid connecting the power supply to the output terminal to prevent short circuits.
Consequences of the failure
If the input line is incorrectly connected, it will cause the high-voltage power supply to directly flow into the frequency converter, causing equipment failure.
