2. Then connect the connecting wire and plug of the universal board. Connect the power cord of the universal board to the power plug of the original circuit board, and pay attention to the corresponding polarity. Then insert each sensor plug of the universal board into the corresponding position on the original circuit board in turn, and pay attention to the position and corresponding number of each plug.
3. Install the new universal board on the circuit board seat of the disinfection cabinet, and then cover the shell.
4. Connect the power supply, open the disinfection cabinet and test. During the test, it is necessary to check whether all sensors of the universal board work normally, such as temperature sensor, humidity sensor, time controller, etc. If the test is correct and the wiring is successful, it can be used normally.
