High speed door controller installation preparations

High speed door controller installation preparations

1. Before wiring, ensure that the input power is cut off.

2. Please confirm whether the power supply voltage of the main loop is consistent with the rated voltage of the controller, and ensure that the grounding terminal is reliably grounded.

3. Do not touch the output terminal directly, and do not short-circuit the output terminal or connect it with the shell.

4. After the AC power is cut off and before the LCD display of the controller goes out, there is still high voltage inside the controller. Do not touch the internal circuit and electronic components.

5. the electronic components in the controller are particularly sensitive to static electricity, so do not put foreign matter inside the AC motor driver or touch the main circuit board.
