When using a hard power cord, fix it near its terminal so as to free the terminal and the cable from stress;

Do not use tapping screws to fasten the connecting terminals;

The power cords of the same type and in the same direction should be bundled together and kept neatly and straight;

The following table lists the requirements in the bundling with cable ties.
