Do not drill the cabinet at will. Drilling holes without complying with the requirements affects
the electromagnetic shielding performance of the cabinet and damages the cables inside the
cabinet. In addition, if the scraps caused by drilling enter the cabinet, the printed circuit
boards (PCBs) may be short circuited.
