Drilling Holes

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.

  • Before you drill a hole in the cabinet, wear insulated gloves and remove the internal cables from the cabinet.
  • Wear an eye protector when drilling holes. This is to prevent your eyes from being injured by the splashing metal scraps.
  • Ensure that the scraps caused by drilling do not enter the cabinet.
  • Drilling holes without complying with the requirements affects the electromagnetic shielding performance of the cabinet.
  • After drilling, clean the metal scraps immediately.
