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.
