The box where the card is installed is considered to be a metallic and/or plastic
box.
Inside, the plate of the box is suggested to have a drilling pattern like the one
shown in figure 4, for the mounting of the card when using “mounting bars” (see
also ANNEX A). Consult drawings (see ANNEX A) for the drilling pattern of the card
it self.
