Equipment maintenance: drawer retrofit

Retrofitting a drawer consists of replacing the old one whose equipment became obsolete. Often we have to change the entire drawer to keep the correct elements arrangement. In this way the drawer is a tested unit that complies with the requirements of the standard. Modernise a part in the drawer brings changes in the elements layout and sometimes it is not possible without change the other elements too.
