WIRING DIAGRAMS FOR YOUR STEP-DOWN ARE PART OF THE OPERATOR'S MANUAL. You can CREATE an enlarged and more usable chart by taking your manual diagram to a print shop to have it photocopied as an enlarged image. For ease of use have the enlarged diagram laminated with heavy laminate.  Your diagram will be usable for years.
