Installation

3.4.1 Component Identification

Mechanical layout drawings are provided inside the cover of each unit with an option panel. These illustrations are intended
to provide the installer or equipment user with component identification and location for that specific unit. Illustration 3.7
and Illustration 3.8 represent a typical layout drawing. Table 3.3 provides definitions for drawing reference designators. (Not
3 3 all reference designators are shown.)
