Preparing To Assemble The Xpresschannel; Assembling The Xpresschannel - Overland Data DLT LibraryXpress Series Service Manual

Figure 2-4 shows a typical XpressChannel assembly. The motor drive section always goes on
top, and the base section with the idler pulley always goes on the bottom. Extension sections
are mounted between the motor drive section and the base section. All sections are joined
together with tie bars. For systems up to four modules, two support braces are needed, one
attached to the motor drive and one to the base section. For larger systems, a third support
brace should be mounted near the center of the XpressChannel.

Preparing to Assemble the XpressChannel

You will need a clean, flat work area such as a table or work bench. The surface should be
long enough to support the full height of the XpressChannel. The height is equal to the height
of the stack of modules in your system plus any gaps you intend to include in the stack. Use
the following procedure to assemble your XpressChannel.

Assembling the XpressChannel

In most cases, you have received a pre-assembled XpressChannel. If its length is correct for
your system, turn to the section titled 'Mounting the Module Rack Slides' and continue on to
the end of the chapter. If you need to add sections, please take a few minutes to read this
section and the next section on installing the belt before proceeding to the section titled
'Adding to an Existing XpressChannel.'
Note: References to left and right refer to the position of the part when the XpressChannel is
assembled and mounted in the rack, as viewed from the front of the rack.
Refer to Figures 2-1 and 2-4.
1. Place the base section, with the inside facing down, overhanging the right end of the
work area, with the bottom plate of the section toward the right.
2. Place each of the extension sections, with the inside facing down, in a row aligned
edge-to-edge beginning with the base section. The bottoms of the sections should be
toward the right. Omit the motor drive at this time.
3. Center one of the support braces across the rear of the base section over the holes on
the rear surface of that section. Be sure that the word 'LEFT' that is stamped on the
brace is upright.
4. Insert two M4 x 20 Phillips sems screws through the holes in the support brace into
the holes in the base section, and tighten.
