•With the shelves facing down, align the base opening with the column. Carefully
route the six cables hanging from the bottom of the cart column one at a time through
the opening in the cart base. The opening allows the column to be fitted in only one
way (see FIGURE 4). Slide the cart base onto the column’s two alignment threaded
studs (FIGURE 7). Note: packaging of cart may include foam and caps for the studs
which will need to be removed prior to assembly.
NOTE: The sixth cable is for the optional page printer. It is included but not shown in
FIGURE 4 or FIGURE 7.

•Hand-tighten the plastic nut at the base of the main switch if it is loose (FIGURE 7).
Insert nuts with integrated lock washers onto each of the two threaded studs with the
lock washer towards the column, and then tighten the nuts using the 7/16” wrench.
Tighten until snug, and then tighten at least an additional half turn so that lock washer
bites into base metal. Insert the four socket head cap screws with washers and
tighten using the T-handle 3/16” allen wrench (FIGURE 8 and FIGURE 9). Tighten
until snug, then tighten at least another half turn.

•Loosen the attached thumb screw. Slide the power supply into the box from the front
so that the end that connects to the cable from the transformer faces toward the front
of the cart assembly. Route the cable that connects to the Panel PC through the
lowest opening in the cart column to the back of the column (FIGURE 12), up along
the back of the column. Do not route the output cord through the highest opening
until the Panel PC is in place.

4. Install the Panel PC
•Stand the assembled cart column upright on the cart base. Unpack the Panel PC
and lay it face down on a flat surface. CAUTION: To avoid scratching the screen
surface, DO NOT remove the protective film until the ALGO 5 is completely
assembled.
•On the recessed flat surface at the back of the Panel PC, there are four screw holes
used to mount the PC to the PC mount (FIGURE 14). Using the 90-degree 5/32”
allen wrench provided (FIGURE 13), place socket head cap screws (#10-32 x
1/2“ SHCS) into the top two inner holes and tighten until the screws stop, then loosen
a full five rotations (1/8” space between screw and plastic).
