2.	Mount the PS 123 on the rack shelf, using two 4-40 x 3/16"
	screws in opposite (diagonal) corners.
3.	If necessary, mount the half rack width false front panel
	(included with the Universal Rack Shelf only) and/or the

quarter rack width false front panel (included with the PS 123) to the shelf, using two 4-40 x 3/16" screws in the front holes for each panel.

Under-desk mounting

In addition to using the PS 123 power supply on a rack or projector, it can also be mounted under furniture (such as a desk) using the MBU 125 Under-Desk Mounting Kit (part

#70-077-01). To mount the PS 123 under a desk or other furniture, follow these steps:

1.	Attach the mounting brackets to the power supply with
	the provided machine screws (figure 9).
2.	Hold the power supply with the attached brackets against
	the underside of the furniture. Mark the location of the
	screw holes of the bracket on the mounting surface.
3.	Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm)
	deep in the mounting surface at the marked screw
	locations.

5.	Align the mounting screws with the slots in the brackets
	and place the power supply against the surface, with the
	screws through the bracket slots.
6.	Slide the unit slightly forward or back, then tighten all four
	screws to secure it in place.
