American Power Conversion 5000I user manual Install the Mounting Rails in the Rack

Determine the Location of the UPS in the Rack (continued)

1.Determine where in the rack you’ll mount the UPS. The SU5000 requires a space of 5U. Some racks have tick marks to indicate

	the U-spaces.
2.	Using the mounting template provided (part number 990-0195),
	identify and mark the correct mounting holes for the UPS
	mounting brackets.
3.	Locate and mark the bottom hole in the designated U-space ￿.
￿	The bottom screw on the mounting rail will attach to the bottom
	hole in the U-space.
4.	Repeat steps 3 and 4 for the remaining three rack posts.
5.	Prepare the rack holes, if necessary. Racks with threaded holes
	require no preparation.
	If your rack has round holes, insert clip nuts	(provided) into
	the holes in step 2.
	If your rack has square holes, insert either clip	or cage
	nuts into the holes marked in step 2 (cage nut shown).

￿

Remove the two screws ￿ that hold the rails together so that the rails can slide outward ￿. Do not detach the rails.

Front

Align the bottom hole on the mounting rail with the bottom hole in the U-space (marked in step 3 above). Use the flat, Phillips head screws (10-32) and conical washers to attach the front rail to the rack. Position the rails so that the lip of the rail is on the bottom.

3 4

Expand the rails so that it spans from the front rack post to the back rack post. Replace the two screws (removed in step 1) that hold the rail sections together.

Back

Attach the rail to the back rack post using the same hardware (10-32 flat head screws and conical washers) used in step 2. Repeat the process for the other rails.
