5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack mount the unit using an optional Extron 2U universal rack shelf (Extron part #60-032-01), as follows:

1.	Remove rubber feet if they were previously installed on
	the bottom of the unit.
2.	Place the DA on one side of the optional 2U (two unit high,
	19" wide) rack shelf (Extron part #60-032-01). Align the
	front of the DA with the front of the shelf, and align the
	threaded holes on the bottom of the DA with the holes in
	the rack shelf.
3.	Secure the DA to the rack shelf with the two provided
	4-40 x 3/16" machine screws. Insert the screws from the
	underside of the shelf, and securely fasten them through
	diagonally opposite corners.
4.	Fasten the false front panel (provided with the rack shelf)
	to the unoccupied side of the rack (as shown below), or
	install a second half-rack-width device in that side by
	repeating steps 1 through 3.
5.	Secure the rack shelf to the rack using four 10-32 x ¾" bolts.
	Insert the bolts through #10 beveled washers, then through
	the holes in the mounting brackets.
