3. Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
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 Mounting
The XPA 1002 or XPA 2001 can be mounted in a rack shelf using the optional
RSU 129 1U Universal rack shelf (Extron part #60-190-01) or the 1U Basic rack shelf
(Extron part #60-604-02), as follows.
1. If feet were installed on the bottom of the amplifier, remove them.
2. • Place the amplier on one half of the rack shelf.
• Align the front of the amplier with the front of the shelf, and align the threaded
holes on the bottom of the amplifier with the holes in the rack shelf.
3. • Attach the amplier 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 into
diagonally-opposite corners.
See the following illustration.
Use 2 mounting holes on
opposite corners.

Using screws longer than
3/16” will damage the unit
and void the warranty.

4. Attach the false front panel (provided with rack shelf part #60-190-01) to the
unoccupied side of the rack (as shown above), or install a second half-rack-width
device in that side by repeating steps 1 through 3.
5. Attach the rack shelf to the rack using four 10-32 x ¾” bolts (provided). Insert the
bolts through #10 beveled washers, then through the holes in the rack, as shown
above.
