Installation, cont’d
2-4
1. Elevated operating ambient temperature — If installed
in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be
greater than room ambient temperature. Therefore, install
the equipment in an environment compatible with the
maximum ambient temperature (Tma = +122 °F, +50 °C)
specied by Extron.
2. Reduced air flow — Install the equipment in a rack so that
the amount of air flow required for safe operation of the
equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack
so that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading 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) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g. 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 #60-604-01),
as follows.
1. If feet were installed on the bottom of the amplifier,
remove them.
2. • Place the amplier on one half of the rack shelf.
• Align the front of the amplier 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 amplier 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.
