Mounting the XPA U 3502 Amplifier

The XPA U 3502 can be mounted in a rack using rack ears, mounted on a rack shelf, set
on a table, or mounted in the plenum space above a ceiling-mounted projector. Also, two
amplifiers can be connected using the bridging plate to create a full rack-width unit.

Tabletop Use

Four self-adhesive rubber feet are included. Attach one foot at each corner on the bottom
side of the amplifier and place the unit in a desired location.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
equipment in a rack.

Flexible Conduit Adapter Kit Installation
Elevated operating ambient temperature — If the equipment is 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 = +32° F to
+122° F (0° C to +50° C)/ 10% to 90%, noncondensing) specified by Extron.
Reduced air flow — Install the equipment in a rack so the amount of air flow required
for safe operation of the equipment is not compromised.
Mechanical loading — When mounting the equipment in the rack, ensure uneven
mechanical loading does not cause a hazardous condition.
Circuit overloading — When connecting the equipment to the supply circuit, consider
the effect circuit overloading might have on overcurrent protection and supply wiring.
Consider equipment nameplate ratings when addressing this concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (for example, use of power strips).
