Mounting the NetPA U 2002 SB Amplifier

The NetPA U 2002 SB amplifier can be mounted in a rack using the included 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.

Rack Mounting
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, using power strips).
