Mounting the NetPA Ultra Series Amplifiers

The NetPA Ultra Series amplifiers 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.
This guide uses images of the NetPA U 1004 to describe installation, but all the amplifiers are installed
the same way.

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.

Mounting the NetPA Ultra Series Amplifiers
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).
