Mounting the AVT 100
The AVT 100 demodulator can be set on a table or mounted on a
rack shelf.
Tabletop use
Four self-adhesive rubber feet are included with the AVT 100.
For tabletop use, attach one foot at each corner on the bottom
surface of the unit, and place the unit in the desired location.
Rack mounting
For optional rack mounting, do not install the rubber feet.
Mount the AVT 100 on an RSU 129 Universal Rack Shelf Kit
(part #

or an RSB 129 Basic Rack Shelf (part
#
60-604-01

UL requirements for rack mounting
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the equipment in a rack.
1
.
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 = +113 °F, +45 °C) specified 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).
