Installing the PVT Twisted Pair Transmitters
The PVT CV is a 1/8 rack shelf mountable transmitter, and
the PVT RGB, PVT RGB CV, and PVT SW RGB are 1/4 rack
shelf mountable transmitters. Each of the four models can
be mounted under a desk or shelf, or on to certain projector
mounts, and are also suitable for tabletop use.
Tabletop use
The PVT comes with self-adhesive rubber feet attached to the
four corners of the bottom. Set the PVT on a horizontal surface.
UL requirements for rack mounted devicesnted devices
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the PVT transmitter in a rack.
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 device
in an environment compatible with the maximum ambient
temperature (Tma = +122 °F, +50 °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).
Rack mounting
For rack mounting, mount the PVT on a VersaTools

19" 1U
rack shelf (RSF 123, part #60-190-20 or RSB 123, #60-604-20)
(figure 2-1) or on a standard 1U rack shelf (RSU 129, part #60-
190-01 or RSB 129, #60-604-01) (figure 2-2). On standard rack
shelves, the PVT CV can be mounted in one of eight locations to
the rear or the front of the rack, and the PVT RGB and RGB CV
in one of four locations to the rear or front of the rack.
