Tabletop placement
Affix the four included rubber feet to the bottom of the unit and
place it in any convenient location.
Rack mounting
UL requirements
The following Underwriters Laboratories (UL) requirements
pertain to the installation of the FOX HD-SDI transmitter or
receiver into a rack (figure 2-1).
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. Therefore, consider installing the
equipment in an environment compatible with the +122 °F
(50 °C) maximum ambient temperature (Tma) specified by
Extron.
2 . Reduced air flow — Installation of the equipment in a rack
should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
3 . Mechanical loading — Mounting of the equipment in
the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
4 . Circuit overloading — Consideration should be given to
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits 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) — Reliable earthing
of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as
the use of power strips).
Mounting instructions
For optional rack mounting, mount the transceiver on any of the
following rack shelves:
• RSF 123 3.5" deep 1U VersaTools
® rack shelf kit
(part #60-190-20) (figure 2-1)

Figure 2-1 — Mounting the transceiver on a
VersaTools rack shelf
On the non-VersaTools rack shelves, the transceiver unit can be
mounted in the front or the rear of the rack.
1
. If installed, remove the feet from the bottom of the unit.
2 . Mount the unit on the shelf, using two 4-40 x 3/16" screws
in opposite (diagonal) corners to secure the unit to the
shelf.
3 . Install false faceplate(s) or other unit(s) to the rack shelf.
4 . Insert the shelf into the rack, aligning the holes in the shelf
with those of the rack.
