Mounting the Unit
C
Installation and service must be performed by
authorized personnel only.
Any of the 1" high, quarter-rack width units can be placed on a
tabletop, mounted on a rack shelf, or mounted under or through
a desk or other furniture.
C
The FOXBOX 4G units generate heat during
operation. Ensure there is ample room between
units in multiple unit installations for ventilation
and/or ensure adequate equipment cooling. Units
too close together may overheat.
Tabletop placement
Affix the four included rubber feet to the bottom of the unit and
place it in any convenient location.
Rack mounting
UL guidelines
The following Underwriters Laboratories (UL) guidelines
pertain to the installation of a FOXBOX 4G transmitter or
receiver into a rack (figure 2-1).

.
Elevated operating ambient —
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
maximum ambient temperature (Tma) of +122 °F (+50 °C)
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).
