Rack mounting
UL guidelines
The following Underwriters Laboratories (UL) guidelines
pertain to the installation of the FOX 4G DA8 into a rack
(gure 2-1).
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 +122 °F
(+50 °C) maximum ambient temperature (Tma) specied
by Extron
2. Reduced air flow — Installation of the equipment in a rack
should be such that the amount of air ow 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).
