Rack mounting — Attach the DSC to a standard 19-inch rack shelf. The
following Underwriters Laboratories (UL) guidelines pertain to the installation of the
DSC 401 and 401 A in a rack:
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 = +122 °F, +50 °C) specified by Extron.
Reduced air flow — Install the equipment in the rack so that the amount of air
•
flow required for safe operation of the equipment is not compromised.
•
Mechanical loading — Mount the equipment in the rack so that uneven
mechanical loading does not create a hazardous condition.
•
Circuit overloading — When connecting the equipment to the supply circuit,
consider the effect that circuit overloading might have on overcurrent protection
and supply wiring. Consider equipment nameplate ratings when addressing this
concern.
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
•
equipment. Pay particular attention to supply connections other than direct
connections to the branch circuit (such as the use of power strips).
Under-furniture mounting — Mount the DSC under the surface of a desk, table, or
podium.
NOTE: Ensure that none of the vents on the unit are blocked.
Through-furniture mounting — Mount the DSC through a table or desk in which a
hole has been cut to enable access to the front panel.
Free-standing — Attach the included four rubber feet to the bottom of the DSC in the
four corners and place the unit on furniture as desired.
