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. Therefore, consider installing the equipment in an
environment compatible with the maximum ambient temperature specified by Extron
(Tma = +32 to +122 °F [0 to +50 °C]).
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.
Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
Circuit overloading — Consider 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. Use appropriate consideration of equipment nameplate ratings when
addressing this concern.
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).
