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 maximum
122 °F (50 °C) (CrossPoint 450 Plus) or 113 °F (45 °C (MAV Plus) ambient
temperature (Tma) specified by Extron.
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 — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
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.
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 (e.g.
use of power strips.
Insert the switcher into the rack, aligning the holes in the mounting bracket
with those in the rack.
