Rack Mounting Safety Precautions
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
temperature. Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Reduced Airflow: Installation of the equipment in a rack should be such that the amount of airflow
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: 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).
