13.
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, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
14.
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.
15.
Mechanical Loading:
Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
16.
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.
17.
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).
