18. Operating Temperature
An operating temperature range is specified (see Appendix F, Specifications) so that
the customer and installer may determine a suitable operating environment for the
equipment.
19. 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, consideration
should be given to installing the equipment in an environment compatible with the
specified operating temperature range.
20. Reduced Air Flow
Installation of the equipment in the rack should be such that the amount of airflow
required for safe operation of the equipment is not compromised.
21. Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition is
not caused by uneven mechanical loading.
22. Circuit Overloading
Consideration should be given to connection of the equipment to supply circuit and
the effect that overloading of circuits might have on over-current protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
23. Reliable Earthing (Grounding)
Reliable grounding of rack mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the
branch circuit (for example, use of power strips).
