If installed in a closed or multi-unit rack assembly, the ambient
operating temperature of the rack environment may be greater than the
ambient temperature of the room. Therefore, consideration should be
given to installing the equipment in an environment compatible with
the manufacturer's maximum rated ambient temperature (Tmra).
Equipment should be mounted into a rack so that the amount of air
flow required for safe operation is not compromised.
Equipment should be mounted into a rack so that a hazardous
condition does not arise due to uneven mechanical loading.
Consideration should be given to the connection of the equipment to
the power supply circuitry and the effect that any possible overloading
of circuits might have on overcurrent protection and power supply
wiring. Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
A reliable ground must be maintained at all times. To ensure this, the
rack itself should be grounded. Particular attention should be given to
power supply connections other than the direct connections to the
branch circuit (i.e. the use of power strips, etc.).
