Rackmount Instructions
1. 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.
2. 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.

3. Mechanical Loading - Mounting of the equipment in the rack should
be such that a hazardous condition is not achieved due to uneven
mechanical loading.
4. 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.
5. 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)."
